     BACKGROUND 
     Monitors and printers are used while individually connected to hosts, for example, computers. Monitors are generally used on desks. 
     To secure accessibility, desktop printers may be put on desks and used. General desktop printers have footprints that are greater than the maximum printable size of paper. Therefore, since general desktop printers occupy large spaces on desks, it is not easy to put general desktop printers on desks. Since a large desk is needed to put both a desktop printer and a monitor on a desk, it may not be easy to efficiently use a given space for home or small office/home office (SOHO). Although a desktop printer may be used by putting it on a separate desk near a desk on which a monitor is put, accessibility to the printer may deteriorate in this case.

     DETAILED DESCRIPTION 
       FIG.  1    is a perspective view of an example of a printer.  FIG.  2    is a longitudinal sectional view of the example of the printer shown in  FIG.  1   . Referring to  FIGS.  1  and  2   , a printer  1  of the example is a vertical type printer. The printer  1  may include: a main body  10  accommodating a printing portion  100 , which prints an image onto a print medium P, and including an outlet  18  through which the print medium P is discharged, the print medium P being transported along a vertically oriented printing path  19 ; a stand  20  supporting the main body  10  such that the main body  10  is rotatable in a front-rear direction R 1 ; a discharge guide  30  mounted to the main body  10  to be rotatable in a vertical direction R 2  and guiding the print medium P forward, the print medium P being discharged from the outlet  18 ; and a first elastic member  40  applying an elastic force to the discharge guide  30  in a direction in which the discharge guide  30  is rotated upward. 
     The print medium P is transported from an upper portion  12  to a lower portion  13  of the main body  10 . For example, a feeding slot  12 - 1  through which the print medium P is fed may be provided to the upper portion  12  of the main body  10 . The outlet  18  through which the printing-completed print medium P is discharged may be provided to the lower portion  13  of the main body  10 . Although not shown in the drawings, the outlet  18  does not necessarily have to be provided to the lower portion  13  and may be provided to a lower region of a front portion  11  of the main body  10 . 
     The printing portion  100  of the example prints the image onto the print medium P in an electrophotographic manner. The printing portion  100  may include a developing device  110  (development cartridge) that is replaceable, an exposure device  120 , a transfer unit  130 , and a fuser  140 . The developing device  110  includes a photosensitive drum  111  and develops an electrostatic latent image into a visual toner image by supplying a toner accommodated inside the developing device  110  to the electrostatic latent image formed on the photosensitive drum  111 . 
     The photosensitive drum  111  is an example of a photoconductor having an electrostatic latent image formed on a surface thereof, and may include a conductive metal pipe and a photosensitive layer on an outer circumference of the conductive metal pipe. The developing device  110  may include a developing roller  112 . The developing roller  112  supplies the toner inside the developing device  110  to the photosensitive drum  111 . A developing bias voltage may be applied to the developing roller  112 . A regulating member, which is not shown, regulates, an amount of the toner supplied by the developing roller  112  to a development region in which the photosensitive drum  111  and the developing roller  112  face each other. The developing device  110  of the example employs a one-component developing manner. The developing roller  112  may be rotated in contact with the photosensitive drum  111 . The developing roller  112  may be rotated while located apart from the photosensitive drum  111  by tens to hundreds of micrometers. The developing device  110  may include a supplying roller  113  attaching the toner onto a surface of the developing roller  112 . A supply bias voltage may be applied to the supplying roller  113 . The developing device  110  may include an agitator (not shown). The agitator may triboelectrically charge the toner inside the developing device  110  by agitating the toner. The agitator may transport the toner toward the supplying roller  113 . A charging roller  114  is an example of a charger charging the photosensitive drum  111  such that the photosensitive drum  111  has a uniform surface electric potential. A charging brush, a corona charger, or the like may be used instead of the charging roller  114 . Although not shown in the drawings, the developing device  110  may include a cleaning member removing foreign substances remaining on the surface of the photosensitive drum  111  after a transfer process. 
     The developing device  110  is a consumable that is replaced when the toner accommodated inside the developing device  110  is exhausted. The developing device  110  may be provided in the form of a development cartridge including the components described above. 
