Appreciate the reply @AJPinto !
I did do a full snapshot, as well as the fsevents based snapshot in Composer to build my package that failed to grab everything at deployment. I remember the days where this was common to do as well (been using Jamf since version 6 (2005) ) and preferred not to do it back then thanks to vendors non-compliant installers. It had a lot of components from /Library/Printers in there, so I was hoping it would work. Hope we are not going back in that direction...
My educated guess, without spending hours of wasted time troubleshooting, is that because I'm installing multiple Epson printer driver packages onto the same computer, something may be overwriting or breaking when different versions of the driver are installed using my snapshot package along with Epson's packages for the other models at the same time. I'm sure I could debug it, or capture all the printer drivers (3800, 3880, P800, P900) into one snapshot package that probably compensates for that variable, but would prefer not to do that. It looks like @YanW was able to provide me the guidance below that Epson support could not.
