Hi Greg
I'm not completely sure what you are doing and what's happening.
But the important things are:
1) I think you are printing with both Epson driver and QTR driver. It's important
with either that you do the paper selection with the driver you are using.
The major difference is that Epson selects the paper feed in the paper size selection
whereas QTR driver does paper feed in the print dialog. You should always
make sure whether it's roll or sheet. The 2 inches lower could be that roll is
selected but a sheet is what you have.
The App you are using to print can be either Photoshop or Print-Tool -- either app
can print to either driver. So the above issue is the same with either app.
2) Custom papers sizes can be confusing sometimes. For sheet paper you almost
always feed shorter side into printer so width is short side and height is long side.
But with roll paper you might do the opposite -- a 20x24 print on 24in roll paper will
be 24wide and 20height for the custom size. It may look as landscape but it's portrait.
The rule is that width is ALWAYS across the printer and height is feed direction.
3) With QTR driver one issue is that if the paper size is too big it reverts back
to letter size. This can give the partial print problem. So with a 7880 you have
24in wide as a max. E.g. if you use metric and make a paper 610mm wide that's
that';s 24.015in which is too big. Also important not to have a borderless paper
from the Epson driver that expands the paper size slightly.

Hi Greg,You are using PrintTool, right? I've seen this before, though it's been a while. I think it has something to do with the relation between Paper Size, Image Size, and margins.Assuming you have already sized the image how you want it in Ps, and that there are sufficient margins for your paper size, make sure that scaling in PT is at 100%. (Seems like that should be the default but sometimes it changes spontaneously.) Then click the bull's-eye (center) button under Position. If you add a margin to the image in Ps (like what we do with PiezoDN to print clear edges) be sure that it is not larger than the paper size - not even by a tiny fraction.I usually use custom page sizes too, and set the margins equal all around - usually zero - but I also never print closer than an inch to the edge so that doesn't really matter. I do notice that there is sometimes a tiny offset (something like 1/100th or less) when using the center button, but that can be overridden by entering the position numbers manually. But this is nothing like the mis-positioning you are talking about.As I';m writing this, I'm starting to think I maybe I haven't had this problem since PrintTool came out. I definitely remember it happening occasionally back when I had a 7600 and was printing with QTR directly from Photoshop on a G4 or G5 running on Leopard or earlier.Rereading this, I doubt it will be of much help, but I'm posting anyway. ;)Cheers,Keith"Ever tried.

It's definately a QTR issue. I print from Photoshop with no problem. I choose letter centered and the sides are ok, but the top is really off. My margins are at .125 on top and the sides and .556 on the bottom.
Does anyone else have this problem?
