[cups.general] The Famous "Media tray empty!" error - revisited

[Vincenzo Romano]

Hi there all.

I've just hit my head on this problem. It seems to me it's due to
a problem with the backend. As far as I've seens on the web, only
*USB* printers run in the problem.
Now, I've been using my Samsung ML1710P (USB+Parallel) for a while with
no  problem at all. And suddenly it stopped working.
What has appened in my system is that I've done an upgrade of the compiler *and* an upgrade of the kernel.
I'm running:
- Gentoo 2004.1
- CUPS 1.1.20
- gcc 3.3.3 (Gentoo Hardened Linux 3.3.3-r6, ssp-3.3.2-2, pie-8.7.6)
- Kernel 2.6.6 or 2.6.6-mm5

I've seens somewhere a posting from a guy switching from USB to Parallel and solving the problem so, what I can argue is that:
1. either the USB backend gor hurted by the compiler
2. or the Linux USB-Printer support got hurted by some "code fix" or by the new gcc
3. or a mix of these two.

At the moment I have no parallel cable to test, but am pretty sure that this is the way to solve the problem. Maybe.

Regards.
