UPDATES AT THE END

printer in question is an hp deskjet 3320v. usb support and usb printer support are both compiled into the kernel (not modules).

dmesg shows:

I get the same problem with my Canon S300... So maybe this isnt just a HP or Canon thing... I can send a text file and the lights blink on my Canon so Iknowe some communication is going one....then nothing...

My only guess is a code page issue? but and HP and a Canon being effected the same way... curious.

I've got what appears to be the same problem on my Epson Stylus Photo 895 (USB). I tried the Gentoo Printing Guide and A n00b's guide to set up printing with CUPS. Turning on the printer creates /dev/usb/lp0. Cups finds the printer name on the USB port, but nothing prints....(I don't get any blinking lights either)

I'm gonna spend some time on it over the weekend, I'll check the CUPS error log to confirm we have the same problem and post the result.....

I have the same problem with a Stylus C70. Modules are loaded, CUPS does see the printer but it simply doesn't print out anything. Tried the steps several times but nothing helped.

Generally it does work. USB reports the printer correctly, and using the Epson printer tools (from the KDE print manager GUI) I can reach the printer, so the connection should basically work.

well what the fsck!

ok ok, what usb controllers are you all using? i've gotta msi via kt333 motherboard using the via tech controllers for both usb 1.1 and 2.0. as i've stated before, it works perfect in windows, so i cant imagine that the hardware is the issue.

another thing to consider... do you guys have usb printing support compiled into the kernel or as modules? i wonder if that has anything to do with it....

if you have a dell notebook, you most likely have the intel 82371ab/eb or the intel82801ba/bam.

if it's a newer notebook, then you probably have the intel 82801ca/cam. but reguardless, if it worked in redhat, then it most likely isn't a controller issue

you can check dmesg to see.

i cant say the same for myself though. the printer didn't work at all in redhat. i had the same exact problem that i do now. although, i didn't do near as much troubleshooting in redhat, so eh.

maybe i'll try compiling the printer support as a module... though i dont see how that'd make much difference. who knows though! it's linux! stranger things have happened....

if you do manage to find a resolution, please please please let me know

My motherboard is a KG7 using a via USB controller (UHCI in kernel). I've haven't got printing or USB support as modules. My USB mouse works fine in Gentoo, and my printer works fine in Windows.

Well, I did a quick little test today and emerged PDQ, and it does print fine!! Caveat: The driver only prints text files, would have to check if there are better ones.

Just wanted to point out that it looks to me like the problem is in gimp-print-cups or cups itself (although cups works in my office environment).

As a consequence, USB doesn't seem to be the culprit in my case.

i've got the latest cups and cups-gimp-print and my epson stylus photo 925 works fine over USB - except when selecting the port it's connected to, I had to change it from /dev/usblp0 to /dev/usb/lp0 - it wasn't autodetected in the KDE setup wizard for some reason.

I did a format and re-install of Gentoo (I learnt lots from the 1st install and wanted to try doing things differently + try reiserfs).

Anyway, I emerged cups, then tried a 'cat test.txt > /dev/usb/lp0 and it worked!!!

I carried on - installed foomatic, ghostscript and gimp-print-cups. I tried a 'cat test.txt > /dev/usb/lp0 and nothing....

I then unmerged back to just having cups installed (the same state it was in when printing worked) and still nothing....

What does everyone think? It seems strange that unmerging the packages doesn't make the printer kick-in....
I'd had a few to drink before this, so the process I took is a bit hazy :roll:

Yes, it really looks as the culprit is somewhere in ghostscript/cups/gimp-print-cups. Probably the driver, I don't know.
I also don't really have a clue how to debug that... If anyone can give pointers then let me know.

I think we can pull out USB issues here as for me it works with PDQ... I should try if it works with LPD... Will let you know.

Actually, I take it back... I don't have the latest cups and gimp-print-cups - I have the latest stable version (i.e. without ~x86 accept flag). I haven't tried upgrading.
