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

I'm not a geek so...

I printed yesterday with LRC from an M1 mac to an Epson 3880 and the loss of printer settings made things annoying. This morning I began a printing session, having turned on the printer and then openned the printer settings panel only to find my previous settings had been retained. Well, alright I thought. But sending the image to the printer did nothing. I had disconnected the printer from the computer and forgotten to plug it back in. The instant I connected the two, the previous settings disappeared. 

With my limited knowledge of computers I can't say anything specifically, but to me this appears to be an Apple messup.

I finally got it to change by toggling off en then on "scale to fit paper size" in the print settings / paper handling window. Before, i used the same procedure as you, but paper size always reverted back to A3+ in the print settings / paper handling window.

I'm not quite sure of the sequence of steps you use. I set print size in the Page Setup dialog box, then the same paper size is indicated in the Print Setting / Paper Handling box whether or not scaling is chosen. 

Thank you for responding. The problem persists on my computer, running Sequoia 15.2 and LrC 14.1.1. When i change the paper size from A3+ in the window in the screenshot to lets say A2, press save, then open the print settings window again it is stills saying A3+. In the "Printer" window to the far right it is the same case, and even if I press print from this window having set the correct paper size it prints wrong with the stuck setting of A3+. 

Tried removing the printer driver and reinstalling after rebooting several times. Does this sound like a lightroom or osx bug?

By chance I happen to be at my desk on a snowy New Year's day running various LRC printing exercises. Everything is working regarding paper sizes as I switch from 5x7 to letter to 13x19. .  I canot replicate your sequence of windows Paper Handling --> Destination paper size. In my dialog box it goes from Print Handling to Scale Paper Size to Destination and I do not use paper Size Scaling.  MacMini M2 pro, Mac os 15.2, LRC 14.1.1, EPSON SC P600.

Didn´t work that well after all. Page setup now shows my printer (Epson SC-P900) and all paper sizes. Howewer in print settings --> Paper Handling --> Destination paper size my settings always jumps back to a standard. I have been able to change this a couple of times, not sure how, but currently it is stuck at 13x19". This of course overrides what is set in the page setup window and makes printing impossible (except if the "stuck" size is what you are after). For now i have given up, and reverted to using an old iMac with older osx for printing. 

Recent update to Sequoia 15.2 issued by Apple seemed to have solved the problem. Installed the update and my printer was showing in the page setup tab in the print module, with all sizes available. 

Same problem, tried uinstalling/installing printer driver twice, both with and without reboot. No change, same problem. Running Sequioa 15.0.1 and LrC 14.1.1. Any news on this case, or other possible solutions?

Thanks, your suggestion worked! I appreciate it.

Hello Keylor,

Try uninstalling and re-installing your printer driver. Restart your Mac in between the uninstall and re-install. This worked for me. All the print sizes for my Epson printer are now available again in LrC, as are all the default printer paper profiles.
