I believe that I wound up with a newer HP driver. My printer list shows HP DesignJet Z3200ps 44in Photo PS3.
Is this a problem with the print driver, or did I miss something in copying these files?
I've had this happen over the years too.I can make it happen now by selecting an old job or latout that was made when I had an Epson 2000 printer and trying to open it.
The official printer name must match the saved name of the new printer driver.
I haven't messed with a name change in years, but I remember Mike helping me.
So hopefully Mike will see your post and I will experiment here and see if I can fix one here.
How about saving a new JOB and open the subsequent files and see what printer name was used.