     The exposure device  120  forms the electrostatic latent image on the photosensitive drum  111  by irradiating the photosensitive drum  111  with light modulated in correspondence with image information. As the exposure device  120 , a laser scanning unit (LSU) using a laser diode as a light source, a light emitting diode (LED) exposure device using an LED as a light source, or the like may be used. 
     The transfer unit  130  transfers the toner image formed on the photosensitive drum  111  onto the print medium P. For example, the transfer unit  130  may include a transfer roller that is rotated while facing the photosensitive drum  111 . A transfer bias voltage for transferring the toner image onto the print medium P is applied to the transfer roller. A corona transfer unit or a pin scorotron type transfer unit may be used instead of the transfer roller. 
     The fuser  140  applies heat and pressure to the toner image transferred onto the print medium P, thereby fusing the toner image on the print medium P. As an example, the fuser  140  may include a heating roller and a pressing roller, which are rotated while engaged with each other to form a fusing nip. The heating roller may be heated by a heat source. 
     According to the configuration described above, the exposure device  120  forms the electrostatic latent image by scanning the light modulated in correspondence with the image information onto the photosensitive drum  111 . The developing device  110  forms the visual toner image on the surface of the photosensitive drum  111  by supplying the toner onto the electrostatic latent image formed on the photosensitive drum  111 . The print medium P loaded in a loading portion  160  is fed, one by one, to the vertically extending printing path  19 . The toner image maintained on the photosensitive drum  111  due to an electrostatic force is transferred onto the print medium P by the transfer unit  130 . When the print medium P passes through the fuser  140 , the toner image is fused on the print medium P by heat and pressure. The fusing-completed print medium P is discharged through the outlet  18 . 
     Although an example of the printing portion  100  of an electrophotographic type has been described, the printing portion  100  may print the image onto the print medium P in another printing manner. For example, the printing portion  100  may print the image onto the print medium P in various printing manners such as an inkjet manner, a thermal transfer manner, and the like.  FIG.  3    is a longitudinal sectional view of an example of the printer  1  in which the printing portion  100  of an inkjet type is applied. Referring to  FIG.  3   , the printing portion  100  includes an inkjet cartridge  170 . The inkjet cartridge  170  may include an inkjet head ejecting ink, and an ink tank accommodating the ink. The ink tank may be separated from the inkjet cartridge  170 , and may be connected to the inkjet cartridge  170  by a connecting member such as a pipe or the like and thus supply the ink to the inkjet cartridge  170 . The inkjet cartridge  170  may be a shuttle type inkjet cartridge ejecting the ink onto the print medium P that is moved in a sub-scanning direction while reciprocally moved in a main scanning direction. The inkjet cartridge  170  may be an array inkjet cartridge having a length which corresponds to a width of the print medium P in the main scanning direction, the array inkjet cartridge ejecting the ink onto the print medium P that is moved in the sub-scanning direction while being at fixed position without movement in the main scanning direction. Use of the array inkjet cartridge enables high-speed printing as compared with use of the shuttle type inkjet head. The inkjet cartridge  170  may be, for example, a monochrome inkjet cartridge ejecting ink of a black color. The inkjet cartridge  170  may be, for example, a color inkjet cartridge ejecting inks of black (K), yellow (Y), magenta (M), and cyan (C) colors. The inkjet cartridge  170  may be replaced once the end of the lifetime thereof has been reached. 
     The print medium P drawn from the loading portion  160  by a pickup roller  150  is transported along the vertically extending printing path  19 , and is supported by a platen  180  to maintain a predetermined gap from the inkjet cartridge  170 . The inkjet cartridge  170  ejects the ink onto the print medium P, thereby printing the image. The printing-completed print medium P is discharged through the outlet  18 . 
     Referring to  FIG.  1   , the main body  10  has a width W, a height H, and a depth D. The depth D may be less than the width W. According to this configuration, a footprint of the printer  1  is less than a maximum printable size of the print medium P. Therefore, it is easy to put the printer  1 , together with a monitor, on a desk, and user accessibility to the printer  1  may be secured. The depth D may be less than the height H. 
