[SOLVED] Printer issue - HP-1020

Alok Rai · 11-30-2020, 07:57 AM

I've had problems with getting my HP 1020 printer to communicate with my computers in the past. So, I went back to my earlier posts, and retrieved the instructions there.

I installed my printer, with the foomatic driver, etc, following the excellent routine suggested by Mark Campbell on https://mark911.wordpress.com/2014/1.../#comment-1378

However, my printer still reports its Printer State thus : Stopped - Backend /usr/lib/cups/backend/usb does not exist!

But lsusb recognizes that there is an HP-1020 printer attached.

Bewildered, I seek help!

Further, the "Print Test Page" command on the CUPS page is greyed out.

Most likely you have the old CUPS assignment. This is how it show look now:

Code:

cups.path                          enabled disabled    
cups.service                       enabled disabled
cups.socket                        enabled disabled

Code:

systemctl list-unit-files | grep cups

What it actually likes at the moment is this:

$ systemctl list-unit-files | grep cups
cups.path enabled
cups-browsed.service enabled
cups.service enabled
cups.socket enabled

So what do I do now?

Is folder "/usr/lib/cups/backend" empty ? Is file "usb" in there?

Alok Rai · 11-30-2020, 08:59 PM

Folder "/usr/lib/cups/backend" is NOT empty. In fact, there is a "usb" file lurking in there!

So what do I do now? Thanks for your help.

See if this solution works:
"copy /usr/lib/cups/backend-available/usb to /usr/lib/cups/backend/"

Alok Rai · 11-30-2020, 10:27 PM

See output below - that was summary!
Meanwhile, there is a "usb" file in both backend and backend-available.

$ copy /usr/lib/cups/backend-available/usb to /usr/lib/cups/backend/

Command 'copy' not found, did you mean:

command 'ropy' from deb libdisorder-tools
command 'bcopy' from deb bacula-sd
command 'mcopy' from deb mtools
command 'copyq' from deb copyq
command 'hcopy' from deb hfsutils
command 'fcopy' from deb fai-client
command 'rcopy' from deb rdmacm-utils

Try: sudo apt install <deb name>

Alok Rai · 11-30-2020, 10:29 PM

I retried the same command with "cp" instead of copy, and got a response that the two files - in backend and backend-available were the same.

Now?

verndog · 11-30-2020, 10:37 PM

Use "sudo cp ..." instead.
If that doesn't work try re-installing CUPS.

Alok Rai · 11-30-2020, 11:31 PM

~$ sudo cp /usr/lib/cups/backend-available/usb /usr/lib/cups/backend/
[sudo] password for alok:
cp: '/usr/lib/cups/backend-available/usb' and '/usr/lib/cups/backend/usb' are the same file

So that didn't get me very far, alas!

Now, how would I go about re-installing CUPS?

verndog · 12-01-2020, 06:37 PM

Code:

sudo apt --reinstall install program

Alok Rai · 12-01-2020, 09:39 PM

Please forgive my ignorance,verndog - but would that be a single command to reinstall and install?

So, code: sudo apt --reinstall install cups

Alok Rai · 12-01-2020, 11:27 PM

Done. But I'm afraid the situation seems unchanged - so, the systemctl command still reports the same state:

$ systemctl list-unit-files | grep cups
cups.path enabled
cups-browsed.service enabled
cups.service enabled
cups.socket enabled
