[Printing-user-general] Problem installing a networked printer

Hello all,
I have a printer (Lexmark E232) installed on a debian server (CUPS), the
printer is published.
Now i have my personal laptop on wich i got Ubuntu installed with CUPS, i would
like to add the printer, giving it's URI
(ipp://printerServerHost:631/printers/lexmarkPrinter), it will ask for the
driver in next step, and that's what i wont get.
How to install it as a postscript printer, my lexmark is installed using its
driver on the server and i dont need to get the driver every time i want to use
it from a client computer.
Anyone can help me please ?
thanks
