Canon MP145 not working as print Server

view story

http://forums.opensuse.org – I have MP145 on my LAN with openSUSE 11.2 as the OS both on client and print server. I manage to print and using scanner on my print server but failed to print from my client, although test print page on CUPS web interface is working well. FYI i'm using driver from canon asia for this printer. Already try to upgrade CUPS and it's library but still not working. trying to use Epson R 230 either but with no luck, does anyone experience this? and how to solve it? (Distributions)
