HP Designjet 500, Designjet 800 Incompatible with Windows 11?

If your HP DesignJet model 500 or 800 won't communicate with your Windows 11 (or Windows 10) computer, don't worry --there is a solution! A very helpful customer clued us in on getting the PC to talk to the printer: 

"Below is the HP Support page showing the driver choices (note that I selected Windows 8.0. I chose "HP DesignJet 500 PCL3GUI 64-bit" for my HP Designjet 500 42-inch and downloaded zipped file hpdj500wx64pclen which I then unzipped to a folder on my C: drive. I then went into Windows Setup, connected the plotter to a usb port, turned the plotter on, went through the "add a printer" process, chose to add printer manually which required me to scroll through a list of HP printers (had to update list), then said "Have Disk" and set the directory to the one created earlier and it worked (see test printout). It did take me a couple of hours of failed attempts before getting this process to work."

Note: the driver page will auto-detect your operating system, and show you only "applicable drivers." You can manually change the setting on the page by clicking "choose different operating system."
