Epson
Printer Control
Codes
Following are control codes for all Epson printers. Some of the functions are not available on all printers, and we've marked them with an asterisk. Refer to your printer's manual to see if it will perform the listed function, or just send the control code and see what happens. (We have not noted with asterisks some functions of which printers are capable, but which may not be available through Epson PICs or other interface devices for certain computers.)
From the BASIC programming language, the function is called with a command like LPRINT CHR$(27)"P"; in other words, placing the command LPRINT before the command shown below. From some applications, the command below can be entered after a symbol that tells the printer a control code is coming.
A lower case "n", as in CHR$(n), means a numeric value must be inserted.
