Suitably, a pair of biasing members such as a spring  206  (only one spring is depicted in  FIG. 6  for clarity) are provided for use in mounting and engagement of the printhead mounting assembly  240 . If coil springs such as spring  206  are used for the biasing members, it is suitable that the printhead mounting assembly  240  include a corresponding number of retention posts  209  that extend from an upwardly directed face of the mounting assembly  240 . The retention posts  209  serve to retain and maintain the position of a spring  206 . It will be appreciated that in no way is the invention limited to this particular configuration. The printhead  205  is affixed along an underside of the assembly  240  by one or more fasteners  208 . The printhead  205  is generally positioned between the underside of the assembly  240  and the printhead retainer  230  illustrated in  FIG. 5 . Additional details of those components are provided herein. 
       FIG. 7  is an exploded view of the drive module assembly  300  used in the labeler/printer  10 . The assembly  300  comprises a pair of frame sections  302   a  and  302   b . The frame sections  302   a  and  302   b  are sized, shaped, and configured to engage one another and provide an interior region within which are disposed various components as follows. One or more, and suitably two, supply flanges  310 , and one or more, and suitably two, supply holders  312   a  and  312   b  are movably disposed within the interior region defined between the frame sections  302   a  and  302   b . Each flange  310  is rotatably engaged with a corresponding holder  312   a  and  312   b . As described in greater detail herein, the sets of flanges  310  and holders  312   a  and  312   b  can be selectively positioned at different distances from one another to thereby accept and retain a wound roll of paper or media for use with the labeler/printer  10 . The drive module assembly  300  also comprises an electrically powered motor  320  mountedly disposed within the frame sections  302   a  and  302   b . The motor  320  provides rotational power to a drive gear  322 . The drive gear  322  is engaged with a platen gear  324  and a liner drive gear  328 , suitably via one or more idler gears  326 . All or a portion of the gears described herein can be retained to a frame section such as section  302   b  by a retaining clip  327 . Powered rotation of the platen gear  324  imparts rotation to a platen roller  340 . And, powered rotation of the liner drive gear  328  imparts rotation to a liner drive roller  350 . Each roller  340  and  350  is rotatably supported and mounted between the frame sections  302   a  and  302   b . Although a wide array of mounting configurations can be used, suitably each of the platen roller  340  and the liner drive roller  350  are rotatably received by a pair of bearings  344  disposed in aligned apertures in the frame sections  302   a  and  302   b . The drive module assembly  300  also comprises a peel roller  355  also extending between the frame sections  302   a  and  302   b . The operation of these components is described in greater detail herein. 
     Referring further to  FIG. 7 , as noted, the spacing between the two sets of the supply flange  310  and the supply holders  312   a  and  312   b  is selectively variable. Thus, a user can selectively position each set of flange  310  and holder  312   a ,  312   b  along their axis of rotation within the interior region defined between the frame sections  302   a  and  302   b . Suitably, relative spacing between the sets of flanges and holders may be biased to one or more predetermined default spaces. This feature enables the sets of flanges  310  and holders  312   a ,  312   b  to be readily adjusted to fittingly receive wound rolls of paper or media of common or industry standard widths. A stop guide  380 , a retainer  382 , and an idler gear  384  provide this feature and are periodically referred to herein as a spacing selection assembly  378 . The stop guide  380  is slidably positionable and depending upon its position, laterally displaces corresponding cam followers formed on the supply holders  312   a  and  312   b  and thereby positions the holders  312   a  and  312   b  apart or closer together. For example, one cam follower  313   b  formed on the supply holder  312   b  is illustrated in  FIG. 15 . Suitably, a similar cam follower (now shown) is also formed on the supply holder  312   a . Since the flanges  310  are mounted on and thus carried by the supply holders  312   a  and  312   b , the flanges  310  are also linearly displaced relative to one another as the stop guide  380  is repositioned. One or more biasing members or springs  386  can be used to urge the sets of flanges  310  and holders  312   a  and  312   b  apart or closer together. Additional details of the spacing selection assembly  378  are provided in  FIG. 15  and the associated description herein. As will be understood, the frame sections  302   a  and  302   b  can be secured to one another in a variety of different ways. One or more threaded fasteners  394  are suitably used. 
