9.2 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: Changing Cable Connections in a Running System
When connecting the printer to the machine, do not forget that only USB
devices can be plugged in or unplugged during operation. To avoid
damaging your system or printer, shut down the system before changing
any connections that are not USB.
