view full story

http://www.linuxquestions.org – I download Epson LQ-850 driver for Panasonic KX-P1121(as advice in forum) so the printer is working for some time then suddenly it start to print gibberish. So I removed all cups software then re-install it again, came out asking for keyword to connect to print server but can't go in after a while it just hang up. So has to re boot & start from an earlier kernel then the screen came out with the old printer of Panasonic still installed so try again to delete & re install the printer but can't find the Epson LQ-850 driver anymore. I am using Fedora 13. Help!!! (HowTos)