     The printer  1  of the example may be useful when used together with a monitor.  FIG.  4    is a side view illustrating an example of the printer  1  used together with a monitor. Referring to  FIG.  4   , the printer  1  is located behind a monitor  2 . Here, the discharge guide  30  is maintained in contact with a lower edge  2 - 1  of the monitor  2  due to the elastic force of the first elastic member  40 . The monitor  2  may be tilted backward by a user. Since the main body  10  is supported by the stand  20  to be rotatable in the front-rear direction R 1 , the main body  10  may also be tilted backward with respect to the stand  20  in accordance with a degree by which the monitor  2  is tilted. Here, since the discharge guide  30  is elastically biased to be rotated upward around a hinge  31  by the first elastic member  40 , the discharge guide  30  may be maintained in contact with the lower edge  2 - 1  of the monitor  2 . When the printing-completed print medium P is output from the printer  1 , the print medium P seems to be output forward from the lower edge  2 - 1  of the monitor  2  from a viewpoint of a user in front of the monitor  2 . 
     Such a structure may be useful to provide a special use experience to the user. For example, in the case where there is a request to print an electronic document, when the electronic document is printed by the printer  1  and output as an actual document, a user experience, in which a preview image of the electronic document requested to be printed disappears from a screen of the monitor  2  in synchronization with the output of the actual document by the printer  1 , may be provided. 
       FIG.  5    is a diagram illustrating an example of a user experience in which a preview image of a document disappears from a screen of a monitor in synchronization with document output of a printer. Referring to  FIG.  5   , when a print command for the electronic document is issued to the printer  1  by a host, the preview image of the electronic document may be provided onto the screen of the monitor  2 . When the actual document starts to be output from the printer  1 , the preview image may also start to disappear from the screen of the monitor  2 , and when the output of the actual document is completed, the preview image may also completely disappear from the screen of the monitor  2 . A path along which the preview image is moved on the screen of the monitor  2  may overlap a path along which the actual document is output from the printer  1 , and a sliding direction of the preview image may coincide with a direction in which the actual document is output starting from a lower end of the actual document. For example, as the preview image is moved, on the screen of the monitor  2 , toward the lower edge  2 - 1 , the preview image may gradually disappear from the screen. A process in which the preview image disappears toward the lower edge  2 - 1  of the monitor  2  may be synchronized with a process in which the printing-completed actual document is output from the printer  1 . That is, a formation process of the preview image may be synchronized with a print process such that, when a lower edge of the preview image on the screen disappears to the lower edge  2 - 1  of the monitor  2 , a leading end of the actual document output along the discharge guide  30  appears at the lower edge  2 - 1  of the monitor  2 . According to this control, an effect by which the electronic document on the screen seems to come out as the actual document may be provided, thereby improving a user experience regarding the print process. 
     Referring again to  FIG.  1   , a door  15  that may be opened and closed may be provided to a side portion  14  of the main body  10  such that a consumable of the printing portion  100  may be replaced. According to this configuration, the door  15  for replacing the consumable may be arranged in the side portion  14  that is easily accessible in an environment in which the printer  1  is located behind the monitor  2 , thereby improving user convenience. As an example, the door  15  may be rotatably provided to the side portion  14  of the main body  10 . As an example, the door  15  may be separably combined with the side portion  14  of the main body  10 . The consumable may be, for example, a development cartridge  110 . The consumable may be, for example, an inkjet cartridge  170 . 
     The printer  1  may have a structure stably guiding the print medium P, which is discharged through the outlet  18 , to the discharge guide  30  as the discharge guide  30  is rotated in the vertical direction.  FIG.  6    is a detail view of a portion A of  FIG.  2   . Referring to  FIG.  6   , a variable path member  190  is shown, the variable path member  190  forming a transport path  191  of the print medium P between the outlet  18  and the discharge guide  30  while being rotated in conjunction with the rotation of the discharge guide  30 . The variable path member  190  is mounted in the main body  10  to be rotatable around a hinge  192 . As an example of a structure for combining the rotation of the discharge guide  30  with the rotation of the variable path member  190 , a first interfering portion  32  is provided to the discharge guide  30 , and a second interfering portion  193  contacting the first interfering portion  32  is provided to the variable path member  190 . A second elastic member  194  applies an elastic force to the variable path member  190  such that the second interfering portion  193  is rotated in a direction in which the second interfering portion  193  contacts the first interfering portion  32 . 
