USB Printer Class Device Replacement Service
This is a resident service on the computer. When the TM-C3500 is replaced for service or other
reason, this detects the printer connection and automatically changes the output printer of the
printer driver.ď€
This allows the printer to be replaced without changing settings in the application. (The printer
is not
replaced if a port is specified for the application output destination. The printer is only replaced if
the printer driver is specified.)
There is no need to change the USB serial number of the TM-C3500 before replacement.
