Epson EscP printer Language summary.
Most commands will work on most epson compatible printers including Star, Citizen, and Panasonic.
Commands cannot be put together like PCL (HP) but rather must be used individually though many times, more than one command can be put on one line. Ec stands for the Escape key chr$(27).
If a code in a sequence is for example 1 (049 or ascii "1") and the command doesnt seem to work, try CHR$(n) instead.
Example: if LPRINT CHR$(27)+"U"+"1" doesn't turn the Unidirectional print ON then try instead, LPRINT CHR$(27)+"U"+CHR$(1). Most (but not all) of these commands will work on proprinter emulation also.
