Hello Patricia, just to make sure of sa few things before I go any further: What model number is the printer?
What operating system are you using?
I assume you've been able to print via Pertax before, and if that is the case, when did you start experiencing these problems?
Have you had any updates to either the programme, your operating system or the printer prior to the printing errors?
Do you or any one else use any other software where you use the printers, and are there any problems with this as well?
Regards
Martin
