Please take a look at this article regarding printing on Extra Long Sheets (XLS).
I hope this helps.
I am not sure what you would need of if that is possible for that model. But here are the available drivers and downloads for your device.
Is it possible for the press system to be upgraded?
I need to print at 700mm or 27.5". The manual on the page says it is possible to print at 1200mm or 47.25" and it only gives me the option to put 660mm or 26.0". Thank you!
