To create negatives (inverted and mirrored), send this PS file (works with a
Linotronic RIP with PostScript version 42 and later):
serverdict begin 0 exitserver
statusdict begin
/negativeprint true def
/mirrorprint true def
end
To return to normal printing (inversion and mirroring off), send this file:
serverdict begin 0 exitserver
statusdict begin
/negativeprint false def
/mirrorprint false def
end
The condition called out will remain that way until you reset the printer, or
until you send the other PS file.
