     DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0015]    An Internet Based Digital Mail System Printer is conventionally formed by a base with a thermal printing module connected to this base. The Internet Based Digital Mail System Printer can also be comprised of a built in scale or interfaced external scale via a USB port that can weigh up to 70 lbs. Also, the said printer will be capable of sealing mailpieces automatically as the mailpiece is fed through the printer. The printer can be equipped with a built in touchscreen computer or interfaced with an external computer using USPS approved internet postage software via a USB port. Using the Internet Based Digital Mail System Printer, the operator determines the way each mailpiece/mail transfer card is to be processed (IE First Class, Priority, Express, etc.), places the mailpiece onto the internal/external scale for proper rate calculation, places the mailpieces/mail transfer cards onto the feeder hopper insuring the envelope flaps of the mailpieces that need sealing are placed in the sealer slot of the feed hopper. 
         [0016]    The printer is comprised of a feed photo sensor that when covered turns the main drive motor on to begin the process of conveying mailpieces/mail transfer cards through the printer. By placing a stack of mailpieces/mail transfer cards into the feeder hopper, the bottom piece is fed first automatically using a set of automatic adjusting separator fingers to insure each piece is fed one at a time. The mailpiece/mail transfer card will then pass over a second photo sensor that will send a signal to the printhead to print and feed the USPS approved label directly to the mailpiece/mail transfer card. A third photo sensor is used to stop the mailpiece/mail transfer card in the exact holding position by stopping the main drive motor. Once the USPS approved printed label is placed on the mailpiece/mail transfer card, the main drive motor will start again and feed the mailpiece/mail transfer card through a set of rollers to firmly press and adhere the USPS approved label onto the mailpiece/mail transfer card. After exiting the pressure rollers, the envelope will pass through the sealer unit which will wet the envelope flap if needed and then be conveyed through a second set of pressure rollers to apply the right amount of pressure, assuring that the envelope is sealed completely and ejected safely out of the printer. 
         [0017]    Referring now to the drawings, 
         [0018]      FIG. 1-4  are different views of what the outside of the printer can look like, but not limited to what the actual finished product will be. 
         [0019]      FIG. 1  shows the proposed outside view from the front of the printer. The printer will be comprised of a hinged front compartment door  40  which will give access to load the roll of labels. Also, the printer can include an integrated scale  43  which will have a capacity of up to 70 lb.s. The feeder will need a backstop  41  to help angle the stack of mailpieces. A sideguide  42  is used to keep the mailpiece straight as it enters through the separator unit. 
         [0020]      FIG. 2  shows the proposed outside view from the front of the printer. The printer can be comprised of a built in touchscreen  44  computer. Using the touchscreen option, the printer can be used as a stand alone system that will be operational with the use of a network jack to get internet access. A hinged front compartment door  40  will give access to load the roll of USPS approved labels. Also, the printer can include an integrated scale  43  which will have a capacity of up to 70 lb.s. The feeder will need a backstop  41  to help angle the stack of mailpieces. A side guide  42  is used to keep the mailpiece straight as it enters through the separator unit. 
         [0021]      FIG. 3  shows the side view of the printer. This angle shows the slot  46  for the mailpiece flap. When the mailpiece flap is placed into the slot  46 , the mailpiece flap will be sealed and closed as it exits the printer. 
         [0022]      FIG. 4  shows the proposed back view of the printer. The back of the printer can consist of the main power receptacle  47 , 2 or more, if applicable, USB ports  48  to interface with a computer, if necessary, and/or an external scale if the internal scale option isn&#39;t used. The printer will need to be comprised of a network jack  49  for internet access if the printer isn&#39;t interfaced with a computer. Each printer needs to have a serial tag sticker  50  with a unique serial number for tracking each printer. 
