need help with installing new printer

[teabutterfly2047]

Hello fellow Ubunters,

I'm using xubuntu. Here are the specifics:

utilisateur@utilisateur-TravelMate-P253:~$ hostnamectl
   Static hostname: utilisateur-TravelMate-P253
         Icon name: computer-laptop
           Chassis: laptop
        Machine ID: 46037e7c1388fbb5aa7bdbe0525587dd
           Boot ID: 4a76e79c9e2449f381a11cf5b717078c
  Operating System: Ubuntu 18.04.5 LTS
            Kernel: Linux 4.15.0-122-generic
      Architecture: x86-64

Anyways, I just bought a brand new printer, it is an HP 6000 series Envy all in one printer/scanner.

The printer is turned ON and connected to the laptop by a type B USB cable.

I followed the manufacturer's instructions and dowloaded the HPLIP software for linux (the tar.gz package). I upgraded the HPLIP to the latest version using the Synaptic software. I used the visually graphic version of Synaptic, though I suspect a sudo synaptic command in a terminal might be more effective. Anyways, I followed the step by step instructions of the help section of Synaptic and I suspect there was a problem with the HPLIP upgrade and would love to get help troubleshooting the situation through commandsz typed in a terminal.

After the HPLIP software upgrade and the installation of the printer, I tried to print a test page but got an error message. No test page was printed. I tried to scan a page, and my simpleScan software doesn't recongize my new printer for some reason (there's a missing link soemwhere, I suspect).

Lastly, in a terminal, I tried the lprm and the lpq commands and the name of my former printer appeared, instead of the new one.

lprm

lpq

so here am I stuck with this new printer. Thank you kindly for your help.

I checked and rechecked, can't find what's wrong. This is driving me nuts. Please HELP.

https://docs.xubuntu.org/1804/user/C...-scanning.html does that not work?

[ajgreeny]

Just out of interest, what output do you get in terminal when running command driverless list?

[teabutterfly2047]

Thanks for replying.

No, I've been on this webpage before and followed the step by step instructions. It still does NOT work.

I must say my system is in French and those instructions are in English. At some point, it is instructed to do the following:

Select your printer and click Forward

the thing is there is no French equivalent to "forward" in French ythat I could identify. This may be the missing link. Talk about being lost in translation!

I'll come back here with screenshots from my desktop, maybe it will be clearer.

ippfind was the most useful, but only when avahi was running. I had to enable avahi, wait 30sec, then run ippfind to get a list of printers and scanners. Generally, I disable and mask avahi.

great stuff ajgreny! Taught me something new.
I'd been using system-config-printer - which is probably the GUI app in most flavors.

[teabutterfly2047]

@TheFu never heard of avahi, don't know if I have it in my system.
How do i enable/disable avahi? Thanks

Please don't use images for text. You can copy/paste the text alone. 500B vs 20KB - same information.

The page where you ran sudo didn't have correct commands. Details matter.

Why was "driverless list!" used? That was not the command requested.

Here's what I get from the correct command:

$ driverless list
DEBUG: Started ippfind (PID 417966)
DEBUG: Started post-processing (PID 417967)
ippfind: Unable to use Bonjour: Daemon not running
DEBUG: PID 417967 (Post-processing) exited with no errors.
DEBUG: PID 417966 (ippfind) stopped with status 2!

and with ippfind:

$ ippfind 
ippfind: Unable to use Bonjour: Daemon not running

Bonjour is the Apple name of the service similar to ZeroConf. Apple has been running the "CUPS" project for years. On Linux, the ZeroConf protocol is implemented by avahi. I think all desktop versions of Ubuntu install and enable it by default.

If I enable avahi, then run those commands again ...

$ driverless list
DEBUG: Started ippfind (PID 12065)
DEBUG: Started post-processing (PID 12066)
DEBUG: PID 12065 (ippfind) stopped with status 1!
DEBUG: PID 12066 (Post-processing) exited with no errors.

$ ippfind 
ipp://romulus.local:631/printers/BRFAX
ipp://romulus.local:631/printers/MFC240C
ipp://romulus.local:631/printers/Samsung_ML-1740
ipp://romulus.local:631/classes/laser
ipp://romulus.local:631/printers/scx4100

Romulus is my print server on the network. It has a Samsung laser printer and a Brother MVC all-in-one device connected. The romulus.local is proof that avahi is being used. {hostname}.local is how avahi makes accessing local systems possible for people who don't run an internal DNS or modify all the /etc/hosts files on all their systems. That's a name resolution thing.

@TheFu

thanks for the detailed answer.

Please don't use images for text. You can copy/paste the text alone. 500B vs 20KB - same information.

OK. I must say I tried to copy/paste the text from the terminal and it didn't work (OK, I solved that, now I can copy/paste from terminal, it's no longer an issue). Plus, having Asperger's and tired eyes, I am more visually oriented. It's time for me to magnify the text here in this forum, because the font size by default is too small for me to read and then I misread the command suggested by @ajgreeny.

Of course, details matter. Please bear with me I'm burnt out and exhausted. Anyways, now that I'm fully rested and caffeinated, here is what I get :

DEBUG: Started ippfind (PID 5141)
DEBUG: Started post-processing (PID 5142)
DEBUG: PID 5141 (ippfind) stopped with status 1!
DEBUG: PID 5142 (Post-processing) exited with no errors.

I guess I have avahi enabled by default. I didn't enable it on purpose, as I don't even know how to do that! do I enable/disable avahi through the Synaptic software?

here's what I get with ippfind

utilisateur@utilisateur-TravelMate-P253:~$ ippfind
utilisateur@utilisateur-TravelMate-P253:~$

So enabling avahi seems to be the key here. I've never used avahi before, never had to. How do I enable/disable it?

any suggestions welcome.

PS: I edited all my previous posts and deleted unnecessary images.

hello there,

it's me again.

I just used

system-config-printer

as suggested and went to the help/debug section and followed instructions. I was told to type the following in a terminal:

su -c 'journalctl -u cups.service --since="None" --until="2021-09-30 09:17:15"' > troubleshoot-logs.txt

then I was asked to authenticate, I entered my password and the authentication was denied as follows:

utilisateur@utilisateur-TravelMate-P253:~$ su -c 'journalctl -u cups.service --since="None" --until="2021-09-30 09:17:15"' > troubleshoot-logs.txt
Mot de passe :
su : Échec d'authentification
utilisateur@utilisateur-TravelMate-P253:~$ su -c 'journalctl -u cups.service --since="None" --until="2021-09-30 09:17:15"' > troubleshoot-logs.txt
Mot de passe :
su : Échec d'authentification
utilisateur@utilisateur-TravelMate-P253:~$

let me translate here: "Mot de passe" means "password" in French
"Échec d'authentification" means "authentification/login failed"
could it possibly be that I don't have administrator rights on my own computer? My laptop was first set up by an ex-boyfriend... It is possible that he has an admin password different from my user/login password.

When I use, for example, this command:

sudo synaptic

and I am asked to anthenticate, I enter my password and it works.

So now I'm doubtful: are there two different passwords? Do I have only user rights, and no admin rights?

I went through the whole help/debug process and ended with a message saying "sorry! there is no answer/solution to your problem, you may report a bug".

Any input/advice welcome here.

What output do you see from command groups

[teabutterfly2047]

@ajgreeny

command groups:

utilisateur@utilisateur-TravelMate-P253:~$ groups
utilisateur adm cdrom sudo audio dip video plugdev fuse lpadmin netdev scanner sambashare divers
utilisateur@utilisateur-TravelMate-P253:~$

utilisateur = user
divers = miscellanea
