No, maybe I did not describe what I want to achieve accurately; I do not want the output to be scaled, but to be printed in the exact requested millimeter-size. I got it now though that this can be achieved by setting the pagex and pagey values accordingly; I gather that for an A4 page this should be approx. pagex=298, pagey=421 with pageanchor='center'. For some reason here this is still a little bit off, but maybe this can be blamed on the worn mechanics of my cheap old printer. Or maybe the printer has some sort of hard-wired margin on each side that it cannot print on and that ought to be taken into account (if the users only knew about it). Anyway, I wasted some paper and found that for this particular printer values of pagex=290.2 and pagey=419.5 seem to be as close to perfect as it gets with that sort of hardware. Thanks again, and have a nice day :) Michael .-.. .. ...- . .-.. --- -. --. .- -. -.. .--. .-. --- ... .--. . .-. History tends to exaggerate. -- Col.
