, see if SX-218 works for you. Mostly linux drivers work for several versions.
Generally installation of printers in Gnu/Linuxes is via CUPS (Common Unix Printing System). Be sure your printer is plugged 'ON'. Launch a web browser 'Firefox' and put an address: 'http://127.0.0.1:631' --note the colon between the IP and port number. Being there in the CUPS goto Administration -> Install New Printer -> blah blah easy to follow instructions: I am certain the driver for SX-218 shall be there available.
Hope this helps. Good luck.
