Value of n: 

Specified character code.

32–255

Cancels the pattern defined for the character code specified by n. After the user-defined character is canceled, the 
corresponding pattern from code page 437 is printed.

This command is ignored if n is out of range or if the user-defined character is not defined.

Starts or stops emphasized printing on slip and receipt. 

In emphasized mode on the slip, each line is printed twice to improve penetration of multi-part forms and increase 
print contrast. The second pass is printed the same direction as the first to ensure accuracy of the overprint. Printing 
speed decreases due to the second printing pass.

Only the lowest bit of n is effective. 
Emphasized printing cannot be used with bit-images or downloaded bit-images.

This command and the select print mode(s) command  
(1B 21) function identically.

Turns double-strike mode on for the slip station. Overprints a second pass of the print line on the slip station to 
improve penetration of multi-part forms and increase print contract. The second pass is printed the same direction as 
the first to ensure accuracy of the overprint. The printer is reset to the standard print mode after a clear printer (0×10) 
command is received.
