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

I don’t know the answer to this, but someone else was just talking about a similar-sounding problem on a different Lightroom Classic forum, with no good answers so far:

https://www.lightroomqueen.com/community/threads/page-setup-paper-sizes-missing.49781/

So it’s possible that there might be a problem in macOS 14, Lightroom Classic, or the printer driver software, not sure which. A moderator might consider moving this thread into the Bugs section of this community.

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.

I can partially get around this with custom page sizes, but I can't trick the printer into doing borderless prints that way.

Thanks in advance for ideas.

Depuis le passage à Mac OS 14.4, le module impression dans LRC ne fonctionne pas correctement.

Ex: Avec imprimante Canon Pro 1000 quand je vais au module impression et mise en page il ne reconnaît pas les tailles par ex A6 avec ou sans marge...pour A4, A3 ,A2 aussi

J'ai testé sur la version précédente de Sonoma il n'y a pas de problème.

Est ce que ce bug est connu
