USB Replacement Service
"USB Replacement Service" is a program that detects when a new printer is connected, changes the
properties information of the printer driver registered in Windows, and automatically changes the
output port. When this is installed as a resident program on the client computer, it is not necessary to
configure settings in the application, printer driver, or OS. However, printer settings are required.
When this procedure is used, the existing printer port will remain. For this reason, if the
printer port is specified as the application's output destination, use the procedure for
changing the printer's USB serial number to replace the printer.
❏ Preparation
• Install "USB Replacement Service" on the client computer.
• Printer setting file for existing printer
(Do not include the USB serial number setting.)
• DIP switch setting information for existing printer
❏ Printer replacement procedure
(1)
Remove the existing printer from the client computer.
(2)
Connect the new printer to the client computer and turn on the printer. "USB Replacement Service" will detect
the connection of the new printer and set a new printer port for the existing printer driver.
(3)
Configure the existing printer settings in the printer. Use the existing printer's printer setting file and the DIP
switch setting information. (Refer to
Matching the USB serial numbers of the printers
If the USB serial number of the new printer is the same as that of the existing printer, the printer can
be replaced without changing the application on the client computer or the printer driver settings.
However, printer settings are necessary. If a printer port is specified as the output destination of the
application, this method is recommended.
The USB serial number can be registered in the printer setting file, or edited in Printer Setting.
This explains the procedure for replacing the printer of the client computer by changing the new
printer's USB serial number on the administrator computer.
❏ Preparation
• Printer setting file for the existing printer
(Include the USB serial number setting.)
• DIP switch setting information for the existing printer
