.... so the PC's driver name matches the driver name on the print server (allowing us to map that printer on the PC) for some reason Windows 7 "Add a Printer" wizard (where you select the make and model of the printer to add) is still showing the OLD name "HP LaserJet 4200/4300 PCL6", even AFTER the .inf file is changed and the print spooler service is restarted.
What is the trick these days? We can't change the print server, so the naming change has to be made on the client PC. But our changes to the INF files are NOT being reflected in the list of available print drivers in the Add/Remove printers applet.
"HP LaserJet 4200/4300 PCL6" = hpmcpap6.gpd.Win7,Hewlett-
It appears twice and should be modified twice.
When you're done modding it, delete the .PNF file right below the INF in the same folder.
Try again to see if it is correct.