     According to this configuration, when the discharge guide  30  is rotated upward around the hinge  31 , the first interfering portion  32  pushes the second interfering portion  193 , and thus, the variable path member  190  is rotated upward around the hinge  192 . When the discharge guide  30  is rotated downward around the hinge  31 , the variable path member  190  is rotated downward around the hinge  192  due to the elastic force of the second elastic member  194  such that the second interfering portion  193  is maintained in contact with the first interfering portion  32 . Therefore, even though a tilt angle of the discharge guide  30  with respect to the main body  10  is changed, the print medium P discharged through the outlet  18  may be stably guided to the discharge guide  30  along the transport path  191  provided by the variable path member  190 . 
     The printer  1  may be rotated with respect to the stand  20  in conjunction with a change in a tilt angle of the monitor  2 .  FIG.  7    is a partial exploded perspective view of an example of the printer  1 . Referring to  FIG.  7   , a first combining structure  200  is provided to the front portion  11  of the main body  10 . The first combining structure  200  is a structure with which an external device may be combined. The first combining structure  200  may include, for example, one or more screw fastening portions  201  (screw holes). The number of screw fastening portions  201  and an interval therebetween are not limited. For example, the number of screw fastening portions  201  and the interval therebetween may comply with the VESA mount standards. According to this configuration, the external device satisfying the VESA mount standards may be directly combined with the first combining structure  200 . In addition, the external device may be combined with the first combining structure  200  via an adaptor satisfying the VESA mount standards. 
     It may be optional to use the first combining structure  200 . For this, the printer  1  may include a first cover  210  that is removable and covers the first combining structure  200  such that the first combining structure  200  is not exposed. The first cover  210  may be combined with the front portion  11  to cover the first combining structure  200 . For example, the first cover  210  may be fixed to the front portion  11  such that the first cover  210  is combined with and thus covers the first combining structure  200 . As another example, the first cover  210  may be fixed to the front portion  11  by a snap-fit structure to cover the first combining structure  200 . According to this configuration, the first combining structure  200  may not be exposed outside thereof when not used, thereby improving appearance quality of the printer  1 . After the first cover  210  is removed, the external device may be combined with the first combining structure  200 . 
     In the printer  1  of the example, an interlocking member  230  is combined, as the external device, with the first combining structure  200  such that the main body  10  may be rotated with respect to the stand  20  in conjunction with the change in the tilt angle of the monitor  2  located in front of the printer  1 . The interlocking member  230  may include: a bracket  231  having a structure combinable with the first combining structure  200 ; and at least one supporting arm protruding forward from the bracket  231  and elastically rotatable around a hinge  232  which is spaced apart from a rotation shaft  21  of the main body  10  in the vertical direction, that is, in a height direction. In the example, two supporting arms  233   a  and  233   b  are rotatably supported by the bracket  231 . The two supporting arms  233   a  and  233   b  may be symmetrically located with reference to the rotation shaft  21  in the vertical direction, that is, in the height direction. A third elastic member  234  applies an elastic force to a supporting arm  233  such that the supporting arm  233  is rotated in a direction in which a leading end  233 - 1  of the supporting arm  233  faces forward. As an example, the third elastic member  234  may be a torsion coil spring including two arms respectively supported by the supporting arm  233  and the bracket  231 . A roller  235  that is rotatable may be provided to the leading end  233 - 1  of the supporting arm  233 . The bracket  231  may include, for example, mount holes  231 - 1  compliant with the VESA mount standards. By fastening screws to the screw fastening portions  201  of the first combining structure  200  through the mount holes  231 - 1 , the bracket  231  may be combined with the first combining structure  200 . 
       FIG.  8    is a side view illustrating that the main body  10  is rotated in conjunction with the change in the tilt angle of the monitor  2 . Referring to  FIG.  8   , the printer  1  is located behind the monitor  2 . Here, the discharge guide  30  is maintained in contact with the lower edge  2 - 1  of the monitor  2  due to the elastic force of the first elastic member  40 . The supporting arms  233   a  and  233   b  are maintained while the leading end  233 - 1  of each of the supporting arms  233   a  and  233   b  is in contact with a rear surface  2 - 2  of the monitor  2  due to the elastic force of the third elastic member  234 . In the case where the roller  235  is provided, the roller  235  contacts the rear surface  2 - 2  of the monitor  2 . 
