ESC [ A n1 n2 m1 m2 m3 m4 
Triple Height/Width | Hexadecimal code: 1B 5B 41 04 00 00 00 m3 m4 |
Sets triple height and/or double width for the characters printed, with or without changing the line feed.
Parameters n1 and n2 indicate the number of bytes that follow and have the following fixed values: (4)D and (0)D respectively.
These two parameters are followed by four bytes (from m1 to m4) which have the following values:
Parameters m1 and m2 have a fixed value: (0)D.
Parameter m3 defines the height of the characters and the line feed according to the decimal values in the table below:
m3 Line feed and height of characters
0No change with respect to the current settings
1Unchanged line feed, normal height
2Unchanged line feed, triple height
16Single line feed, unchanged height
17Single line feed, normal height
18Single line feed, triple height
32Double line feed, unchanged height
33Double line feed, normal height
34Double line feed, triple height
48Triple line feed, unchanged height
49Triple line feed, normal height
50Triple line feed, triple height
The top half of the byte indicates the line feed (unchanged, single, double, or triple); the bottom half of the byte indicates the height of the characters.
Parameter m4 defines the width of the characters according to the decimal values in the table below:
m4 Width of characters
0Unchanged width
1Normal width
2Double width
3Triple width
The top half of the byte is ignored, while the values of the bottom half of the byte are significant.