     One or more sensors  390  can be used to detect indexing and/or other like marks on an underside of the web or media threaded through the labeler/printer  10 . Suitably, a backside or surface such as the wall or plate  230   a  of the print head retainer  230  defines at least a portion of the web path and limits the distance at which the web can pass by the sensor  390 , thereby aiding accurate sensor readings of indexing and/or other like marks on an underside or back surface of the web. 
       FIG. 8  is a detailed perspective view of the front nose end  42  of the labeler/printer  10  revealing various aspects of the drive module assembly  300  and the print module assembly  200  generally positioned above the drive module assembly  300 . In  FIG. 8 , the labeler/printer  10  is shown without associated covers or housings to better reveal the interior of the labeler/printer  10 . Drive gear  322  is illustrated showing its engagement with the platen gear  324  and the liner drive gear  328  via the idler gear  326 . The application roller  286  associated with the print module assembly  200  is suitably positioned forwardly and above the gears. A unique feature of the labeler/printer  10  is the location of the application roller  286 . Locating the roller  286  relative to other components along the front nose end  42  while retained in the pivotable print module assembly  200  as shown eliminates or at least significantly simplifies “threading” paper, media or web through the labeler/printer  10  during supply loading. The deflector door  360  is also shown, located immediately below the application roller  286 . As explained in greater detail herein, the deflector door  360  is positionable between a closed state (shown in  FIG. 8 ) and an open state. Latch actuators  210  are suitably located along lateral side regions of the labeler/printer  10  and upon actuation, enable the print module assembly  200  to be released so that it may pivot from a closed position shown in  FIG. 8  to a raised or open position, thereby enabling access into the interior of the labeler/printer  10 . 
       FIG. 9  is another detailed perspective view of the front nose end  42  of the labeler/printer  10  illustrating further aspects thereof. In this view, the application roller  286  has been removed along with the deflector door  360  for greater clarity. As can be seen, the platen roller  340  is disposed above the liner drive roller  350 . Optionally, the liner drive roller  350  is over-driven with respect to the platen roller  340 . That is to say, the liner drive roller  350  is rotatably driven at a speed or amount greater than the platen roller  350 . This configuration serves to maintain tension on a liner layer described in greater detail herein. Increased tension on the liner promotes separation of a label or facestock layer from the liner, particularly as the liner is pulled over the peel bar or roller  355 . This is described in greater detail in conjunction with  FIG. 22  which illustrates a paper path defined in the labeler/printer  10 . Another unique feature of the labeler/printer  10  is the location of the liner drive roller  350 . Locating the roller  350  relative to other components as shown in  FIG. 9  eliminates or at least significantly simplifies “threading” paper or web through the labeler/printer. The liner drive roller  350  is generally located below the platen roller  340  and in contact with the pressure roller  370 . As previously described, the pressure roller  370  is rotatably supported and mounted on the deflector door  360  which is not shown in  FIG. 9  for greater clarity. As previously noted, rollers  340  and  350  are driven by gears  324  and  328 , respectively. Only a portion of the drive frame section  302  is depicted. The latch actuator  210  and its associated latch bar assembly  212  is also shown. 
       FIG. 10  is another detailed perspective view of the front nose end  42  of the labeler/printer  10  revealing additional aspects thereof. In this view, the various housing portions and covers have been removed, the deflector door  360  is removed, application roller  286  is removed and a right hand side portion of the drive frame section  302   b  has been removed for greater clarity.  FIG. 10  illustrates the relative positions of the pressure roller  370  and the liner drive roller  350  when the deflector door (not shown) is closed. As can be seen, the pressure roller  370  is in close proximity and suitably in contact with the liner drive roller  350 . The liner deflector door (not shown) is hingedly or pivotally mounted on a hinge post  362  or other suitable member along the front region of the labeler/printer  10 . 
