    The accumulator and tare memory registers are essential to the useful operation of the GS8920 Ticket Printer. While the GS8920 has 50 accumulator registers and 50 tare registers, only one of each is kept open at any one time. The GS8920 uses only the active accumulator or active tare register for its ticket operations.

  • Page 50 In this example the gross weight is from the digital weight indicator and the tare weight from one of the GS8920’s 50 tare registers. The net weight is computed by the GS8920 Ticket Printer and a ticket is printed. The weights are added to the active accumulator.
  • Page 51 The net weight is computed by the GS8920 Ticket Printer and a ticket is printed. In addition, the GS8920’s Item Entry facility is active and so the number of items as well as the price per unit weight were entered.
  • Page 52 This can be accomplished using the GS8920’s summation capability. The truck is fully laden and its tare weight will be entered via the GS8920’s keyboard from information printed on the side of the truck. The ticket printout setup is the same as the preceding example.

  • Page 76 2 .7 Ticket Lay out. The drawing below shows the area in which the GS8920 can be made to print for right of page justification printing with the ticket being drawn into the printer as the ticket is printed. This results in a printout which may have the lines left or right justified but which appears on a wide ticket as either somewhere in the middle or down the right side.
  • Page 77 GS8920 automatically and correctly locates the printing in accordance with all the other location parameters. The range of printout forms available from the GS8920 Ticket Printer is very extensive. Sample printouts of the ACTUAL applications setup should therefore be obtained before printing standard ticket stationery.
  • Page 78 The data is transmitted at the same time as the GS8920 generates a printout on its printer mechanism. Since the data to be printed on the GS8920’s mechanism may be buffered with all the data sent first to the remote printer, and since handshake lines and/or codes are not used, the remote printer must have a buffer capable of receiving all of the data.
  • Page 79 The GS8920 Ticket Printer automatically detects the serial output option P1. No changes are required to any of the GS8920’s digital setup parameters upon installation of Option P1, but note, the baud rate and parity settings for the serial input to the GS8920 Ticket Printer will also apply to the GS8920’s serial output.
