Check The Pc Connection - DataCard SP55 Plus Printer Manual

Check the PC connection

The printer and PC are connected when the printer is
set up. Before beginning card processing, make sure the
connection is complete.
The USB data cable should be connected to a USB port
on the PC and to the USB data port on the printer.
The printer can be connected in these other ways:
Through a direct network connection, where the
printer is connected to a network (using a print
server) and the PC is connected to the same
network.
As a shared printer, where the printer is connected
to another PC on the network and the user's PC is
connected to the network.
See SP Info Central for more information about
connecting the printer.
