One of the applications I'm interested in playing around with generates
maps.  I'm interested in blowing the maps up by a factor of 2 or 3
during the printing process and getting everything I've painted on the page
printed out.  I.e.  doing a "scale 2 2" and getting 4 physical pages
to print out.

Perusal of the postscript reference manual suggests that "banddevice" and
render bands may be the appropriate set of commands to look at.  U
Unfortunately, the included descriptive text is very sketchy, and it
also says it requires the use of a device dependent set of commands
to do some of the low level work.

The printer I have to work with is a TI Omnilaser.

My only other alternative is to download the data to the printer 4 (or 9)
times and scaling and transforming and clipping to print 1/4th of the page
at twice the size.  Considering the maps I am talking about are 100K bytes
each, I don't really like this idea.

Has anyone experience with fooling with the "banddevice" routines?  Or,
failing that, has any one got a way of taking "device space", saving
it, clipping portions of it, and transfering a scaled up portion to
the physical page?
