The printer can have a maximum of 10 fonts, including the two
standard fonts (Gothic and Courier) and up to eight optional fonts.
The variable N can be any value in the range of 0 through 9, where 0
designates Gothic, 1 designates Courier, 2 designates the first font in
option ROM 1, 3 designates the second font in option ROM 1, and
so on. The range of N for either option ROM depends upon the
number of fonts contained in each ROM.
Examples. If option ROM 1 has two fonts and option ROM 2 has
three fonts, then the range of N is 2 through 3 for option ROM 1 and
4 through 7 for option ROM 2. If option ROM 1 has four fonts and
option ROM 2 has three fonts, then the range of N is 2 through 5 for
option ROM 1 and 6 through 8 for option ROM 2.
Font Invocation
The Model 880 Printer emulation enables you to define the contents
of the “in-use” font table. The in-use table defines the font currently
being printed. The contents of the in-use table can be replaced
entirely by an alternate font, or individual characters in the in-use
table can be replaced by individual characters invoked from an
alternate font. There are four possible alternate sets, called G0, G1,
G2, and G3.
