End Double-Strike Print (ESC H)
1B 48
This control ends double-strike printing.
Printable Code Area Expansion (ESC I)
1B 49
This control defines whether codes X'00' through X'1F' and codes X'80' through X'9F' are printable
characters or control characters of the active character set.
When NN equals X'01', the codes become printable characters, which allows them to be used as
user-defined characters.
When NN equals X'00', the codes are returned to nonprintable characters.
Perform n/216 Inch Line Feed (ESC J)
1B 4A NN
This control performs a vertical move relative to the current presentation position.
NN is a one-byte hexadecimal value that specifies the move amount in units of 1/216 inch. The printer will
adjust the value to the nearest 1/144 inch. This control performs an immediate line feed, but does not
affect subsequent line spacing and does not produce a CR.
Select Single Density Graphics Mode (ESC K)
1B 4B LL HH NN...NN
This control prints the supplied bit image data at 60 horizontal pel by 72 vertical pel. Bit image data can be
mixed with text data on the same line.
A two-byte count (LL HH) indicates the number of bytes that follow in this control. LL is the least significant
byte of the count; HH is the most significant byte. (The number of bytes that follow should equal HH
× 256
+ LL.) If the count equals X'0000', the control is ignored.
NN...NN are the bytes containing the bit image data. The data format is in 8-bit vertical slices, with the
least significant bit the bottom dot and the most significant bit the top dot. B'1' indicates a pel to be printed;
B'0' indicates an unprinted pel. Data that exceeds the right margin is discarded.
Select Double Density Graphics Mode (ESC L)
1B 4C LL HH NN...NN
This control prints the supplied bit image data at 120 horizontal by 72 vertical pel. Bit image data can be
mixed with text data on the same line.
