NOTE 1 - Selecting USB I/O Port
When selecting USB or Serial as the interface & no connection is made, the
problem lies with the PC I/O ports. Different messages may appear on screen,
for instance, "All USB or Serial interfaces in use, please delete any unused
USB or Serial printers and make sure your printer is plugged in and turned on",
etc. PC maintenance needs to be performed. Some PC corrective actions that
can be performed by the user:
1. If a “line” printer is also attached to the terminal, go into the printer
properties & change the port to USB002. The “line” printer likely has
USB001. Since the printer has moved around between ports it could even
be USB003 or USB004.
2. If all USB or serial I/O ports are shown as “occupied” & devices are actually
connected, then a port extender may be needed
3. Run the installer again after plugging the POS receipt printer into another
USB port.
4. If problem persists see NOTE 3 below.
NOTE 2 - Printer prints, Cash Drawer Does Not Open
1. Determine if the system application program software (“SAPS”)
communicates with the printer/drawer driver by Driver Based
Communications or Direct Based Communications.
2. Driver Based Communications is handled automatically through the printer
driver which controls the opening the cash drawer. Therefore, this method
should not be causing the cash drawer to not open.
3. Direct Based Communications SAPS has Drawer Open Codes that are
programmed into the SAPS to allow the drawer to function. These Codes
are in the format expected by the system application program. The Codes
need to be changed.
a. Manually enter the Cash Drawer Open Codes.
i.
Try values from “Codes” column.
ii.
If values from Codes column do not work, try “Alternate Codes.
b. If the Codes are fixed contact the software vendor to request that the
SAPS be changed to allow manual entry of the Printer/Cash Drawer
Open Codes.
