[comp.laser-printers] Problems with imageable area of LaserWriter

mario@ux.cs.man.ac.UK (Mario) (03/03/88)

I'm having some trouble getting a number of Apple LaserWriters and LW+s set
up the same, margin-wise.  Most have similar default coordinate systems
but strange things happen when the letter, legal and note commands are
used. 

On p.285 of the PostScript Reference Manual it says (regarding these
commands):

	For all page types, the point (0,0) in default user coordinate
	space is the lower left corner of the entire page, not of the
	imageable region; that is, the origin lies some distance outside
	the lower left corner of the imageable region.  The coordinate
	system is arranged this way so that switching page types does not
	affect the position of graphical objects on the paper but just
	changes the sizes of the margins.

However, when I print a testpage to identify the location of the coordinate
system, it moves to a different place when started with either of these 3
commands (these are all printers fitted with an A4 tray).  Only the note
option centers the imageable area on the page; all of the others are way
out.  

The questions are: does this happen on the US models of LW too? and
Does anyone know of a work-around?
I believe that the "margins" parameters are used globally, so can't see a
way of fixing the problem by using setmargins.
