Testing required for USB printers

[Oleg]

Guys, I've recompiled printer.o module which is used in the firmware in order to fix the kernel oopses. But I need a feedback from the users who is experiencing problems with printing with 1.7.5.6-2 firmware and a facing to kernel oops in the logs. Also I need a feedback from other users to whom current firmware works ok.

So, please download the new driver module usingthis link.
Once you've downloaded it please disconnect your usb printer from the router, power it off then on and copy printer.o to /tmp directory on the router (scp printer.o admin@my.router:/tmp)
Once you've copied the file please establish the ssh/telnet session to the router and do the following

rmmod printer

After that execute

insmod /tmp/printer.o

Now you can connect your printer back to the router.

After that please execute

cat /proc/usblp/usblpid

and post the results here. Also try printing anything to see if that works for you.

P.S. You could also copy printer.o to the usb flash driver and execute

insmod /mnt/usbfs/printer.o

instead to load new driver.

To whom who has problem with printing: guys, if you want to fix the printing problem please perform the testing mentioned. Otherwise the problem will be never fixed - I need a feedback.

# cat /proc/usblp/usblpid
Manufacturer=Lexmark
Model=Lexmark Z22-Z32
Class=Printer
Description=Lexmark Z22-Z32

The printer is correctly recognized in the status window, but printing in any way (lpr/raw) does not work. With the old printer module the results have been the same.

Just to clarify: I'm trying to track the problem with kernel oopses in the system log. Is there anything strange in the log?
Also, some users reported that ASUS original firmwares are working ok in the printing part, but does not work with custom one. Have you ever tried printing with ASUS firmwares?

[narcis]

As far as I know the system log doesn't show anything suspicious when trying to print and the situation was the same with the original Firmware, but it might be that there have been more error messages in the system log with the original firmware. I'd try that out, but I think it would be better if I printed from the router itself via a ssh/telnet connection, so I can make sure that the networking part doesn't make any trouble. Can I pipe some file through to the LPR, and if so, how?

Please I'm a newbie to this..if you explain how to copy it to TMP and how to conect with a telnet session..I want to try...my HP840C is now not working (it did for one testform..after that..no connection anymore)

[Dusty]

I want to test this, but how can i copy/move the file:
printer.o to the /tpm directory on the router?

[ebakke]

Want to test as well, doesn't look like ssh is running, with my limited Unix knowledge, is required by scp.
Can not use the card slot on the printer as well using ftp, as the new firmware is not accepting these, so stuck to get the printer.o file on the router.

Any suggestions?

[Oleg]

Ok, I see. Wait for the new test firmware.

try this one

ít SHOULD open up a ftp server upon your wl500gs root

never tested this anymore was tested with 1.6.5.3 for the last time..

[Oleg]

Guys, try using this firmware. It contains "right" usb printer module. Also it has vi editor compiled in to the busybox.

[Pandabeer]

Oleg!! Perfect....it's working with my HP Deskjet 840C!!

Great Job...

[Josephus]

still not working...
i got the same dmesg

hub.c: new USB device 00:04.0-1, assigned address 2
printer.c: usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid 0x04F9 pid 0x011E

Oops in fault.c::do_page_fault, line 192:

and some stackdump

Its a laser printer, but afaik with this new printing daemon i should handle any printer, right?

[Oleg]

Yes, it should...

[ALAIN]

i did a test with my printer :

HP 930C, USB port (9101, mode raw) : working fine

The firmware is 1-7-5-6 release 2 ( my router is a WL500b and i used the recovery mode to ulpload this firmware).
I use a "noname" USB hub between the router and the printer.
I have also conneected on this hub :
- a philips webcam PCVC675K : working
- a USB2 HDD (case "connectland", 2.5") : working

I also now have voice, video, file transfer and webcam with MSN Messenger (with the previous firmwares, i had only the webcam!).

Congratulations for your job Oleg.
