I've been a long-time user of QImage Pro, and haven't had any issues with it on my present system (Win7 with an Epson 7880) until recently.  About a month ago, I could not make a print at the size that I had specified in the program.  The preview would look correct, but it would print at completely the wrong size.  I think that the aspect ratio wouldn't even stay the same as the original.  For example, I'm printing an image at 20 x 30" on 24" canvas, with a 1.25" border.  I specify the media size in the driver as 24 x 34", and even had the driver generate a print preview before printing, which looks correct, but the print comes out tiny, only about half the size I specified.  I'm burning through a ton of canvas, paper, ink, and time, but still unable to make a print   Any suggestions?

If you think the aspect ratio is off, check the crop scissors button.

Glad to help
