We would like to test "KONICA MINOLTA C3850 Series PCL6" version 3.1.2.0 x64 driver and print server already installed with Version 3.0.1.0 x64. If we try to add new printer driver on the print server it is automatically upgrading the driver version and all printers getting new version.
Is there any way that I can add new driver version (without upgrade) in the print server so that I can change one printer to that driver version and user can test it?
