installation errors

[przerzym]

It may be that I'm doing something wrong here, but I've tried to find an answer myself to no avail.
I'm on Ubuntu 24.04.1, my printer is HP LaserJet 1020 (USB-connected) and it works fine. When I run the manual duplex script, after choosing the printer and confirming I get this:

found printer: HP-LaserJet-1020

Duplexer installed.

And so, of course, despite what it says at the end, it doesn't get installed. Is that a bug or some misconfiguration on my part?

[dentys03]

Duplexer installed. - solved this by updating the "Installation finished." message.

The other errors seem to appear because you didn't run the script in an expected manner: download, extract, move to the install.sh folder, run the script from there as root.

I'll update the instructions.

Thanks for reporting. Please test again and come back to let me know how it went.
Enjoy!

Thank you for a quick response! I'd realised what I did wrong and now I'm embarrassed for wasting your time.
I downloaded the installation script only. I don't know what I was thinking.
So yeah, the installation has gone through now, BUT the program doesn't work. I click print, the system window pops up, I choose the virtual duplex printer, there's a very quick loading screen (not every time though, so I assume it only appears for bigger files) and then nothing. The printer doesn't register a job. It doesn't appear in cups either. Has that happened to people before?

[dentys03]

Check the log file /var/log/cups/error_log maybe you find hints in there.
Else, post that log here.

[przerzym]

I'm moving forward, but not there yet. The program started working when I removed the printer and added it again, but through HPLIP this time. However, it only prints odd pages and finishes without displaying the window that allows printing the even ones.
I know that the issue has been discussed before, so I checked different things indicated in that thread.

The log:

I also get this message in the log:

And then it repeats for several languages. Don't know what I could do about this one, I have both hplip and cups updated to the newest version.

When I try to run the part of the code that should show the window...

sudo --user=$user \
	zenity --question --title="$title" \
        --text="<big><b>Flip and reinsert the entire paper stack when printing has finished,\n\n then press Procceed.</b></big>\n\n\n\n

...I get this:

PS
I've stranded quite far from my initial question, should I just paste this comment into the 'Proceed window' thread instead of continuing here?

[dentys03]

something's wrong here :

Fri Oct 4 01:24:59 PM CEST 2024 --- Running on display number :0
This option is not available. Please see --help for all possible usages.
Fri Oct 4 01:24:59 PM CEST 2024 --- User interface has been shown.
Fri Oct 4 01:24:59 PM CEST 2024 --- User aborted print job

the bolded entries point to a failure from zenity.

I don't understand what "--d" option it's complaining about. Either your zenity has a bug or command line gets confused with the parameters

This doesn't look like a bug for now. Looks like installation support, compatibility issues with zenity... What version is your zenity ?

[dentys03]

i'll close this for inactivity.
reopen it if it's still actual.

thanks.

[przerzym]

Sorry for disappearing for so long, I know it's not good etiquette. I don't have permission to reopen the thread. I checked, my zenity version is 4.0.1

[mpeter50]

I have the same issue. The virtual printer gets paused as soon as it gets a print job.
In the system log I see the zenity command you try to run, and by running it manually I also get the "This option is not available" in the terminal.

I have Zenity 4.0.0, on openSUSE Leap 15.6.
According to zenity --help and man zenity, this version of Zenity does not support the --display parameter. If I run the command without it, the dialog pops up and I can interact with it, so its likely this is the issue.

I see that the latest version is 4.1.90: https://gitlab.gnome.org/GNOME/zenity/-/tags
If I search for the --display option in all project files, I get no results. They dont have a changelog, but I also havent found anything related to it in commit messages.

[mpeter50]

I have edited /usr/lib/cups/backend/duplex-print and commented out --display="$DISPLAY" \ on line 80 and 134.
After that I resumed the printer, and now the zenity dialog shows up as expected, both at the beginning and when it say to flip the page. It does not conitnue printing when I press proceed, but thats for a different issue.
EDIT: the shell got confused at one place about the commented line, so I rather deleted all 3 --display lines, and now it does print

Do we need that option anymore?

Also, where did you read about this option?

[dentys03]

Hello.

Thanks for the awesome debugging.
For another week, I won't be at the computer to test - I'm assuming I found the "display" option in the manual of my zenity version. I'm running on debian 10 currently. Can't remember which zenity version I have.

This could be solved easily by checking everytime which zenity version is installed in the system.

I'll update the code as soon as I have the chance to test everything.

Thanks.

[p-rotom]

Any update on this? I might have the same problem as mpeter50 here as I also don't get any window to open and the print job gets paused immediately. I'm on Ubuntu 24.04.