       FIG. 11  is yet another detailed perspective view of the front nose end  42  of the labeler/printer  10 . In this view, various housing and cover portions have been removed along with certain electronics and the application roller  286 , and the deflector door  360  is depicted in an open position. The pressure roller  370  is rotatably supported along an interior face of the deflector door  360 . Mechanical stops are provided in the hinge assembly for the deflector door  360  so that the door does not extend beyond its fully open state depicted in  FIG. 11 . 
       FIG. 12  is a front perspective view of a subassembly of a portion of the print module assembly  200  and a portion of the drive module assembly  300  of the labeler/printer  10  in conjunction with other components. Specifically, the latch bar assembly  212  and laterally disposed latch actuators  210  are shown removed from their engagement with the frame  270  of the print module assembly  200 . Laterally located and partially exposed support members  214  are fittingly received in apertures  269  defined in the frame  270  of the print module assembly  200 . The latch bar assembly  212  engages the frame  270  of the print module assembly  200  and is suitably retained therewith by the pair of apertures  269  and biased rotatably forward by biasing frame members  216 . Due to the arcuate inverted U-shaped configuration of the frame members  216 , the forward portion of the bar assembly  212 , particularly the portion carrying the latch actuators  210 , can be forwardly or rearwardly displaced. Thus, by forward or rearward displacement of the latch actuators  210  and associated latch fingers  211  relative to a corresponding stationary latch engagement member  304  in the drive module assembly frame  302 , the latch bar  212  and pivotable print module assembly  200  can be selectively secured to or released from affixment with the frame  302  of the drive module assembly  300 . The provision of dual latch actuators  210 , each accessible and provided on opposite side regions of the labeler/printer  10  along with the rearward action or movement used to operate the latch actuators  210  greatly minimizes or in many instances, eliminates unintended or accidental actuation of the latch assembly which could otherwise potentially occur if the labeler/printer  10  is laid on its side by an operator. 
       FIG. 13  is a rear perspective view of the drive assembly  300  in conjunction with the printhead mounting assembly  240 . It will be understood that upon assembly and incorporation of the printhead mounting assembly  240  in the print module assembly  200 , the underside of the printhead mounting assembly  240  at which is located the printhead (not shown) is in close proximity to the platen roller  340  so that paper or other material passes underneath and is immediately adjacent to the printhead  205 . This configuration is illustrated and described in conjunction with  FIGS. 21 and 22 . The motor  320  is also illustrated in  FIG. 13  and its orientation in the drive assembly  300 . 
       FIG. 14  is another rear perspective view of the drive assembly  300  and the printhead mounting assembly  240  as depicted in  FIG. 13 , however partially disassembled. Specifically,  FIG. 14  reveals the drive assembly  300  having a portion of the left hand side drive frame section  302   a  removed. In addition, the printhead mounting assembly  240  is spaced from the platen roller  340  for greater clarity. The sets of supply flanges  310  and supply holders  312   a  and  312   b  mounted within the drive frame sections  302   a  and  302   b  are illustrated.  FIG. 14  illustrates a mounting configuration for the printhead mounting assembly  240 . Suitably, the assembly  240  defines a pair of forwardly directed alignment or locating surfaces  244  which, upon assembly of the printhead mounting assembly  240  in the labeler/printer  10 , directly contact exposed regions of the bearings  344  associated with the platen roller  340 . This configuration between alignment surfaces  244  and platen roller bearings  344  ensures proper and consistent positioning of the printhead (not shown) retained along the underside of the assembly  240  and the platen roller  340  upon which is carried paper or other stock to receive printing. The printhead mounting assembly  240  also provides a pair of rearwardly located and laterally projecting mounting pins  246 . Each pin  246  is received in horizontal slots of an upper frame (not shown) in the print module assembly  200 . As noted, the printhead mounting assembly  240  suitably has a segmented body to enable the assembly  240  to undergo deformation and/or movement in certain directions while resisting such and thereby provide support with respect to force loadings in other directions. Suitably, the assembly  240  includes a center rib  248  that extends substantially the entire length from front to back of the assembly  240  and connects a frontward portion  240   a  of the assembly  240  and a rearward portion  240   b  of the assembly  240  to one another with a gap