Same problems on my WorkCenter 6515. It seems to be a Mac OS Ventura problem ...
Hey all:
I have a Mac Mini M1 running Mac OS Ventura 13.1 connected via Ethernet to a Versalink B7035. After installing and updating the latest print driver for the Versalink, every time I try to change the Print Settings > Paper Source > Tray # from Auto Select in the system print dialgoue box, it will always default back to Auto Select, regardless of whether I select any specific tray and save it as a preset.
I can change the defaul tray in the CUPS configuration page in my browser so that I can control where Auto Select sends the print job to, but I can't save a preset to any specific tray, as it just keeps defaulting to Auto Select. I'm sure there is an easy fix for this, but I simply can't find it after searching online and in my Versalink and Mac settings for the solution.
