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. If Automatic Carriage Return on Line Feed is set in the operator
panel Configuration Menu, a carriage return is also performed when a Relative Move Baseline code is
received (see “Carriage Return (CR)” on page 5).
Normal Density Bit Image Graphics (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 un-printed pel. Data that exceeds the right margin is discarded.
Dual Density Bit Image Graphics Type 1 (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.
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 un-printed pel. Data that exceeds the right margin is discarded.
Begin Skip Perforation (ESC N)
1B 4E NN
This control sets the number of lines to be skipped at the bottom of each page. Once this function is
activated, it stays active until the End Skip Perforation (ESC O) or Set Page Length (ESC C) control is
received or the printer is initialized.
NN is a one-byte hexadecimal value that specifies the number of lines to skip at the bottom of each page.
This value must be zero or greater and less than the length of the page in lines (from 0 to 255). Once
Begin Skip Perforation is activated, the number of lines that may be printed on a page is the page length
minus NN.
End Skip Perforation (ESC O)
