Question
I have a Kyocera FS-820 (BW Laser Printer) that worked for a long time on my Linux distro. I bought a new computer, re-installed my distro, and now, I have problems with my printer. On three different Linux install (two Gentoo, one archLinux). My goal is to install it on my Gentoo server.

The problem I have is that Cups "lost" the connection to my USB printer after a short time. If I power down and then power up my pinter, Cups will see it, and I will be able to print, and the result is perfect. But if I wait like 30sec or 1min, and I try to print again, Cups will tell me "printer not connected; will retry in 30 seconds".

If I do: "lpinfo -v"

The result after I started the printer:
------------------------------------------------
network socket
network beh
network http
network ipp
direct usb://Kyocera/FS-820
network lpd
direct parallel:/dev/lp0
direct scsi
serial serial:/dev/ttyS0?baud=115200
------------------------------------------------

After about 30sec:
------------------------------------------------
network socket
network beh
network http
network ipp
network lpd
direct parallel:/dev/lp0
direct scsi
serial serial:/dev/ttyS0?baud=115200
------------------------------------------------

As you can see, the USB printer is not there anymore. The "usblp" module is compiled directly in my kernel (not as a module).

It was working in the past, and I've even installed a Windoz to validate that it's not my printer, and it work great in Windoz.

For the USB system it is not off-line, that definitely makes it a cups issue.

It might be that the usb code does a check wrong, as "printing" to the file
/dev/usb/lp0 works.

Can you try to use the url: "file:/dev/usb/lp0"
it might help. The problem then is that is there are more printers
the order might change, and that shouldn't be the case with usb:/...

If the Kyocera can handle HP compatibility, you could try the hplip package.
(that's an intermediate between cups and hp printers).