between the aforementioned frontward and rearward portions  240   a  and  240   b . As shown, the rib  248  comprises a vertical wall which is flexible to twisting about its longitudinal axis X, while remaining substantially rigid to bending vertically about this axis. In the illustrated embodiment, one or more slots or regions of separation  247  define the aforementioned gap. Suitably, the assembly  240  has two symmetrically arranged slots  247  extending laterally outward from the center rib  248 . This configuration enables rotational or “gimbal” movement of a frontward portion  240   a  of the assembly  240  about the axis X such as shown by arrows A and B, while the rearward portion  240   b  of the assembly  240  is secured or mounted to one or more frame members within the labeler/printer  10 . The biasing members  206  bias the frontward portion of the assembly  240  toward an aligned position with respect to the platen roller  340 , while still allowing the printhead  205  mounted under the frontward portion  240   a  to gimbal with respect to the underlying platen roller  340  along with the corresponding movement of the frontward portion  240   a  of the assembly  240 . 
       FIG. 15  is a rear perspective view of the drive module assembly  300 , similar to  FIG. 14 , illustrating the spacing selection assembly  378  for conveniently positioning the sets of supply flanges  310  and supply holders  312   a  and  312   b  in one of several predetermined spaced arrangements. In this figure, the left hand side drive frame  302   a  and left hand side supply holder  312   a  and associated flange  310  are not shown for greater clarity of the spacing selection assembly  378 . Specifically, with reference to both  FIGS. 7 and 15 , the spacing selection assembly  378  includes the stop guide  380  having an outwardly facing contact member  381  that can be serrated or otherwise roughened to promote engagement by a user. The stop guide  380  is slidably retained within a channel (not shown) defined in the frame sections  302   a  and  302   b  of the drive module assembly  300 . The stop guide  380  is selectively movable in forward or rearward directions shown by arrow C in  FIG. 15 . Defined along lateral side regions of the stop member  380  are a collection of cam or stop surfaces  380   a  and  380   b . Ribs or cam followers (e.g., such as the illustrated cam follower  313   b ) extending from the supply holders  312   a  and  312   b  contact one of the stop surfaces or none. The selection of the surface  380   a ,  380   b  or none that contacts the rib(s) or cam follower(s), depends upon the position of the stop member  380  along a path extending in a direction of arrow C. Each supply holder  312  also suitably includes a projecting supply guide  311 . The supply guides  311  serve to contact an outer edge of the other webbing used in the labeler/printer  10 , thereby promoting additional guidance of the web within the labeler/printer  10  between the roll  5  and the nip. The present invention includes a wide variety of different versions of the spacing selection assembly  378 . For example, the provision of a greater number of default spacings, such as four, five, or more, can be readily provided by increasing the number of stop surfaces of the stop guide  380 . 
       FIG. 16  is a perspective view of the latch bar assembly  212  used in the labeler/printer  10 . The latch bar assembly  212  includes two distally disposed latch actuators  210  arranged at opposing ends of a longitudinally extending central portion  212   a . As previously explained, the latch bar assembly  212  also includes two longitudinally aligned support members  214  that are supported in a pair of mating apertures in the print module frame (not shown) when the print module assembly is positioned in its closed state. The latch bar assembly  212  also includes a pair of biasing frame members  216  that provide a biasing action upon rotation of the assembly  212  abut support members  214  such as during displacement of the latch actuators  210  in a direction indicated by arrows D occurring during a latching operation upon closing the print module assembly  200  or a de-latching operation upon opening the print module assembly  200 . As previously described, the latch bar assembly  212  defines a pair of fingers  211 , suitably sized, shaped and configured to engage with corresponding latch engagement members or catches of the drive module assembly (not shown), upon securing the print module assembly thereto. It will be understood that the print module assembly  200  is disengaged from the drive module assembly  300  and hence, remainder of the labeler/printer, by displacement of the latch actuators  210  such as in the direction of arrow D, thereby also effecting linear displacement of the fingers  211  so that the fingers are disengaged from the stationary latch engagement members  304  of the drive module assembly  300 . It should be noted that in the illustrated embodiment the latch bar assembly  212  is a one-piece molded plastic part, it is not limited to such a construction. 
