Urgent printer help?!?

[skinner05]

Ive got a printer at home, it is a tally genicom 8108n. For some reason, one day it will print fine and the next day it wont print at all, it doesnt respond when a document is sent to print.Im led to believe it is something to do with the ports and it being knocked off its port if it switched off at a bad time etc. Does anyone have any help suggestions. Would be extremely appreciated.

cheers
