1. Open the Control Panel and Devices > Printers and Hardware.
All of the available Roland mills will be listed.
Note whether any setup requirements for CAM software require the machine name to be set per the CAM requirements.
You can google how to change your printer settings if you are unfamiliar with having multiple printers.
2. Right-click on the printer icon for the mill and change the name to the desired name.
Do not use special characters such as *&, ^<>? because they can trip up software not designed to handle them. Keep the printer name limited to alphabet, numeric, dash, and underscore characters.
3. Restart VPanel.
The new name for the machine should appear in the Printers list.
If not, restart Windows and checking if the changes applied.
NOTE: There are known issues with VPanel remembering sometimes remembering old printers with different names. There is no easy fix for this as it's a Windows/VPanel issue.
