Puzzled, I uninstalled QTR and then reinstalled the latest version. I should note that despite the warning that all settings would be cleared by uninstalling, this didn't happen. The ink and file settings from the uninstalled QTR were there on the new installation.
Anyway, the new installation seemed to work yesterday but the problem of an incomplete, faded lower image has recurred.
When this first happened I made a test print simply using PS and not QTR, which produced a correctly sized image.
I'd considered reinstalling the previous QTR version but hoped you folks could help me from just casting about in the dark.
Thanks
