The poster program that I posted last week can be easier modified for B-size
printer.  I changed the PAGEW to 10.0 and PAGEH to 16.0 and recompiled.  I
then sent the output to a QMS2200 printer.  The tiles came out nicely on
the 11"x17" paper.

The meat of the program is in the PostScript Prolog.  The C program is only
a front end to compute the scaling factor based on desired output size
and also perform the tedious work of outputting all tiles in one job.

You can extract the PS code easily by doing:
	poster dummy-ps-code 7.5 10 1 1 > poster.ps
You can then alter the scaling factor and grid number to output to anysize
you want one grid at a time using the same poster.ps file.  (i.e. The ps 
program can also benefit users who have no C compiler.  If there is enough 
requests, I can post the poster program in PostScript format.)

Question:  How big a scale can PostScript handle?  The poster program in
theory can prepare tiles for bill board size poster.  The only question
is that will the printer be able to print the outrageously scaled up tiles?

Correction:  I suggested to paste the tiles together in a checker-board
manner.  I found that if you clip the top and right edge along the crop
marks and then paste the tiles together in a "fish-scale" manner, your
task of aligning the tiles is much easier.

Happy printing!