       FIGS. 17 and 18  illustrate the printhead mounting assembly  240  in greater detail. The printhead mounting assembly  240 , as previously explained, suitably includes a segmented body that enables torsional movement about a central axis as depicted in  FIG. 14 . The central axis is collinear with a center rib  248 . A pair of slots or regions of separation  247  generally extend from the rib  248  along a mid-region of the assembly  240  to lateral edge regions. The regions  247  facilitate torsional displacement of the assembly  240  about the center rib  248 . The assembly  240  also includes one or more, and suitably two, upwardly extending retention posts  209  for receiving and aligning corresponding biasing elements such as coil springs that serve to apply a biasing load on the front portion  240   a  of the assembly  240 . The assembly further includes provisions for promoting alignment of the assembly  240  and printhead (not shown) and in cooperation with an underlying platen roller (not shown). These alignment provisions are suitably in the form of a pair of upwardly extending slots formed in lateral regions of the assembly  240  which provide forwardly directed alignment or locating surfaces  244  that upon incorporation in the labeler/printer, directly abut or contact an outer surface of bearings (not shown) that rotatably support the platen roller. Although the segmented body of the printhead mounting assembly  240  can be formed in a plurality of separate components, it is suitable that the body be integrally formed and that the material selection and structural design parameters dictate the torsional loading and response characteristics of the body. This enables precise and consistent behavior of the assembly  240  under a variety of operating conditions. 
       FIG. 19  is a front perspective view of the labeler/printer  10  illustrating the print module assembly  200  in an open position, and the deflector door  360  in an open position. Located along the front nose end  42  of the print module  200  is the application roller  286 . Disposed along the front nose end  42  of the housing  20 , and accessible once the deflector door  360  is opened, the platen roller  340  and peel roller  355  are exposed. Opening the print module  200  to its opened position depicted in  FIG. 19  reveals the interior of the labeler/printer  10  and a spaced void between the two sets of supply flanges  310  and supply holders  312   a  and  312   b , for receiving a roll of paper or other rolled media. Another significant feature of the labeler/printer  10  is the provision of electrical grounding components that provide an electrical grounding path to the print module assembly  200 , and in particular, to the printhead (not shown) regardless of the position of the print module assembly  200 , e.g. either open, closed, or at any position therebetween. Suitably, the ground path is provided from the printhead  205  to a ground source in the labeler/printer  10 , by a ground wire or conductor. 
       FIG. 20  is a cross-sectional view of the labeler/printer  10  containing a roll  5  of media such as precut labels on a liner carrier member. The cross sectional view was taken along a plane extending through the center of the labeler/printer  10 , and thus bisecting the labeler/printer. 
       FIG. 21  is a cross-sectional view of the labeler/printer  10  taken along a plane parallel to a bisecting plane as in  FIG. 20 , however spaced therefrom. The offset cross sectional view of  FIG. 21  illustrates the location of the printhead mounting assembly  240  being disposed over the bearings  344  of the platen roller  340 . Suitably, and as previously described, a pair of alignment surfaces  244  defined by the printhead mounting assembly  240  are located on and in contact with an outer shoulder or portion of the bearings  344  of the platen roller  340 . 
