Dan,
I tried your recommendations but I am still not able to print to the edge of a roll with my 17" printer. I'm printing on Epson Exhibition Canvas Matte and when I select "Roll-Borderless, Auto Expand" or "Roll-Borderless, Retain Size" and with the "Zoom to Fill" checked my printer reports that I can't print borderless with the media I am using!
In my custom size for the roll all margins are set to 0".
I also tried making the roll size a custom size of 17.25" to see if that would somehow overcome the 1/8" borders but same thing occurs;) Is there, perhaps, another brand of roll canvas that would allow borderless printing?
Any other ideas from anyone? Sure would be nice to print to 17" width on my 17" printer. I must still be missing something because Roll printing is the only time I have an issue of it not printing to the exact size I specify.... I'm printing from Lightroom.
Regards,
Ron
