3.2.

Escape Sequences 

Escape sequences, also known as PCL (Printer Control Language) commands, tell the printer which operations 
to perform. An escape sequence consists of the 

Esc

character followed by a string of characters which define the 

operation to be performed. Some escape sequences require parameter values. These are included in the sequence 
as numeric characters. The final letter of an escape sequence must be uppercase: all others must be lowercase.  

You can send the printer instructions by embedding escape sequences in programs or in word processed 
documents. 

In this manual escape sequences are shown as they would be entered, except that the character # in a sequence 
indicates that a number should be included at that point in the sequence. If no number is included, the printer 
interprets that parameter's value as 0. 

When downloading fonts or sending raster scan images to the printer the final uppercase character of the 
sequence is followed by the relevant data. 

Two escape sequences can be combined into one if the first three characters of each sequence (including the 

Esc

character itself) are the same. Hence, 

Esc*c45G

 and 

Esc*c2P

 may be combined to give 

Esc*c45g2P

. The 

uppercase 'G' which terminated the first sequence becomes a lowercase character in the combined sequence. 
Combined escape sequences are executed left to right, so be careful to place commands in the order in which 
you want them to be executed.  

3.2.1.

Line termination

You can set the carriage return, line feed and form feed control codes to perform compound functions. You can 
either do this using the printer's control panel (see the User Guide) or by sending the printer the following 
escape sequence: 

Esc&k#G (27)(38)(107)#(71) 

<1Bh><26h><6Bh>#<47h> 



0 = Carriage return, line feed and form feed perform their normal functions. 



1 = Carriage return performs carriage return/line feed, line feed and form feed perform their normal 
functions. 



2 = Carriage return performs its normal function, line feed performs carriage return/line feed and form feed 
performs carriage return/form feed. 



3 = Carriage return performs carriage return/line feed, line feed performs carriage return/line feed and form 
feed performs carriage return/form feed.
