Escape Sequences
Some KS control codes consisting of more than one character are called escape sequences because the first character in the sequence is the ASCII ESCape character. ESC alerts the printer that a special function command— not printable
The format for an escape sequence is:
ESC (parameter 1)(parameter 2)...(parameter n)
For example, to select emphasized (offset) print, send the ESC character immediately followed by the E character (do not add a space character):
ASCII: ESC E Hex: 1B 45Dec: 27 69
FS Sequences
Another type of control code which consists of more than one character is called an “FS sequence,” because the first character is the ASCII FS character. This control code is used when the printer is printing Double Byte Character Set (DBCS) characters. The FS alerts the printer that a special function command (not printable characters) follows. Most FS commands work only on DBCS characters.
The format for an FS sequence is:
FS (parameter 1)(parameter 2)...(parameter n)
For example, to rotate DBCS characters by
ASCII: FS J Hex: 1C 4ADec: 28 74
