Printing in US Letter size instead of A4 - Printer error

[EnDorTales]

When I print, I always get the printer output set back to "Letter" size. Correct size would be A4. Then the print job stops with an error code, and I need to unlock the printer manually by erasing the print job.

Setup:

Ghostscript Version 10.03.0-3 installed through Snap on a Raspberry Pi4B/4GB, running RaspianOS Bookworm. All updated.
CUPS 2.4.2 installed on the Raspi.
Dell 1355cnw printer as network printer installed

Printer settings in CUPS:
Beschreibung: Dell_MuFu
Ort: HomeOffice
Treiber: Dell 1355 Foomatic/foo2hbpl2 (recommended), driverless, cups-filters 1.28.17 (farbig, 2-seitiges Drucken)
Verbindung: implicitclass://Dell_MuFu/
Standardeinstellungen: job-sheets=none, none media=iso_a4_210x297mm sides=one-sided

Printer settings in Ghostscript:

Printer Tray settings:
MPF Paper Type | Plain
MPF Paper Size | A4 (210 x 297 mm)
MPF Custom Size - Y | 297 millimeters
MPF Custom Size - X | 210 millimeters
Display Popup | On

This are the start settings. Whenever I print (paper size set to A4 in the print dialogue of the app), the printer claims it has "Letter" instead of A4 paper format.

Furthermore the Tray settings of the printer are set back to "Letter". The printer is not touched by anything, beside the print job being send to the printer.

This happens no matter if printing through AirPrint from an iPhone, or by Ethernet from a Mac (both on the current OS versions). But it already happens when I send a test page from the Ghostscript web server site.

In addition the margins of the page are set to zero: It starts printing right on top of the page, and has no left margin.

I have no idea why the settings are changed to US Letter size by itself - I am located in Germany and never use US letter.

Hello,
I feel less alone :) I have exactly the same problem but with a completely different PC and printer...
When I print, I always get the printer output set back to "Letter" size. Correct size would be A4. Then the print job stops with an error code (024-298 for me with the xerox), and I need to unlock the printer manually by erasing the print job.

Setup:
Ghostscript Version 10.03.0-3 installed through Snap on a Sony-Vaio VPC-YB3V1E, running Debian 12.5 Bookworm. All updated
CUPS 2.4.9 installed on the Debian.

As EnDorTales :
Whenever I print (paper size set to A4 in the print dialogue of the app), the printer claims it has "Letter" instead of A4 paper format.
Furthermore the Tray settings of the printer are set back to "Letter". The printer is not touched by anything, beside the print job being send to the printer.
In addition the margins of the page are set to zero: It starts printing right on top of the page, and has no left margin.
I have no idea why the settings are changed to US Letter size by itself - I am located in France and never use US letter.
Below is the printed test page and the printer error code...

In addition
After searching in the files installed by snap, I was interested in the wrapper file corresponding to the driver I am using: /snap/ghostscript-printer-app/815 (or current)/usr/bin/foo2hbpl2-wrapper
In this file, all "default" media is set to "Letter".

I tried to modify this file to test but impossible to overwrite it because the snap folder is read-only...
I feel like it's somewhere around there... but this is getting too technical, I'm not a developer and I don't know what to do precisely... :/
Also note that the values ​​indicated in the media sizes menu have little to do with what I see in the "Tray" menu of my printer... Perhaps a correction should also be made on this point...

The right column numbers match what I found in the file "foomatic-db/opt/foo2hbpl2-PageSize.xml" that I looked at in the foo2zjs driver source code that I found here https ://github.com/mikerr/foo2zjs_

Thanks

I've stumbled about the exact same thing, did you ever find a solution or a work around? Except from buying another printer?

[Arkanoid1973]

Hi, Unfortunately no, I haven't found a workaround and haven't switched to Linux for this reason, being reluctant to buy a new printer just for a driver issue.... Le mer. 8 janv. 2025 à 08:51, Ravira43 ***@***.***> a écrit :

Actually I didn’t follow up on this. I dropped the printer, but for a mechanical malfunction, not for this annoying issue.

What @Arkanoid1973 found sounds interesting. Usually you can modify file permissions to make them editable. Maybe you need to assume „root“ authority to allow for it.

I found a solution for this problem, at least it's working for me.

I have the ghostscript-printer-app from the snap store up and running on my pc and also did setup the printer through the printer settings of my OS (opensuse).

The printer was found automatically by the setup wizard (because of the ghostscript-printer-app).

Prints of a few test pages were immediately successful

Hello,
For my part, using the “ghostscript-printer-app” application from the Snap Store always presented the same problem with my OS (Debian 12), namely that the print job was correctly sent to the printer but resulted in error 024-958 on it.
I completely uninstalled “ghostscript-printer-app” and simply installed “printer-driver-foo2zjs” (sudo apt install printer-driver-foo2zjs).
Then I added the printer in CUPS (v2.4.2-3+deb12u8), it was recognized without issue and the printing succeeded.
I don’t know what I missed during my attempts in 2024, but the fact remains that today it works.
