Trouble getting new HP 7740 Printer working

SaintDanBert · 04-01-2024, 07:17 PM

Colleagues,
Q1. Can someone help me get my new printer working?

I unpacked and powered the new printer and connected it to my home-office LAN. My workstation ping'd the printer just fine.

I logged into my worktation and launched HPLIP Toolbox lke I have done time and again. Using HPLIP, I removed the printer that had failed, then performed a system restart "reboot".

After restart, again, I used HPLIP to add the new printer. This process worked as it had done for years. I opened a shell and restarted CUPS. I was able to print a test page and a few documents as "acceptance test." This is when the troubles started.

I have noticed that HPLIP has a current version 3.23.12 while my repositories hold version 3.21.12. I don't find any "release notes" details that address the issues I'm having.

My Linux Mint and all of component parts are up to date using the included update-manager utility.

I'm primarily interested in printed documents created with LibreOffice. I'm running version 7.3.7.2 — with CUPS version 2.4.1op1-1ubuntu4.8.

I know that there are a lot of "moving parts" involved in having information appear on a printed page. It seems that every app-suite has its own printing dialog. Yes, they eventually reach out a "system printing dialog" but discovering what is going on is serious software archeology.

I got notifications saying, "... printer offline or unplugged ...", "... printer error ..." and similar. Jobs would enter the printer queue and go "pending" or "held." When I tried to shutdown the printer, it would display "shutting down" then spin its busy circle, ...
... eventually, I pulled the power plug.

On the workstation, I flushed the queues manipulated the "printer settings" and tried to use the printer again without success.

I also tried removing the printer with HPLIP, restarting the workstation, and repeating everything I thought would work ... without success.

SADLY -- The printer installed and works fine from Windows-11 with "HP-Smart."

The parts I'm using:

The printer and workstation are wifi LAN connected usin ASUS AI-Mesh,
Linux Mint 21.3 with Cinnamon Desktop
HPLIP version 3.21.12
HPLIP Device Manager v15.0(QT4)
HP OfficeJet 7740 Wide Format All-in-One, model=SNPRC-1500-02
HP Serial Number CN376BHHM8

I've used HP printers with HPLIP and Linux Minx for quite some time. I use the Cinnamon Desktop as well. When my printer died, I replaced an HP 8600 printer with an HP 7740. I'm having no end of troubles... so much so that I struggle to find the words to describe what is going on.

Thank you in advance,

The printer is supported by HPLIP version 3.16.10 but it is also supported by IPP everywhere. So theoretically it should be automatically detected and configured without doing anything. cups-browsed as well as avahi should be running. I have not played with 21.3 but IPP everywhere seemed to work with 20.3.

With my HP 4001 in a similar fashion once it was installed via Windows it was automatically detected with debian 12.

Another method of debugging this issue is to plug the printer in question into a port on your router and from there configure it as you would a server with an static ip address in your routers static lease pool.

If understand, you suggest direct-wire to the LAN instead of using wifi-connection.
Am I correct with this? I'm not clear about what to look for to diagnose wire success vs. wifi fault?

Is there any way to get good details about what is happening when the print request fails during a wifi connection, but a similar request works fine with a USB connection? Which logs etc should interest me?
NOTE --- While the printing components are complaining that the printer is not connected, the printer IP responds to [b]ping[/] and I can use a browser to connect to the printer, built-in web page.

Baffled,

What does the output of the command show for your HP?
sudo lpinfo -v

On debian 12 my HP is automatically detected as:

Follow-Up
After a factory reset, I configured the printer's wifi. Then used the HP Smart utility from my wife's Windows-11 workstation to add the 7740. From Win-11 everything about the printer works as expected.
Returning to my Linux Mint workstation, I continue to have the "not found, not connected" issue from wifi. I have this trouble using both the {system settings}=> {printers} => {add printer} as well as using HPLIP v3.21.12. (The latest edition of HPLIP is v3.23.12 from their website)
I feel reasonable to suspect that there is a "driver" issue for wifi conx'd printer vs. Linux Mint v21.3. The new edition of HPLIP will not build on Mint 21.3 due to dependent package issues.

I do not have this issue with a USB connection from the workstation to the printer.

Thank You In Advance,
