Digital BW, The Print

Stephen,

With the Epson 9000 I have top and left margins of 3.2 mm in QTR. 
Sometimes the left margin jumps to 14.1 mm. I guess that's actually  the 
bottom margin as I need 17,3 mm page size extra for top to bottom 
compared to the image. With the Epson driver I can get less waste on the 
bottom when I set the 9000 firmware to the minimum waste. How well this 
translates to other drivers isn't clear, the Wasatch SoftRip takes other 
margins as well.

What could be the minimum paper waste with QTR in roll printing on the 
9000 and the other printers of that generation?

Regards, Ernst
