The following four examples get you started. The first is an example of designing and downloading a monospaced Fast Draft character with compression. The second is an example of designing and downloading a draft character without compression. The third example illustrates how to design and download an LQ proportional character with compression. The fourth example shows how to design and download an ELQ 10 cpi character with compression. A description of downloading an entire font is in the following examples.

Designing Monospaced Fast Draft Characters

When designing monospaced Fast Draft characters, design the character for 10 cpi output and use as many dot-columns as possible.

Start with a grid that is 9 dots wide by 24 dots high. Although the character matrix is 10 dots wide, column 10 must be left blank.
