O16 bit repeating compressed data

When the most significant 3 bits in the first 2 bytes are in the order 1, 0, 0, the remaining 13 bits indicate the number of times to repeat 16 bit data. The following 2 bytes should be the 16 bit data to repeat.

15	14	13	12	0
1	0	0		number of repeats(13 bits)
O				data to repeat(16 bits)

8 bit repeating compressed data

When the most significant 3 bits in the first 2 bytes are in the order 1, 1, 0, the following 5 bits indicate the number of times to repeat 16 bits (two by 8 bits) data. The remaining 8 bits should be the 8 bit data to repeat.

4 bit repeating compression data

When the most significant 3 bits in the first 2 bytes are in the order 1, 0, 1, the following 4 bits indicate 4 bit data to repeat. The remaining 9 bits indicate the number of times to repeat the 16 bit (4 by 4 bits) data.

Vertical repeating compressed data

When the most significant 3 bits in the first 2 bytes are in the order 1, 1, 1, the remaining 13 bits indicate the same data words as in the previous line.

15	14	13	12	0
1	1	1	the same data words as in the previous line (13 bits)

The printer can not support the APT and HRC function in the 1200 dpi printing mode.
