remove Xerox printer drivers to reload old versions
I have Xerox Printer Drivers 3.9.0 on my Sierra Macs, and unfortunately, they won't allow for proper printing with the with Multi-Function devices (ColorQube 9203, etc.) in the office. Basically if I use the driver, I get gibberish (it doesn't process the print job). If I select a generic Postscript driver, it prints, but I lose out on the advanced features - such as selecting paper trays, staples, three-hole punch, etc.
I need to reverse or downgrade the software update to this driver to the previous version that I believe is in the 4.1 Xerox Printer Update that Apple provided (not the version that Xerox provides on their website) in order to get the system to work properly.
Any ideas on how to completely remove the Xerox Printer Drivers from my Sierra system, and then use the PKG installer from Apple to install the "current" Sierra supported version that worked? Resetting the Printer System isn't the answer - and I can't find anything in the library looks remotely familiar (like PPD files, etc.).
Thanks in advance!