       FIG. 22  is a detailed bisectional view, similar to that of  FIG. 20  illustrating the path for paper or a roll  5  of media when used by the labeler/printer  10 . The paper or media is drawn from the roll  5  from a lower region of the roll  5 . The material, designated as  5 , includes an upwardly directed layer  5   a  for printing and a lower liner layer  5   b . The material  5  is pulled under and in intimate contact with the printhead  205  as a result of frictional engagement with an upwardly facing portion of the rotating platen roller  340 . As will be recalled, the platen roller  340  is driven by the motor  320 . As the material  5  travels past the platen roller  340  towards the front nose end  42  of the labeler/printer  10 , the material passes the peel roller  355 . As a result of tension applied to the liner layer  5   b  by the liner drive roller  350  and the relatively small radius of the peel roller  355 , the abrupt change in direction of the liner layer  5   b  promotes separation between the layers  5   a  and  5   b . The layer  5   a  which may for example be in the form of a label containing print on an upwardly directed face and an exposed layer of adhesive on an oppositely directed face, passes under the application roller  286  as the layer  5   a  exits the labeler/printer  10 . Accordingly, a user may manipulate the labeler/printer  10 , e.g., by its handle, to apply the peeled label to a desired surface and further press and/or secure the label thereto by rolling the application roller  286  over the applied label. The liner  5   b  meanwhile is gripped by and travels between the liner drive roller  350  and the pressure roller  370  as that layer then exits the labeler/printer  10  through an aperture or other opening such as provided in the deflector door  360 . 
     Generally, the materials selected for forming the labeler/printer  10  and its various components are those providing sufficient strength and rigidity while promoting ease in manufacturing. Polymeric materials that can be injection molded are suitable for the housing and panel portions. Many of the structural components and frame members can also be formed from polymeric materials. A key consideration in material selection is dissipation of static charge build up. Thus, it is suitable for many components that the material be sufficiently electrically conducting so as to dissipate such charges to avoid detrimental charge accumulation and associated release. 
     For example, in one suitable embodiment, a first electrically conductive ground path is established from the printhead  205  to an electrical ground arranged on the circuit board  130 . Suitably, the electrical ground may take the form of a ground plate arranged on the back side of the circuit board  130  which is unseen in  FIG. 3 , for example. In the illustrated embodiment, the first electrically conductive ground path includes the printhead mount assembly  240  to which the printhead  205  is mounted and the frame  270  to which the printhead mount assembly is  240  is attached. In this case, suitably the assembly  240  and frame  270  are made from electrically conductive material, e.g., such as an electrically conductive plastic. Optionally, the springs or biasing members  206  may also be metal and/or otherwise electrically conductive so as allow electrical charge to flow between the assembly  240  and the frame  270 . Further, as shown, the frame includes a hub  273  that engages the post  120  about which the hub  273  rotates when the printhead module  200  is moved between its open and closed positions. Suitably, the hub  273  has an exposed exterior surface  273   a  which acts as at least part of the first electrically conductive ground path. That is to say, in practice, an electrically conductive ground contact  800  which is part of the cable assembly  148  is arranged to be relatively stationary with respect to the rotating hub  273  while otherwise continually abutting against the surface  273   a  thereof. Suitably, the contact  800  may be located behind a forward corner  186   a  of the bezel  186  and biased into contact with the surface  273   a  of the hub  273 . The first electrically conductive ground path is then completed by a ground wire  802  extending from the contact  800  to a connector  149  of the cable assembly  148 , which connector  149  in turn engages a corresponding connector on the circuit board  130  to complete the electrical connection with the electrical ground thereon. Notably, in this way, the first electrically conductive ground path remains unbroken regardless of the position and/or movement of the print module  200  insomuch as the contact  800  remains abutting the surface  273   a  of the hub  273  included on the electrically conductive frame  270 . Moreover, it is significant that the first electrically conductive ground path does not include any flexible portions within the print module  200  that are bent when the print module  200  is moved between its closed and open positions. In this way, each time the print module  200  is opened or closed, there is no repeated flexing or bending, e.g., of a wire or other like part, which over time could lead to breaking or failure of the repeatedly flexed part. 
