We have several older HP printers (LJ4000, LJ4050, DesignJet 500, etc). The print server (Windows Server 2003) has the 32-bit drivers installed and I need to install the 64-bit drivers. Easy enough normally when you can download the 64-bit drivers and simply add additional drivers. However, HP doesn't supply these drivers any longer (they are installed via Microsoft Update).
So, without having a driver to install via Additional Drivers, we installed the Universal Driver. This has proven to have been a mistake, because we are getting errors on our printers that point to driver issues - especially printing from CAD programs.
So, the question is, how do I get 64-bit PCL drivers added to the print server when the drivers are not available for download?
