So, I've got a multifunctional printer. It was part of a special discount offer for the laptop I got last December. That's cool and dandy. Problem: it doesn't provide drivers but for that Other Operating System.

I am extremely lazy so I didn't try to find drivers for using it on Debian lenny until just last night a few days ago. Found some references to a japanese website which provides Linux drivers for quite a lot of EPSON hardware (apparently due to some sort of partnership with the original manufacturer): they provide only 32-bit binaries for the printer component's drivers, and not even for the new Debian stable, and building the source code is pretty useless since I cannot figure out their weird post-installation config procedures, which is part of the auto-installing 32-bit binaries, but isn't documented or (apparently) provided in the source code distro.

Hit the nail with a spanish forum post. I had to install a newer version of the Gutenprint driver (lenny provides 5.0, the post stated 5.2.3 as minimum requirement, which also happens to be the latest provided at SF.net). A simple backport from the unstable (Sid) distribution was sufficient.

# apt-get -b source cups-driver-gutenprint

The first hard part was chasing down the generated .debs mixed between the ones from my other simple backport from sid (GIMP 2.6). Okay, not so bad. But then I figured out that the new drivers I was expecting wouldn't appear in foomatic-gui or KDE's printer manager tool (kcmshell printers, although you may know it better for its entry in the Control Center). Uncanny.

Then I figured it would appear in the CUPS config itself.

Next step: scanning with SANE!
