The master print mode command is one of the MPS 1200's most
powerful commands. With it, you can select most combinations of
print pitch, character width, print quality, and special effects-
using just one command.
The master print mode command is ESC !. As with the master
pitch
command, you select the print mode you want by sending the
ASCII code corresponding to its
print mode number.
Each combination of features on the MPS 1200 is assigned a unique
number called the "print mode number." For example, elite em-
phasized expanded compressed underlined italics, thankfully, is
simply mode 237. To select this mouthful, you can send the com-
mand ESC! chr$(237). Try it with the program below.
10 open1,4,7
20 pt'int#1, cht'$ (27)"! "cht'$ (237)
'c.O pt'int#1, "Wi th master print, thet'e at'e ovet'
100 possible combinations"
4(1 pt'int#1, chr$ (27)"! "cht'$ (0); "And thet'e's always
vanilla, if you like."

Uith .aster print. there are over 100 possible co.binations
And there"s always vanilla, if you like.
The trick to using the master print mode command is knowing the
print
mode number for the combination of features you want. With
over 100 combinations available, learning their numbers is not the
answer.
hHtunately, there is a simple way.
