Fonts and Character Attributes on the LA600 MultiPrinter

19.5 Attribute Selection

The LA600 MultiPrinter supports the SGR attributes underline, overline,

double underline, strikethrough, superscript and subscript, bold, and slant by

algorithmically transforming the characters. The bold attribute, the various

line attributes, and the superscript and subscript attributes, are each applied

with one pass of the printhead. The combination of these attributes results in

multiple passes.

The bold attribute affects the line attributes. The LA600 MultiPrinter does not

apply slant or script attributes to full cell or component characters.

Note

Full cell characters use the whole height of the printhead (all

needles are used) to build a character.

Component characters are used for constructing larger

mathematical symbols such as large integral and summation

signs (some of which are full cell characters).

See SGR in the Command Dictionary.

19.6 Character Size Selection

The LA600 MultiPrinter supports characters in point sizes 10, 12 (Orator-

C), and 54 (Data Block), a ‘‘point’’ being 1/72". Additional character sizes

can be produced via the Graphic Size Modiﬁcation (GSM) command. The

GSM command can be used with both ﬁxed and proportional spacing and all

typestyles, print densities, and character attributes.

As described in Table 19–5, GSM modiﬁes the size of the characters, including

Data Block, by a factor of from 1 to 4 in height and width. The width

multiplier affects the horizontal pitch, which is deﬁned by the Set Horizontal

Pitch (DECSHORP) command, by the same factor. The height multiplier,

however, does not affect the vertical pitch deﬁned by Set Vertical Pitch

(DECVERP).
