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 special applications such 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 samples of typefaces created with the
user-defined character function.
You can make the task of defining characters easier by using a
commercial software program that assists you in creating
characters or simply supplies you with sets of characters
already created. Also, some popular commercial software
programs take advantage of the printer’s user-defined character
function to enhance printouts. (These characters are called
download characters in some programs.)
The standard 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.
