The fastest solution is as follows:
- Log in as a print server Administrator on a 32-bit server (a 32-bit client machine might work also).
- Browse to your print server's UNC path (\\printserver).
- Open the Printers and Faxes share.
- Right click on the printer you wish to add 32-bit drivers to and click Properties.
- From this point, add the drivers just as you normally would. It shouldn't give you any NTPRINT.INF issues!