     In another suitable embodiment, a second electrically conductive ground path is also established between the trigger  26  and the electrical ground on the circuit board  130 , e.g., to drain off static charge through a user touching the trigger  26  with their finger or other body part. Accordingly, the trigger  26  is optimally made of an electrically conductive material, e.g., a suitable electrically conductive plastic. Likewise, the biasing member  27  is also part of the second electrically conductive ground path. Suitably, the biasing member  27  may be the illustrated leaf spring or alternately a compression spring made from a metal or other suitable electrically conductive material. In practice, one end of the biasing member  27  contacts the trigger  26  and the other end of the biasing member may directly contact the electrical ground or ground plate on the circuit board  130  thereby pushing off from the same and biasing the trigger  26  outward or otherwise into its unactuated state. 
     It is also contemplated that electronic processors with associated memory provisions are utilized throughout the labeler/printer  10  and in one or more of its components to control and monitor their operation. For example, one or more of the previously described electronic circuit boards, “cards”, or components, such as battery board  130 , display assembly  164 , keyboard assembly  178 , electronic circuit board  180 , print engine circuit board  184 , scanner  250 , mezzanine electronic circuit board  272 , radio card  280 , and any other components of the labeler/printer  10  can include software algorithms with updating protocols to avoid having to reboot or re-initialize the associated component(s). 
     Another feature of the labeler/printer  10  is the elimination of numerous intermediate components and resulting assembly simplification. This enables higher manufacturing tolerances to be achieved. 
     The present inventive subject matter also includes a charging cradle for the labeler/printer  10 . The charging cradle can be in a variety of forms. However, one suitable form is a stationary base that slidably receives and engages the labeler/printer  10  such as along the battery enclosure  32  and in doing so, establishes electrical contact with one or more contacts such as for example electrical charging contacts  34  depicted in  FIG. 19 . Ports  22  may provide electronic communication with one or more components of the labeler/printer  10 . The ports  22  can be in any form such as for example USB, serial, parallel, and other data and signal ports. The charging cradle is suitably provided with overcharging protection provisions, correspondingly aligned electrical contacts that establish electrical communication with the contacts  34  of the labeler/printer  10  and may include addressable operations. 
       FIG. 23  illustrates an exemplary embodiment of a charging cradle  400  in accordance with aspects of the present inventive subject matter. The charging cradle  400  comprises a housing  410  that defines a receiving region  420  for receiving and engaging a portion of a labeler/printer such as the labeler/printer  10 . Suitably, the receiving region  420  receives a distal lowermost portion of the lower battery enclosure  32  of the labeler/printer  10 , as shown in  FIGS. 1 and 2 . The receiving region  420  is defined by one or more interior walls  422  as shown in  FIG. 23 . Located along one or both of the interior walls  422  is one or more outwardly projecting guide member(s)  432  and a collection of electrical contacts  430 . The guide  432  is aligned and positioned so as to be slidably received in one or more recessed regions defined along the lower battery enclosure  32  of the labeler/printer  10 . The electrical contacts  430  of the charging cradle  400  are also appropriately positioned with respect to the guide  432  and the receiving region  420  of the charging cradle  400  so that upon engaging the lower battery enclosure  32  of the labeler/printer  10  with the receiving region  420  of the cradle  400 , the contacts  430  are in electrical communication with one or more electrical contacts  34  located along the battery enclosure  32  of the labeler/printer  10 , thus establishing electrical connection between the cradle  400  and the labeler/printer  10 . The electrical contacts  430  typically serve to provide for transfer of electrical current from the cradle  400  to the labeler/printer  10  such as during charging of one or more batteries onboard the labeler/printer  10 . The electrical contacts  430  may also serve to provide signal or information transfer between the cradle  400  and the labeler/printer  10 . 
