Printing to scale. Answered
I often want to print a diagram to scale. Often times the diagram is also larger then the sheet
of paper. ( A sample diagram is at:
. If you want to see other similar diagrams you can look at:
Though not all the diagrams I want to print are boomerangs.
I am using Debian Etch, Cups, Gimp to modify the images which I save as postscript then print via lpr.
My printer is a Lexmark Optra E312L, which can handle both pcl6 and postscript.
I print the diagram once, measure something and figure the scaling factor. I then use Gimp to scale.
Sometimes I just save and print sometimes, sometimes I break it up into overlapping parts and print.
In either case the result is the same. Either the diagram gets shrunk to 1/4 it's size ( even though I blew it up), or the daigram it off by a bit, no matter how I tweak. it seems not to be predictable either. Worse when
I try to line up two overlapping printouts the size don't match, so I can't really join them.
Can someone show how to use Gimp, cups and a postscript printer to print something to scale. From everything i read I should be able to do it, but I guess there is some piece of software in the process that
is saying "Guy is too stupid to print it up right, I have to rescale for him".
