I'm using Dymo Labelwriter 400 Turbo printers in my offices to print labels from a Windows 2003 Terminal Server. Dymo printers are connected to client workstations. Everything was fine until I had to purchase a Dymo Labelwriter 450 turbo to replace a failed Dymo Labelwriter 400 Turbo. This requiered an driver update on the Client workstation and The terminal server. Appearently the 450 driver has files in common (but different versions) than the 400 drivers. When I add the 450 driver (driver only) to the Terminal Server, my 400 printers nolonger print properly. If I reinstall the 400 driver, the 400 printers print properly, but the 450 does not. I recommended purchasing a used 400 to solve the problem, but management doesn't want to go that route. Any suggestions to make the 2 drivers coexist harmoniously on the terminal server would be greatly appreciated!
