User-defined Characters
The command format is:
ESC : 0 n 0
Note: This command will cancel any user-defined characters you have created. You must send this command to the printer. before you define characters.
If you use this command at the beginning of a program, then define your special characters and select the user-defined character set, you can print with the user-defined character set as your normal character set. You never need to switch back and forth between sets.
Mixing print stylesThe user-defined character set can be used in combination with most print styles. For example, emphasized and double-wide printing both work well with user-defined characters.
The sample below shows the heart character printed in two different styles.
Keep in mind that user-defined characters are stored in RAM, which is not permanent. Whenever the printer power is turned off or your computer sends an initialization (INIT) signal, all of the user-defined characters are lost. (Some computers do this each time BASIC is loaded or when certain application programs start up, and most computers do it if you have to reset them.) If the program resets the printer with the ESC @ command, the ROM set is selected, but the user-defined characters are not lost.,
