If you don’t explicitly indicate what attributes you want for the primary or
secondary font, the printer will use the same default font for both. This
default font’sattributes include the Roman-8 symbol set, 10-pitch spacing,
12-pointheight, upright style, medium weight, and Courier typeface.
After yourprimary font is selected,you can choose it forprintingby sending
this Shift In controlcode:
<S1>
All the text you send after thatcommand will print in the primary font.
Your laserprinter shifts to the secondary font when you send this Shift Out
code:
<so>
4.5.3 Assigning font ID numbers
The secondway to define and select fonts is by usingfont ID numbers. You
mayprefer this method if you frequently use many fonts. While not as short
as<S1> and<SO>, it’s quickerthan describing font attributesover and over
again.
To givean ID number to an internal or cartridge font, you first make it the
primary font. That is, you send aleft-parenthesis Escape sequence (a font
attribute,commandas described below) and the Shift In control code. Then,
to assign an ID number to the font, you send thiscommand:
<ESC> *C HD
Fornyou canenterany numberbetween Oand32767as thefont ID number.
(Not that you can have more than 64 fonts in the printer at once, even with
theoptional memory board. Aprinterwould need an elephantine memory to
hold 32767 fonts!)
