Stephen,

I was afraid you would ask that :-)  

There's no way to get that information from the printer I guess and 
there are odd formats around. But if you stick to the sizes that are 
commonly used on Epsons:  44" - 1118 mm (QTRgui says 1117), 36" - 914 
mm, 24"- 609 mm, 17" - 430 mm.  When the width size set for the paper 
comes close to those numbers and media = roll then you can let the 
driver assume that the paper width falls in the width of the roll. 
QTRgui uses 3.4 mm at the sides for the 9000's margin, so a 0 -10 mm 
margin downwards for paper size that has to fit. It will still have some 
problems but I guess in 90% of the cases it will work.
The condition: Media = Roll should at least take conflicts away in sheet 
feeding.


I have not checked the way the direction arrow works with sheets but for 
speed you better use paper with its widest dimension parallel to the 
head stroke direction (if that fits the printer), at A size ratio of 
1.41x it will speed up printing with 20%. There's probably more paper 
waste though. That differs per printer.
