2-31 PCL

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.

Table 2-9: Control Codes

Code	Dec	Hex	Function	Result
BS	8	08	Backspace	Moves the cursor toward the left margin one horizontal space equal to
				the last printed character
HT	9	09	Horizontal Tab	Moves the cursor to the next defined tab stop
LF	10	0A	Line Feed	Advances the cursor to the same horizontal position on the following line
				as determined by either the Vertical Motion Index (VMI) or Set Line
				Spacing command
FF	12	0C	Form Feed	Advances the cursor to the same horizontal position at the top margin of
				the next page
CR	13	0D	Carriage Return	Moves the cursor to the left margin
SP	32	20	Space	Moves the cursor to the right one column
SI	15	0F	Primary Font	Selects the primary font
SO	14	0E	Secondary Font	Selects the secondary font

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.
