Problem installing a networked printer

[Fourat Zouari]

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
