I'm an experienced user of Epson3880 and Canon1000 but new to the Epson P5000. I'm having two problems printing on 17" rolls. I print from Lightroom Classic, current version, from a Mac.
First, the paper size comes up short. For example, I've specified a custom 17 x 28.75 sheet, and I get a 17 x 27.875 sheet. Almost an inch short. I've tried this with several other custom sizes. The top, left, and right margins are accurate -- just the bottom gets chopped. The shortage seems to vary somewhat.
Second, I'm trying to make 11 x 17 prints, using the 17 width efficiently. But every attempt has printed "portrait", with 6" of blank wasted space to the left. I think I've tried every permutation of standard and custom sizes, portrait and landscape. I've even tried 11.25 x 17 to see if that mattered.
Any advice?
