P: Print module list of page sizes doesn't update

Same issue here, can't load borderless papers, and creating a custom one w/o borders doesn't work either. Printing from PS does work fine

Sonoma 14.4.1, LRC 13.2, Canon G620, Airplay driver.

this problem also exists in Adobe Reader.  looks like Adobe and Apple not playing nice again.

Just curious, has anyone installed today’s macOS 14.4.1 update, and does it help with this problem?

I am using MacOS 14.4. with Lightroom Classic 13.2 and am having problems printing from the Print module in Lightroom. Until some time ago I had no problems. In Lightroom, I am shown completely different paper formats (less and some fancy formats) than when I open the print dialog via another application (see example images). Above all, communication with the printer in Lightroom then works very poorly and printing often fails.
What could be the reason for this? Is this a Lightroom problem?
I am using an Epson ET-18100 with the latest firmware.

In Page Setup in LR Classic, I see the following options for paper sizes:

These look like European sizes. There's no 4x6, 5x7, etc., and no borderless options.

In Photoshop 2024, I see the correct list of options:

This is the list I'm familiar with. I can print 5x7 bordlerless with my Canon PRO-300. 

Any idea what's happening? 

Quoting another user @michele98A1 - and I have verified this with Epson P800 printer and a number of applications including PS, Preview, MS365, MacOS Photos as well:

"In Lightroom Classic's Print Module, the Page Setup pop-up menu that lets me select a paper page size no longer changes when I switch printers. This used to work (I have been printing in LR for years) and I can still print to the printers. I just can't tell LR the page size I want.

I have no issues in other apps (PS, QImage, etc) which correctly show me the list of supported pages sizes. Indeed, LR seems to know about the options as the "Printer..." dialog has a Scale to fit paper size option that is correct. It just looks like the Page Setup list of print sizes never gets updated and stays on the "Any Printer" default list.

I'm on a recent Macbook Pro M3 running current Sonoma (14.4) , latest version of LR (I tried deleting, re-installing, installing prio version, rebooting laptop, updated print driver, and anything else I could think of to no avail). Main printer I use is a Canon Pro 100, but same issue on another printer. And as I say, PS (etc) has no issues."

Problem is specific to LrC (tested on latest 13.x version) and apparently Capture One, but other applications including PS are working as designed.

Workarounds:

1.  create new custom sizes. Needless to say, this is a PITA but it is doable. Sometimes you need to do this for special sizes - like I use 17x25 paper which isn't a known size when this works.
2.  Export the photo to Photoshop (with Lightroom Edits), and print from there. No need to do anything to the image at that point other than print. All the paper sizes including borderless and rolls should be present and honestly the PS print configuration is less confusing and soft proofing is in the print dialog which is helpful. Plus no 4 different Print... buttons like LrC! I did a borderless using this approach. There was a tiny difference in size which, with borderless, resulted in a sliver of paper that didn't get printed. I don't normally print borderless and that's been problematic with rolls in LrC in any case.

I have the same issue with the latest Sonoma update. What can I do????

Most page sizes are missing, including borderless:

Possible background info…AppleInsider is reporting that users of other printers are noting issues caused by macOS 14.4. I do not know if that is related to this problem, but if it is related, this info might give Adobe and others an angle to try and identify the real cause of this problem. You can follow the links in the article below and see if the other users’ configurations have something in common with yours (for example, using JAMF, Windows Defender crashing CUPS, the CUPS software completely missing, etc.) CUPS is the software that macOS uses for printing, and I think it originally stood for Common Unix Printing System before Apple acquired the software.

Unfortunately, I also can’t reproduce this problem. I have an older Intel Mac on macOS 14.4, and I just successfully printed from Lightroom Classic 13.2 to Epson and Canon printers on the US Letter paper size. So it looks like there may be some other factor affecting this in addition to macOS and Lightroom Classic, such as those mentioned in the article linked above.

I'm encountering the same missing paper size issue and more. Try swapping between portrait and landscape on any paper size. I created a custom 17x25 paper size and did a print and it came out all screwed up - shoved up in the upper left corner with 50% of the cell missing off page to the left. I've printed a 1000 prints just fine and did 15 yesterday that came out perfect. What I did do is upgrade to MacOS Sonoma 14.4 this morning so that's my suspect number one for these issues. Doesn't Adobe test this software with the Apple betas?

C’est exactement le même problème que j’ai signalé le  10 mars 

Print Module not working

Il  faut donc attendre une mise à jour est-ce que Adobe est au courant ?
