Epson LQ-850 User Manual - Page 96

User-Defined Characters With the LQ, 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 userdefined 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 LQ's user-defined character function to enhance printouts. (These characters are called download characters in some programs.) The standard characters are stored in the LQ's Read Only Memory (ROM), and the user-defined characters are stored in the LQ'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. 4-20
