Downloading
Characters and
Fonts
This chapter explains how to download characters and provides programming
examples for several escape sequences. The first part of the chapter is for 248x
users; the second part is for 249x users.
The downloading feature lets you create custom fonts and special characters.
You can create and print complete italic or foreign language character sets as
well as symbols and special characters not in the printer character sets.
The examples in this chapter use the BASIC programming format shown on
page 16.

Designing Draft and NLQ Characters

For Draft and NLQ (Near-Letter Quality) characters, the 9-wire printers use a
character matrix that is 12-dots wide and 9-dots high. Ascenders generally use
the top 7 rows, establishing row 7 as the baseline. Descender characters
generally use the bottom 7 rows. For uniform and evenly spaced characters,
each character should be 9-dots wide and start in column 1.
How Dots Are Added in NLQ Mode
The 9-wire printers can print downloaded draft characters in NLQ mode.
Downloaded characters print at the same speed as standard characters. You
design the characters for Draft and the printer adds the additional dots to each
character when printing in NLQ mode.
