Recently there was some discusiion on obtaining Win 7 64 bit drivers for doing this.
As I posted before, go to this page http://h30499.www3.hp.com/t5/Printers-Designjet-Large-Format/HP-DesignJet-450C-Windows-7-x64-Driver/td-p/5406627 and scroll down till you find this article and then click on his link for drivers.

For 64 bit systems you can download the XP x64 drivers from here, then unzip the files into a new folder. Next go to the Devices and Printers folder, Add a Printer, select the proper port, then select "Have a Disk" and point to the folder where you unzipped the files.
The other likely issue is finding a proper communication. Most Windows 7 machines do not have a parallel port. USB-parallel converters can be used but many do not work in Windows 7. The models here have been reported by users to work in Windows 7. Another option might be to get a Jetdirect box and install the printe ron a network.

Worked like a charm and as I had a parallel port installed ahead of time I didn't have to get into the next problem of USB issues.
