The selection of built-in 'page types' has been enlarged to include two
European sizes. The height of the letter and legal page sizes has been
slightly decreased because of memory constraints in the new software.
Finally, the function of the 'note' page type has been generalized.
The LaserWriter includes buit-in device setup procedures for establishing
any of seven standard page types:
1. letter
2. legal
3. A4
4. B5
5. lettersmall
'Lettersmall' is an imageable region 7.68 by 10.16 inches centered
on an 85. by 11 inch page.
6. A4small
7. note
'Note' selects one of the above page types according to the paper
tray that is installed. If the letter or A4 tray is installed, 'note'
selects 'lettersmall' or 'A4small' respectively. If the legal or B5
tray is installed, 'note' selects 'legal' or 'B5'.
For the letter or A4 paper sizes, this has the effect of increasing
all four margins to approximately 0.42 inch. The reduction in the
imageable area frees up as much as 100,000 bytes of memory, which
is added to the VM (Virtual Memory) and made available for PostScript
programs.

Computer, Inc., manual number: 030-1296-B) describes the letter, legal, A4 and
B5 pages sizes.
