My MS1 chip Mac with Adobe 2025 Photoshop CC will no longer work with my Canon Pro-100 printers

Adobe CC forced me to update to Photoshop 2025 recently and then Print Studio Pro vanished. I tried every single thing mentioned on Canon community boards, right down to re-installing Photoshop 2023 from Time Machine, re-downloading fresh PSP software for my specific OS from the Canon website, dragging the PSP files from one folder to another in Photoshop (based on various suggestions of which folder they actually belong in), and nothing works.

I did get PSP to work for one print only when I first moved the PSP files into the "Plug-In" folder, but the next day, upon loading, Adobe gave me a pop-up window asking if I "wanted" to re-install plug-ins and when I clicked "yes," it deleted them instead.

Now, after reinstalling the fresh PSP software for my particular OS (Ventura 13.1) on my computer and then dragging those files into "Plug-ins" (I tried both Photoshop 2023 and 2025) and (based on one suggestion here) trying to drag them into the "Generator" file under "Plug-ins," PSP opened, but then immediately gave an error pop-up window and closed.

And now, even that has stopped, and PSP doesn't show up at all under "Automate."

Adobe won't help at all, they say to contact Canon. Canon customer service now seems to be mostly these boards. I have several Pro-100's plus ink that were all still working great, but I can't use them at all. Can anyone help? Canon "experts"...?

If the Canon Pro printer line won't play nice with Adobe, what is the point of even owning them?

Print Studio Pro has not "vanished". You can find it here: https://support.usa.canon.com/kb/s/article/ART172390. All the software and drivers are here: https://www.usa.canon.com/support/p/pixma-pro-100. The page has a number of software components. You should probably un-install everything to do with Canon printing and install a complete fresh set of software and firmware. If you still can't get it to work and Canon tech support can't help you directly, you may want to think of buying an Epson P-900 and using its Epson Print Layout software (bundled) which is similar to PSP and plays well with Ventura, Photoshop and Lightroom.

Thank you, that worked! I re-installed all of the software/firmware updates from the Canon Pro-100 website page (not just the "Print Studio Pro" file alone, which I had already tried). 

Oddly, the Canon "install" function did not recognize Photoshop 2025, but it did install the updates into the Photoshop 2023 version I had just re-installed on my Mac. So I copied all the newly downloaded PSP files from the "Plug-In" folder in PSP 2023 into the same folder in PSP 2025, which finally worked.

Thank you again for your help (and I will look at the Epson P-900 too).
