I see that our Hitachi DDP70 printer does print "edge to edge" and the printer properties is set to do so. However, planet press still shows the .25" margin (grey lines) all around an usletter size page. I found what i thought might be the parameters in points for the image area of different page sizes - looked something like: "*Imagablesize 12 15 580 790"

I changed the first 2 numbers to 2 5, started Planet Press and the margins still looked the same. I quite Planet Press and viewd the PPD and it looked unchanged.

1. Why when the printer is set edge to edge PP is not showing that?

2. Is it possible to change PPD like above?

Thanks for your help in advance?
