Mac OS Ventura - Why is PPD for printer grayed out?

Mac OS Ventura - Why is PPD for printer grayed out?

I have not had an easy ride with printing connectivity on Mac OS Mojave, and now Ventura, with my little Xerox B205.

Well, I THOUGHT it was as ‘easy as cake’, when I first hooked it up on a MBPro late 2013. The printer displayed via Bonjour and connected in seconds. But maybe a year later, I started getting an ‘AirPrint encryption credentials expired' and I could no longer print. And yeah, I did the dance of trying to create new certificates on the printer. I REALLY tried. NG

Eventually I set up printing on the 2013 MBPro Mojave as LPD, using a Xerox generic model C310 PPD.

Now I have a newer Macbook Pro, 2019, with Ventura 13.2.1

I first setup the Xerox on this 2019 Macbook using ‘generic postscript’, but that configuration does not allow me to choose envelope sizes when I am in the print dialogue.

So I grabbed the same Xerox generic driver (C310) as I used on my other machine, but when I went to add a printer using the Xerox PPD in the Linux folder, it’s GRAYED OUT.

I searched online and found a thread on Spiceworks, where someone said, ‘try putting the .ppd file in Users/Shared’

So I moved the folder to my User/Public folder, and THAT SOLVED IT.

What has changed in Ventura that makes me go thru this ridiculous dance?

Also, when I downloaded and unzipped a file from Gmail with a bunch of .png images of envelopes that I print frequently, when I double-clicked on a .png file to open it, the OS said 'NOT FOUND.

??? I’m looking at the file in Finder, unzipped & dragged right into my Docs folder, but Venura tells me ‘NOT FOUND’. Only when I open Preview 1st, then nav to the file, can I open it.

I checked Info on the file - sure enough, Preview IS the DEFAULT app to open .png files.

This is a weird OS. I am definitely going to update to the latest Ventura after I finish this post.
