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.