         [0023]      FIG. 5  schematically shows the front view of the linerless roll printer without covers. This shows the path the mailpieces/mail transfer cards  1  as it is fed through the printer. As you can see, the stack  2  of mailpieces is placed onto the feed hopper covering the first photo sensor  3  which in turn starts the main drive motor. As the bottom mailpiece  1  is being fed into the printer by the feed drive belt  55 , the separator fingers  4  hold back on the rest of the stack  2  of mailpieces to insure one mailpiece  1  enters the printer at a time. After the mailpiece  1  passes under the separator fingers  4 , a second sensor  5  is covered which signals the computer to begin printing the USPS approved label  9 . The roll  6  of linerless labels are fed down the path through two sets of non-adherent rollers  7 , 12 . Between these sets of rollers  7 , 12  is a cutter/perforator bar  8 . This cutter/perforator bar  8  can cut/tear the label  9  at the perforation to insure the correct length of the label  9 . Once the label  9  has been cut/torn, the label  9  will enter the printhead unit  10  to be printed and then transferred to the mailpiece/mail transfer card  1  using a deflector guide strap  19  to help position the label  9  onto the mailpiece  1 . A photo sensor  11  is used at the entrance of the printhead unit  10  to insure the label  9  is in the correct position to be printed. The label path  13  is coated with a non-adherent material, where applicable, to insure the label  9  passes through the path cleanly. The mailpiece then arrives at the third photo sensor  14  which stops the mailpiece  1  to apply the label  9  onto the mailpiece  1 . The photo sensor  15  at the exit of the printhead unit  10  signals the base that the label  9  has exited the printhead unit  10  and to turn the main drive motor on. Once the main drive motor is turned back on, the mailpiece  1  is fed through the first set of pressure rollers  16  adhering the label  9  to the mailpiece  1 . The mailpiece  1  is then fed through the sealer unit  17  to seal the mailpiece  1  if applicable and then through the second set of pressure rollers  18  to help press and seal the mailpiece  1  as it exits the printer. 
         [0024]      FIG. 6  schematically shows the back view of the printer&#39;s belt drive unit of the linerless type. This displays the belt drive direction. The main drive belt  25  turns in a counter clockwise rotation when viewing the printer from the back. The main drive belt  25  uses a slotted/adjustable idler roller  26  to tighten the belt to the right tension. Also shown are the cutter drive gears  27 , 28 , 29 , 30 . A cutter drive gear motor  31  rotates the middle drive gear  28  in a clockwise rotation. Once the cutter exit gear  29  rotates one full turn, the cutter activation photo sensor  32  sends a signal to the cutter/perforator bar  8  to activate and cut/tear the label to the right length. The label is then fed into the printhead unit passing over a photo sensor  11  that relays a signal to the printhead to start printing the USPS approved thermal label. After the label exits the printhead unit and the printhead exit photo sensor  15  is unblocked, the main drive motor  33  of the base unit will start to fed the mailpiece/mail transfer card. The label path is coated with a non-adherent material, where applicable, to insure the label passes through the path cleanly. 
         [0025]      FIG. 7  schematically shows the front the lined roll printer without covers. This shows the path the mailpieces/mail transfer cards  1  as it is fed through the printer. As you can see, the stack  2  of mailpieces is placed onto the feed hopper covering the first photo sensor  3  which in turn starts the main drive motor. As the bottom mailpiece  1  is being fed into the printer by the feed drive belt  55 , the separator fingers  4  hold back on the rest of the stack  2  of mailpieces to insure one mailpiece  1  enters the printer at a time. After the mailpiece  1  passes under the separator fingers  4 , a second photo sensor  14  is covered which signals the computer to begin printing the USPS approved label  20 . The printhead unit  10  is controlled by two photo sensors  11 , 15  that insure the label  20  is in the correct position to be printed. The printhead motor is reversible to allow the label to be advanced far enough past the peel bar  21  to be placed on the mailpiece/mail transfer card  1 . This is accomplished by the two photo sensors  11 , 15 . The photo sensor  15  at the exit of the printhead unit  10  signals the base that the label  20  has exited the printhead unit  10  and to turn the main drive motor on. The excess lined backing/carrier  22  is neatly wound up on the waste collector shaft  23 . Once the main drive motor is turned back on, the mailpiece  1  is fed through the first set of pressure rollers  16  adhering the label  20  to the mailpiece  1 . The mailpiece  1  is then fed through the sealer unit  17  to seal the mailpiece  1  if applicable and then through the second set of pressure rollers  18  to help press and seal the mailpiece  1  as it exits the printer. 
         [0026]      FIG. 8  schematically shows the back view of the printer&#39;s belt drive unit of the lined type. This displays the belt drive direction. The main drive belt  25  turns in a counter clockwise rotation when viewing the printer from the back. The main drive belt  25  uses a slotted/adjustable idler roller  26  to tighten the belt to the right tension. Also shown is the waste collector shaft o-ring belt  37 . As the printhead prints the USPS approved thermal label, the waste collector o-ring belt  37  turns to wind up the excess backing material on the waste collector shaft. After the label exits the printhead unit and the printhead exit photo sensor is unblocked, the main drive motor  33  of the base unit will start to feed the next mailpiece/mail transfer card.
