LinuxQuestions.org - Update Gutenprint drivers in CUPS

I'm trying to setup a print server on Debian Lenny. This dedicated server is connected to an USB printer (Epson Stylus Office BX300f).

I've successfully installed cups and the guttenprint drivers from the repositories but then realized that I needed to upgrade the printer drivers if I wanted to get support for my USB printer. Thus, I built and installed the latest version of Guttenprint (5.2.6) from the sources but this procedure has not added any new driver (ppd files) into cups. I've read that cups-genppd and cups-genppdupdate must be used in order to generate the necessary ppd files and update them into the cups folders.

Well, I can find cups-genppd.5.0 and cups-genppdupdate.5.0 in /usr/sbin but I wonder if these binaries are related to the old drivers (gutenprint 5.0.2) and not to the new ones (gutenprint 5.2.6).

Anyway, I'm a bit messed with this stuff. I've read the man pages but there are very few examples explaining how to upgrade drivers in cups.

Thanks in advance for your help!

Daniel.
