User-Defined Characters; Designing Your Characters - Epson LX-810 User Manual

User-defined Characters
With this printer, it is possible to define and print characters of
your own design. You can design an entirely new alphabet or
typeface, create characters for use as mathematical or scientific
symbols, or create graphic patterns with user-defined characters to
serve as building blocks for larger designs.
Below, you can see sample typefaces created with the user-defined
character function.
You can make the task of defining characters easier by using a
commercial software program that either assists you in creating
characters or just supplies you with sets of characters already
created. Also, some popular cormnercial software programs take
advantage of the printer's user-defined character function to
enhance printouts. (These characters are called downloadable fonts
in some programs.)
The standard ASCII characters are stored in the printer's Read
Only Memory (ROM), and the user-defined characters are stored
in the printer's Random Access Memory (RAM).
Designing your characters
User-defined characters are like dot graphics because you send the
printer precise instructions on where you want each dot printed. In
fact, planning a user-defined character is like planning a small dot
graphics pattern. For simplicity, this section shows you how to
design draft-quality characters. Designing NLQ characters is more
complicated and is therefore described later in this chapter.
