Lightroom Print Module Error Message

[LenR7]

Greetings.  I just updated my 2019 Mac Pro to Sequoia from Monterey.  I've been printing from Lightroom Classic on Legacy Platine for years with my Epson P900 with no issues under Monterey.  Under Sequoia, after installing the Sonoma print driver from Epson (the Sequoia driver has not yet been released by Epson), all my icc profiles disappeared.  Following Digital Dog's excellent instructions, I found them and made sure everything was installed and they now populate the profile pop up in Lightroom.  However, the prints are not correct, everything is magenta.  I notice an error icon in the print settings box under Media Type; Platine is selected but there is a yellow triangle with an explanation point in the middle.  The error message is hidden by the print settings dialog box, which cannot be moved out of the way. At one point part of two words of the error message were visible, Settings and Etching. Apparently there is a conflict of some kind and maybe the profile for Legacy Etching is somehow creating the issue?  I'm at a loss here, frustrated and tired of wasting expensive paper on test prints.  Any help greatly appreciated!
Thanks,
Len

A magenta cast can indicate that a print is being double colour managed; that is by both the application and the printer.

I have not yet been able to make colour managed prints with confidence in Sonoma.  I have a Canon printer and Canon are investigating.

See: http://digitaldog.net/files/API%20Print%20bug%20in%20macOS.pdf and make sure this isn't the issue. Otherwise, when all is setup correctly and without this bug, I've seen no issues in Sonoma.

Thanks Andrew but I am not experiencing that bug.  Do you have any suggestions regarding my original post?

Thanks,

Len

You can try resetting your print system. On your Mac, choose Apple menu System Preferences (System Settings in Ventura +), then click Printers & Scanners
Press and hold the Control key as you click in the list at the left, then choose “Reset printing system” from the menu that appears.
After you reset the printing system, the list of printers in Printers & Scanners preferences is empty.
Reinstall the print driver from the manufacturer, not Apple.

Andrew, I did the print reset and reinstalled the Epson software using the updater. Now the icc profiles do not appear in the LRC printer dialog boxes.  All the icc profiles are in the location you identified in a different post; I copied them to the color sync folder, restarted LRC and no luck.  I now have an additional problem, the LRC Print Settings box, under paper handling, I set it to 13x19 and hit save, but when I reopen the destination paper size is always 5x8. Just don't understand how everything got so screwed up.  Another thing, the printer driver is 13.26. I had downloaded 13.46 from Epson Europe and installed it but now it is not installing, even though the installation package software says installation successful

Thanks,

Then maybe do the Epson Enema and install the print drivers (from Epson) again: 
   1.   Delete all instances of Epson printers from System Preferences (System Settings in Ventura)>Print & Fax.

   2.   Then go to /Library/Printers and toss the whole Epson folder.

   3.   Toss LFP Remote Panel (IF you are using this utility for your printer).

   4.   Then reinstall drivers from Epson and never Apple.

NOTE: IF you have more than one Epson printer, you need to install the driver in the order of their release! Older then newer or you run into issues (eg, install 4800 before you’d install 3880).

Thank you Andrew.  I did that (deleted all Epson drivers and software), and installed the latest driver.  For those who are having issues, Epson just released a new installer for the P900, the file name is SCP900_Lite_64NR2_NA.dmg.  Even with that, the media was not showing up in the printer options box in LRC, even though all the icc profiles are in the ColorSync folder.  I opened Epson Media Installer, and downloaded and regsitered the media I wanted, and that worked. I'm still getting the same error message (yellow triangle with exclamation point inside) but the colors are now perfect.  Thanks!!
