USB Printer not detected / displayed in web UI (HP PSC 1510)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Plug in printer, turn on printer
2. Reboot snake NAS, login, Look inder Printers-> Sharing

What is the expected output? What do you see instead?

Nothing listed under Sharing-> Printers

What version of the product are you using? On what operating system?

Kernel version: 2.6.16-gazineu
NAS version:    SNAKE OS V1.3.2 (20111019) (from original)

Please provide any additional information below.

My printer is an all in one jobbie (has built in scanner), HP PSC 1510

I'm running SuSe linux and have configured the samba printer shares on the nas 
and they are displayed on the network, I have installed the correct CUPS HP 
drivers and looking at the CUPS log I can see errors, but I think thise are 
just related to the fact that the NAS dosn't detect the USB printer, the CUPS 
log moans that the printer is idle and goes on about some font. I have ssh 
access to the NAS box, so any pointers on where to start would be great, can I 
load any kernal modules with snake or does they have to be compiled from 
source? 

Thanks in advance

It's a bit suspicous that there's no mention of the printer in the log. Can you 
try to uninstall USB/IP and reboot?

Ok so after removal of the usb/ip the output is as follows, Does snakeOS have 
cups backend installed? I have looked through the source and can't see it. HP 
have there own opensource drivers that integrate with cups and ghostscript, the 
kernel driver usblp is blacklisted / replaced by the hp drivers. I can see in 
the snakeOS syslog that the printer is noticed and usbcore loads the usblp 
driver for it,

Sep 7 02:58:48 boot-kernel: drivers/usb/class/usblp.c: v0.13: USB Printer 
Device Class driver

I'm looking at building a  hp & cups opkg but looking at the debian 
repositories theres quite a few dependencies, and as i'm on an rpm based system 
It's not like i can get packagemanager to download them all into a nice little 
directory where i could work on them. There must be an easier way to add hplip 
and hpcups support? can they be added to the kernel when built? I have built my 
own kernel once but not had much experience with embedded devices / arm 
processors.

Its a shame because I specifically bought this Star NAS device to share that 
printer, I asked about it specifically when I bought it, and they assured me it 
would work. The original firmware never did work with the printer I couldn't be 
bothered to return it and so its been in a draw for 2 years. SnakeOs rocks tho, 
thanks to everyone thats contributed. 

Strange..

# modprobe usblp
modprobe: module usblp not found in modules.dep

# rmmod usblp
rmmod: can't unload 'usblp': kernel does not support requested operation

I never used the printer sharing feature, so I'm not sure if I can much help. 
For printing support snake uses p910nd. http://p910nd.sourceforge.net

Does the printer require that the HP driver to work at all? I could try to 
compile it for snake but can't promise anything.

Usblp is compiled into the kernel so there's no module to modprobe. Module 
unloading is disabled, I guess it's just that nobody really needed that yet.

These are driver initilization messages. You also get these with no printer 
attached. What would be interesting to know is if there's anything in the dmesg 
output if you plug the printer in at runtime.

I'm such an idiot, the usb was pulled out the back of the printer when I 
plugged it into the NAS, I'm sorry for wasting your time!!

I can now print from windows! with clients that have the HP drivers installed, 
However from my linux box I'm having trouble, I've got the HP drivers installed 
and when I send print jobs they appear on the NAS but the printer does nothing, 
I'm a little confused as I've set a samba share name as "printers" which is 
actually "/usb/USB38GB/printers" and from FTP the directory where the print 
jobs appear is "ftp://snake/USB38GB/printers" but nothing happens.