     The monitor  2  may be tilted backward by a user. Then, the supporting arm  233   a  is pushed backward by the monitor  2 , and the main body  10  is rotated backward around the rotation shaft  21  with respect to the stand  20 . Here, the discharge guide  30  may be maintained in contact with the lower edge  2 - 1  of the monitor  2  due to the elastic force of the first elastic member  40 . When the monitor  2  returns to an original state thereof, the supporting arm  233   b  is pushed backward by the monitor  2 , and the main body  10  is rotated around the rotation shaft  21  with respect to the stand  20  and thus returns to an original state thereof. The supporting arms  233   a  and  233   b  may be maintained in contact with the rear surface  2 - 2  of the monitor  2  due to the elastic force of the third elastic member  234 . In the case where the roller  235  that is rotatable is provided to the leading end  233 - 1  of each of the supporting arms  233   a  and  233   b , since the rear surface  2 - 2  of the monitor  2  is in rolling contact with the roller  235 , the main body  10  may be softly rotated in conjunction with the change in the tilt angle of the monitor  2 . 
     As such, according to a structure in which the printer  1  has a tilt angle in conjunction with the tilt angle of the monitor  2 , and in which the discharge guide  30  is maintained in contact with the lower edge  2 - 1  of the monitor  2 , when the electronic document described with reference to  FIG.  5    is printed by the printer  1  and output as the actual document, a user experience, in which the preview image of the electronic document requested to be printed disappears from the screen of the monitor  2  in synchronization with the output of the actual document by the printer  1 , may be provided. 
     The external device may be the monitor  2 . That is, the monitor  2  may be combined with the first combining structure  200 . In this way, a monitor-integrated printer may be implemented.  FIG.  9    is an exploded perspective view of an example of a monitor-integrated printer. Referring to  FIG.  9   , the first combining structure  200  is provided to the front portion  11  of the main body  10 . The first combining structure  200  may be exposed, for example, by removing the first cover  210  ( FIG.  7   ). The monitor  2  may be combined with the first combining structure  200 . 
     In an example, the monitor  2  may be combined with the first combining structure  200  by an adaptor bracket. The adaptor bracket may include a first adaptor bracket  240 , and a second adaptor bracket  250  that is combined with the monitor  2 , for example, the rear surface  2 - 2  of the monitor  2 . A first connecting portion  241  may be provided to the first adaptor bracket  240 , and a second connecting portion  251  combined with the first connecting portion  241  in a male-female combining manner may be provided to the second adaptor bracket  250 . The first connecting portion  241  may be detachably combined with the second connecting portion  251  in the vertical direction. As an example, the first connecting portion  241  may have a slot shape that is cut open in the vertical direction, and the second connecting portion  251  may have a clip shape that extends in the vertical direction to be insertable into the first connecting portion  241  of a slot shape in the vertical direction. 
     According to this configuration, since the stand  20  of the printer  1  may function as a stand  2 - 3  ( FIG.  4   ) of the monitor  2 , the stand  2 - 3  for the monitor  2  is not separately needed. When there is the stand  2 - 3  for the monitor  2 , the printer  1  needs to be located at a position allowing no interference between the discharge guide  30  and the stand  2 - 3 , that is, at a position biased toward one side in a width direction of the monitor  2  with respect to the stand  2 - 3 . According to the example, since there is no interference between the print medium P output from the discharge guide  30  and the stand  2 - 3  of the monitor  2  due to the absence of the stand  2 - 3 , the printer  1  may be mounted at various positions in the width direction of the monitor  2 , for example, at a central position in the width direction of the monitor  2 . 
     Since the monitor  2  is removable, the monitor  2  of various sizes may be combined with the printer  1 , as needed. The discharge guide  30  may be naturally brought into contact with the lower edge  2 - 1  by the elastic force of the first elastic member  40  when the monitor  2  is combined with the main body  10 . Therefore, when the electronic document described with reference to  FIG.  5    is printed by the printer  1  and output as the actual document, a user experience, in which the preview image of the electronic document requested to be printed disappears from the screen of the monitor  2  in synchronization with the output of the actual document by the printer  1 , may be provided. 
     In some cases, the printer  1  may be used as a stand-alone printer by removing the monitor  2  and combining the first cover  210  with the front portion  11 . 
