Re: You mean the PPD?
well When I had that exact issue I spent a lot of time in the ppd file itself for the (car sized lexmark) found when I changed the driver to generic postscript the problem went away. Inside the ppd you have
*PageSize A4/A4: "<</PageSize[595 842]/ImagingBBox null>>setpagedevice"
is yours the same?
thanx,
