ML 2010 Issues

Postby DEI11X » Sun Nov 04, 2007 23:51

Hey all,

Im a new fan of Sabayon Linux, but there is one problem I just cant seem to solve... My Samsung ML 2010 printer refuses to print. At first, the driver was not in the driver database, so I emerged the splix drivers by issuing a simple 'emerge splix' command. The drivers appeared, but nothing happened when I tried to print.

Did I incorrectly emerge the drivers? Is there something else I need to do to get this to work?

Btw.. I added the printer via the KDE interface to do so.

Thanks greatly in advance!

See the following Web page for instructions (ignore the bit about Gentoo AMD64, it should work with Gentoo/SL x86 too):

Hey, thanks for the help, but I gave it a shot and still no luck... When I print a test page, absolutely nothing happens.

Any other ideas?

Thanks again,

Mike

Oh, also I noticed that sometimes it says "Printer not connected; will retry in 30 seconds..." in the CUPS admin page... Could there be a problem with cups itself because on some sabayon installs, cups fails to recognize the printer on USB1 at all...

Thanks!

You could update CUPS if you don't already have the latest version, to see if that helps. Also have a look at the Gentoo Printing Guide (see link on above-mentioned Web page) as there may be some pointers in that.

I went through the same headache with my Samsung ML-2510. The problem seems to come from the "USB Autosuspend" feature that was introduced in the 2.6.20 kernel. It's supposed to power down USB devices when not in use, but many devices (especially printers and scanners) don't play nicely and refuse to power on again. Read more about it: https://lists.linux-foundation.org/pipermail/bugme-new/2007-June/016443.html
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/128058
https://bugs.launchpad.net/debian/+source/linux-source-2.6.20/+bug/85488

I'm not sure there has been any progress on this little problem yet. There are supposed to be workarounds that do not involve recompiling the kernel but I never got any of them to work. In fact, I decided to use another linux box of mine as a CUPS print server instead, since it was already running on the 2.6.17 kernel. If you really want to use this printer on an updated kernel, then I believe the best way is to recompile the kernel *without* the USB auto suspend feature. You can find it in the genkernel menuconfig although I am not exactly sure where it is. Look under "peripherals" or "usb" or something along those lines. I do remember that it was marked "EXPERIMENTAL" so it's beyond me why they would enable it by default. Just disable that and recompile and then your printer should start responding when you tell it to print (provided you configured CUPS correctly).

Someone more knowledgeable than me might have a better suggestion. Good luck.

EDIT: OK I might be mistaken. This thread on kerneltrap.org suggests that autosuspend might not be the culprit since they changed the way suspend works in 2.6.23. Here is the thread:
http://kerneltrap.org/mailarchive/linux ... /13/259148

Which kernel are you running anyway? The command "echo $(uname -r)" will tell you. If you are not running 2.6.23, then simply upgrading to it might fix your problem.

Hey all,

Thanks for the help everyone, but I unfortunately had to actually scrap Sabayon last night because I heavily need a fully functional Linux system for this term at school, as we are doing lots of development on linux/unix.

I will give this stuff a read however, and hopefully it can get cleared up soon!

Thanks again,

Mike