     The charging cradle  400  also comprises one or more power and/or communication ports  440  accessible along the exterior of the housing  410 . Suitably, each cradle  400  includes an outwardly extending male port, such as port  440 , along one side of the housing  410  and another female port (not shown) along an oppositely directed side of the housing. This configuration enables multiple charging cradles  400  to be serially connected and/or daisy-chained to one another as described in greater detail herein. 
     The charging cradle  400  may also comprise an optional alignment member  450  and/or affixment base as depicted in  FIG. 23 . The member  450  suitably extends laterally outward from the housing  410  and serves to facilitate engagement with an adjacent component and/or promote securing the cradle  400  to an underlying support surface. One or more alignment surfaces  452  can be provided in the alignment member  450 , each suitably extending from a distal end of the member  450  to the housing  410  of the cradle  400 . The surfaces  452  are sized, shaped, and configured to slidably engage with corresponding receiving members provided in another component to be placed into electrical communication via the port  440 . Thus, although one or more cables (not shown) can be used to connect to port  440 , it is suitable to directly connect one port of a first cradle to another port of a second cradle (or other component). In this mode of connection, the alignment member  450  provides further physical engagement between the cradles and/or components. The alignment member  450  may also define one or more slotted regions  456 . Instead of slotted regions, one or more apertures could be used. Regardless, the slotted regions  456  and/or other apertures can receive fastening members which may serve to affix multiple charging cradles  400  to each other or to a controller  500  or to an underlying support or surface. 
     Each charging cradle  400  also suitably includes a collection of feet  460  for stably supporting the cradle  400 . 
     It will be understood that in no event is the invention limited to the particular charging cradle  400  described and illustrated in the accompanying figures. Instead, the invention includes a wide array of variant versions and designs. 
       FIG. 24  is a perspective view of an exemplary embodiment of a controller  500  in accordance with aspect of the present inventive subject matter. The controller comprises a housing  510 , one or more indicator lights  520 , and one or more feet  560  as generally depicted in  FIG. 24 . The controller also comprises various electronic processors and memory provisions and is configured to at least partially control the operation and charging of the labeler/printer  10 , and suitably also at least partially control the operation and charging of the cradle  400 . Furthermore, the controller  500  can also be configured to assist in the programming and transfer of operation instructions and other information between the labeler/printer  10 , the cradle  400 , and the controller  500 . 
       FIGS. 25 and 26  illustrate a combination  600  of one or more charging cradles  400  and a controller  500  in accordance with aspects of the present inventive subject matter. These figures are merely one possible configuration of a plurality of charging cradles  400 , each in electrical communication with one another via their corresponding ports (such as port  440  depicted in  FIG. 23 ) and also in electrical communication with a controller  500 . The controller  500  receives electrical power from a power cord (not shown) via a port  530  shown in  FIG. 26 . One or more accessory ports  532  may also be provided for signal or information transfer to or from the controller  500 . Suitably, each charging cradle  400  has a unique electronic address whereby the controller  500  controls the transfer of electrical power to each cradle  400  by appropriately selecting the cradle  400  via its address. Furthermore, one or more cradles  400  can be selected by the controller  500  to receive particular information, signals, and/or programming for the respective cradles and/or its corresponding labeler/printer engaged therein. 
     Another feature of the combination or system  600  of one or more cradles  400  and the controller  500  is that the controller  500  may also be configured to selectively and wirelessly communicate, e.g. transfer signals and/or information, with one or a collection of labeler/printers. For example, a controller  500  may wirelessly provide information to onboard memory provisions in one or more labeler/printers. 
     Yet another significant feature of the labeler/printer  10  is that the center of mass, and configuration and orientation of the lower face of the battery enclosure  32  are such that the labeler/printer  10  can be placed in an upright “standing” position in which the lower face of the battery enclosure  32  contacts a support surface. The center of mass is located over the lower face and relatively low such that the labeler/printer  10 , when placed in such position, is remarkably stable. 
     A further feature of the labeler/printer  10  is the provision of a smaller diameter or thickness grip in the location of the handle  24 . This improves user feel and workability, particularly for users having relatively small hands.
