This bitmap has a fixed size set by default, tray function, or framedevice (which is set by tray). The size of this bitmap is limited by the printers memory and what operators are available to change it. By default this is set to have a margin of 1/4" on all sides of whatever the page size is. The coordinate system is from the bottom left corner of the page. This means that only those coordinates within the box defined by 18 , 18 x 595 , 775 will actually be on the paper. There are in some (most?) printers a command that will move this printable area around (very small amount) in order to handle misallignment of the paper feed mechanism, this does not generaly allow you to move the region as far as the edge of the paper. Even so you will at best be producing copy that only reaches two ajacent edges at once, not extending the printable area. Mind you, even if you do get the imaging area to increace you will bump up against the physical limitations of the printing engine that the 1/4" margins were to handle consistently for all printers. With regards to the use of A4 paper i'ts not quite what i want to hand someone nor is it readily available (from what i've seen). My recommendation is to print a reduced image with cut marks and then photo-copy it with enlargment or print on 11x15" or some-such with cut-marks. By the way: I agree that this is an irritating hurdle and we need to press the printer manufacturers to improve their engines. ------------------------------------------------------------------- The views of my employer do represent those of myself By de
