19.2 Methods and Protocols for Connecting Printers
There are various possibilities for connecting a printer to the
system. The configuration of the CUPS print system does not
distinguish between a local printer and a printer connected to the system
over the network.
In Linux, local printers must be connected as described in the
manual of the printer manufacturer. CUPS supports serial,
USB, parallel, and SCSI
connections. For more information about the printer connection,
read the article CUPS in
a Nutshell in the Support Database at https://en.opensuse.org/SDB:CUPS_in_a_Nutshell.
WARNING: Cable Connection to the Machine
When connecting the printer to the machine, do not forget that only
USB devices can be plugged in or unplugged during operation. The system
should be shut down before changing other kinds of connections.
