To  print two pages of output side to side, in landscape mode, on
the same sheet of paper, you must of course reduce their size; PF uses
a  trick  to  solve this problem, using reduced side fonts (Courier at
16.67  characters  per  inch),  that only works on the A4-sided paper:
i.e.   only  for the european owners of an Hewlett-Packard DeskJet 500
printer.

     In  order to program a general solution (for every page size, and
for  every printer) you need a way to scale a printed page at whatever
ratio  is required:  this is (by definition) possible using PostScript
(tm)  printers.  But PostScript emulators are widely spread around the
Amiga  community,  e.g.   Post  1.6 (Adrian Aylward is the author, and
Post  can  be found in the Fred Fish collection on the disk 468), that
can  output  PostScript  code  to  whatever printer is defined in your
AmigaDOS  preferences:   so  that  we  can say that a general solution
exists in the Amiga world.

     The  enclosed  file  TwoUp.PS contains the PostScript commands to
print  side  to  side two reduced pages on the same sheet of paper; it
must  be  included  at the beginning of the PostScript file containing
your  output.   PostScript  files  are plain ASCII files, and so every
editor can do this.

     If  you  are an AmigaTeX user, or if you use dvips by Tom Rokicki
(also  called Radical Eye Software) in every other environment, \input
epsf.TeX  (or  declare  epsf.sty  to LaTeX); then include in the input
file a statement \special{header=twoup.ps}.  That's all.

     Logically,  the  two-up  printing is a decision that concerns the
printing stage (dvips) and not the typesetting stage (TeX); if you are
using  dvips  on  an  Unix  (tm)  machine, do not include the \special
statement---but use the command dvips -h twoup.ps .  That's all.

     I  have found TwoUp.PS on usenet (comp.sys.text.tex):  the author
is  quoted  in  the header, and is Walter Neumann of the Department of
Mathematics  at  the  Ohio State University; I have hacked the file to
have  three  sets of constants:  A) to print two 'letter' (8.5" x 11")
pages  on  letter paper; B) to print two letter pages on A4 paper; and
C)  to  print  two  A4  pages  on  A4 paper.  Choose what you want and
comment the other two sets (a comment in PostScript begins with a %).

     I am in no way connected to Adobe (the makers of PostScript), and
only enjoy PostScript programming; I am in no way connected to Radical
Eye  Software,  but only a VERY VERY satisfied user of their products:
THANKS TOM!  Post is not a commercial product, I don't need to include
a  disclaimer  for it:  but I want to thank Adrian Aylward too for his
wonderful  interpreter,  that  allows to use PostScript on every Amiga
printer.

              Happy printing...