       FIG.  10    is an exploded perspective view of an example of a monitor-integrated printer. Referring to  FIG.  10   , in the monitor-integrated printer in the example, the monitor  2  is combined with the front portion  11  of the main body  10 , and the stand  20  is combined with a rear portion  16  of the main body  10 . 
     The structure shown in  FIG.  9    may be applied as a structure in which the monitor  2  is combined with the front portion  11  of the main body  10 . In an example, the monitor  2  may be combined with the front portion  11  of the main body  10  by an adaptor bracket. The adaptor bracket may include: the first adaptor bracket  240  combined with the front portion  11  of the main body  10  and including the first connecting portion  241 ; and the second adaptor bracket  250  combined with the monitor  2  and including the second connecting portion  251  that is detachably combined with the first connecting portion  241 . The first connecting portion  241  may be removably combined with the second connecting portion  251  in the vertical direction. 
     The stand  20  is combined with the rear portion  16  of the main body  10 . The stand  20  includes the rotation shaft  21  supporting the main body  10  such that the main body  10  is rotatable in the front-rear direction. A second combining structure  260  may be provided to the rear portion  16  of the main body  10 . The second combining structure  260  may include, for example, one or more screw fastening portions  261  (screw holes). The number of screw fastening portions  261  and an interval therebetween are not limited. For example, the number of screw fastening portions  261  and the interval therebetween may comply with the VESA mount standards. According to this configuration, the stand  20  satisfying the VESA mount standards may be directly combined with the second combining structure  260 . In addition, the stand  20  may be combined with the second combining structure  260  via an adaptor satisfying the VESA mount standards. 
     It may be optional to use the second combining structure  260 . For example, the stand  20  may be combined with the side portion  14  of the main body  10 , as shown in  FIG.  9   . As such, when the second combining structure  260  is not used, the printer  1  may include a second cover  270  that is removable and covers the second combining structure  260  such that the second combining structure  260  is not exposed. The second cover  270  may be combined with the rear portion  16  to cover the second combining structure  260 . For example, the second cover  270  may be fixed to the rear portion  16  such that the second cover  270  is combined with and thus covers the second combining structure  260 . As another example, the second cover  270  may be fixed to the rear portion  16  by a snap-fit structure to cover the second combining structure  260 . According to this configuration, the second combining structure  260  may not be exposed outside thereof when not used, thereby improving the appearance quality of the printer  1 . After the second cover  270  is removed, the external device such as the stand  20  or the like may be combined with the second combining structure  260 . 
     According to this configuration, since the stand  20  of the printer  1  may function as the stand  2 - 3  of the monitor  2 , the separate stand  2 - 3  of the monitor  2  is not needed. When there is the stand  2 - 3  for the monitor  2 , the printer  1  needs to be located at a position allowing no interference between the discharge guide  30  and the stand  2 - 3 , that is, at a position biased toward one side in the width direction of the monitor  2  with respect to the stand  2 - 3 . According to the example, since there is no interference between the print medium P output from the discharge guide  30  and the stand  2 - 3  of the monitor  2  due to the absence of the stand  2 - 3 , the printer  1  may be mounted at various positions in the width direction of the monitor  2 , for example, at a central position in the width direction of the monitor  2 . Since the monitor  2  is removable, the monitor  2  of various sizes may be combined with the printer  1 , as needed. The discharge guide  30  may be naturally brought into contact with the lower edge  2 - 1  by the elastic force of the first elastic member  40  when the monitor  2  is combined with the main body  10 . Therefore, when the electronic document described with reference to  FIG.  5    is printed by the printer  1  and output as the actual document, a user experience, in which the preview image of the electronic document requested to be printed disappears from the screen of the monitor  2  in synchronization with the output of the actual document by the printer  1 , may be provided. In some cases, the monitor  2  may be removed, and the first cover  210  may be combined with the front portion  11 . In addition, since the stand  20  is mounted to the rear portion  16  of the main body  10 , it is easy to mount the door  15  for replacing the consumable to the side portion  14  of the main body  10 . 
     While examples have been described with reference to the drawings, it will be understood that these are examples, and that various changes and equivalent examples may be made therefrom without departing from the spirit and scope as defined by the following claims. Therefore, the scope of the disclosure should be defined by the accompanying claims.
