Abstract

Certain text formats, for example Postscript (extension .ps) and Adobe
Acrobat (extension .pdf) specify exactly the page layout of the printed
document. The commonly used paper format is different in America and the
rest of the world. America uses the "Letter" format, while the rest of
the world uses the "A4" format This means that documents formatted on
one continent may not be printable on another continent. This memo gives
advice on how to produce documents which are equally well printable with
the Letter and the A4 formats. By using the advice in this document, you
can put up a document on the Internet, which recipients can print
without problem both in and outside America.

Introduction

Certain text formats, for example Postscript (extension .ps) and Adobe
Acrobat (extension .pdf) specify exactly the page layout of the printed
document. The commonly used paper format is different in America and the
rest of the world. America uses the "Letter" format, while the rest of
the world uses the "A4" format.

The American Letter format is 8.5 x 11 inches (215 x 278 mm) while the
ISO standardised A4 format is 210 x 297 mm (8.27 x 11.69 inches). The
Letter format is thus 5 mm (0.19 inches) wider, while the A4 format is
19 mm (0.75 inches) taller.

This means that documents formatted on one continent may not be
printable on another continent. It is oboviously desirable that
documents put up on the Internet are printable on all continents. This
paper gives advice on how to achieve this.


Temporary note

This version of this Internet draft is based on the author's experiments
using Microsoft Word and Adobe Acrobat on a Macintosh computer. I would
appreciate if people who use other platforms and software could test if
my advice will apply also to their software.

              (upright,    inches) to the     0.82"  0.82"  0.59"  0.59"

Letter        Landscape    Add 6 mm (0.2      15 mm  15 mm  21 mm  21 mm
              (lying,      inches) mm to the  0.59"  0.59"  0.82"  0.82"
             vertical)    top of page and
                          bottom of page
                          margins

The reason why you have to add 20 respectively 6 mm to both the top and
the bottom margin is that you do not know what kind of printer the
recipient uses, and different printers feed paper in different ways,
requiring the margin to be added either at the top or the bottom of the
paper.


Method 2: Print with reduced size

This is a method useful for the recipient of a document with the wrong
paper size: The recipient sets the printer to print with reduced size.
When the sender produces the Acrobat or Postscript files, the sender
should "print" with 100 % size, but when the recipient prints the
Acrobat or Postscript files, and if the program for printing Acrobat or
Postscript files allows this, the recipient should print the document
with 92 % or less of full size. Many programs for printing Postscript
files do not allow this. In that case, the recipient can convert a
Postscript document to Acrobat format and then print it with the Acrobat
printing program. This requires, however, that the recipient has the
Acrobat Distiller program, which is not freeware.
