Many of the print drivers today are only provided by Microsoft instead of the vendor’s website. Setting up new printers with the add printer wizard will download drivers for whichever architecture the server is running (x64 or x86). This can cause problems for clients on different architecture than the server when they try to connect to shared printers. The client will say that a suitable driver could not be found. [more]
In order to add both types of print drivers to the print server to support all clients, use another dissimilar client and create local temporary printers using LPT1 port for each printer that needs drivers. Make sure to click on the “Windows Update” button when you are adding the printer, and it will pull in a much larger list of printers to install. Chances are the print driver you need will be listed. Finish installing the printer locally.
After you have the 32 bit or 64 bit drivers you wish to add to the print server, browse to the print server (\\printserver) and right click the printer to select the properties. On the sharing tab, click on the “Additional Drivers” button. Check the box for the x86 or x64 drivers that you have already previously installed on the client you are connecting from and it should upload the drivers to the print server for all clients to use going forward.
