[SOLVED] Printer HP Laserjet 1020 not working after update

rng · 07-08-2017, 03:10 AM

I recently updated from Debian 8 to 9 and it is otherwise working very well. However, the above mentioned printer is not working.

On http://localhost:631, when I try to print a document or print a self-test page, it shows "waiting for printer to become available". Since nothing happens further, I switch off and then on the printer. At this stage, the message becomes 'sending data to printer'. The printer gives out some noise but nothing is printed out. The job is then shown to be 'completed'.

I tried to re-install the printer with command:

Code:

sudo hp-setup -i

but it gives an error:

Code:

error: No device selected/specified or that supports this functionality

I have started restarting the printer, but it has not helped.

Basically, it is not finding printer connected via USB.

There is another observation which may be related: if I start computer with printer on, the mouse cursor appears but it is frozen. It starts moving with the mouse only if I switch off the printer. It keeps working if I restart the printer.

The same printer works perfectly well with another Linux distribution installed on another partition of same computer, hence there is no hardware problem.

Where is the problem and how can this be solved? Thanks for your help.

I've been buying cheapo laser b/w printers for my last 2 printers. I had a 1020 or some model close to that number. I got no good out of it whatsoever under slackware until I installed foo2zjs(?). That clashes with some other printer stuff.

I currently have a hp Laserjet p1102w and got no good of that until I found some linux installer on the cd or website. No trouble now, it operates on the network and anything on wifi prints to it.

This may be the same bug that I found in Crux. Check if you have the usblp module compiled. Cups is supposed to blacklist it but the blacklist doesn't work in the latest version of cups.

You can test by running /usr/lib/cups/backend/usb as root. If you get some message about not being able to uncouple usblp, that's it.

Or, you can try :

Code:

$ lsmod | grep usblp

If it's loaded, try:

Code:

$ modprobe -r usblp

Then, go into /etc/modprobe.d and make a blacklist file for usblp.

I get following output:

Code:

# /usr/lib/cups/backend/usb
DEBUG: Loading USB quirks from "/usr/share/cups/usb".
DEBUG: Loaded 132 quirks.
DEBUG: list_devices
DEBUG: libusb_get_device_list=9
DEBUG2: Printer found with device ID:  Device URI: usb://Unknown/Printer
direct usb://Unknown/Printer "Unknown" "Unknown" "" ""

and:

Code:

$ lsmod | grep usblp
usblp                  20480  0
usbcore               184320  6 usbhid,ehci_hcd,uhci_hcd,usblp,btusb,ehci_pci

I am not sure what they mean.

Have you gone into http://localhost:631 and added your printer?

Normally the usblp module should not interfere with lisbusb communication, but I'm interested in Hazel's comments about a possible regression here. Anyway, try unloading the unneeded module with

Code:

sudo modprobe -r usblp

then (with your printer plugged in) run the hp backend manually like this

Code:

sudo /usr/lib/cups/backend/hp

What (if anything) is reported?

ferrari · 07-11-2017, 05:30 AM

Also, with the printer turned on (but disconnected), open a terminal window and run

Code:

dmesg -w

then connect the USB cable and observe/capture what is reported. (CTRL+C to terminate.)

The printer is not found there also.

I am away from that computer at present. Will try ASAP and give the feedback here.

Hardly surprising it's not found then. Add it.

@business_kid: For a locally connected printer, if the CUPS usb backend (or hp backend for printer supported by HPLIP) can't enumerate the printer URI (ref post #5), then there is a more fundamental problem here. That needs to be sorted first.

When I try to add it, it is not even detected (printer connected through usb) and is not there in detected printers list, so it cannot be added.

Can you please run the commands given in posts #7 and #8. Post back here with the output. A bug report may well be required.

With command 'dmesg -w', on switching on the printer, I get following messages:

Code:

[  431.944033] usb 1-7: new high-speed USB device number 6 using ehci-pci
[  432.112501] usb 1-7: New USB device found, idVendor=03f0, idProduct=2b17

[  454.627744] usbcore: registered new interface driver usblp

Then I performed following commands:

Code:

# modprobe -r usblp
# /usr/lib/cups/backend/hp
direct hp "Unknown" "HP Printer (HPLIP)"

The output as shown above states "unknown".

"hp-setup -i" is still not working. It gives following error:

Code:

error: No device selected/specified or that supports this functionality.

Interesting that the printer model and serial number is correctly enumerated in the kernel output, but both the usb and hp backends are not working as expected. A bug report is required here.
