![]() When Windows 8 and greater does not have the Type 4 driver already, it will use the Type 4 Compatibility driver preinstalled to produce XPS for SSR when it gets to the print server. When clients are Windows 8 and greater, when a Type 4 driver exists on the client already, this driver is used to provide Client Side Rendering, CSR, so PDL conversion, rendering, happens on the client. The rendering of the XPS data to Page Description Language, PDL, that the printer understands, PS and PCL, occurs on the print server, Server Side Rendering, SSR. The Microsoft compatibility driver is a Type 3 print driver designed to generate XPS content when the shared printer is setup with a Type 4 driver. ![]() Since Type 4 driver infrastructure changed in Windows 8 / Server 2012, older versions of Windows had no code to handle Type 4 drivers. The print server was becoming a software distribution center and thus the change. The purpose of their development was to provide a less intrusive and easier printer connection mechanism than what occurs with sharing printers with Type 3 drivers. I know this one is solved but wanted to provide context around the use of Type 4 print drivers. Why does 2 windows 7 machines map to the printer on the server and use the MS PnP driver when others just error out? ![]() From what i have been reading there are some issues with Windows 7 and the server downloading drivers to clients. One thing i did see though is that these drivers on the server are v4. ![]() On the server the driver shows as the correct either 4250 PCL6 or 4014 PCL6. When I checked the two computers that currently are mapped to the server with either one of these printers I see that the driver is the "Microsoft Enhanced Point and Print Compatibility Driver" When I try to map these printers to any other Windows 7 machine 2 different errors on 2 different machines The two users that have been using these printers from the old server (2008 R2) I retired a few months ago are working fine mapped to the server. I have some old HP printers the few I am having an issue with are We currently have a printer server running Windows 2012 R2.
