Thank you Cathy0.
The CUPS for the 6250DP works well but there is no mention of a ColorCube or 8570 on the3 other package. Maybe there is another printer name/number that is the same?
EDIT. Looks like I may have found it. I will try and report back.
I don't know much about Linux, but I found these drivers from our Support page. They are a little old, so not sure if they will work with your system or not:
I have just set up Linux Zorin 15 (Ubuntu 18.04) and I need my printers.
Neither of my printers are listed in the default so need to get the drivers down.
I do have both IP numbers for my LAN if that helps.
Can you help me please?
