Postscript is optional (497K17810) on the 7035, it appears you didn't buy one, so you will need to use a PCL PPD
And neither Xerox nor Apple releases them, so you may need to use other resources
Thank you for using the Support Forum. Please try the Linux Intel drivers on the support page for your printer. Make sure you have followed the instructions in the solution for installing the Linux drivers. If this does not help then please consider contacting your local support centre.
We purchased a Xerox VersaLink B7035 with a formatting tray for a school set up with a Linux CUPS print server and macOS clients.
I've tried all the drivers including the Windows EXE that houses the General PPD but I get 2 pages spit out after the print job with the following errors.
