Command Structure
This section introduces the different types of PCL emulation commands and their 
structure, or syntax. It also demonstrates how you can link commands to abbreviate 
them.
Control Codes
Control Codes are single-character instructions. 
Commands
PCL commands are multibyte strings (also known as “escape sequences”) that begin 
with the Escape control code (
ESC
, decimal 27, or hexadecimal 1B). The 
ESC
 control 
code notifies the printer that the characters that follow are to be interpreted as part of 
a command and are not control codes or data to be printed.
