Pressed the paper settings dialog from qimage, pressed properties, paper layout and set the size to 3900*2800 mm with rollpaper as source. When I return to the dialog, it has returned to the old size settings and won`t listen to any of my input...
When I set to metric and go into the printer driver, it does not allow 2900. It asks for a decimal point inserted.
Max width appears to be 432.0 mm
I don't know what print size as I am dumb when it comes to converting inches to metrics, but I just think you are nit inserting the User defined size properly.
Recheck the User defined box and have a closer look.
I will be out for an hour.
Maybe Brian or Terry can work the metrics with you.
When I convert to US units I see a 17 inch roll
