Graphic data – non-compressed
ASCII
Hex
Decimal
n: [0;255]
X=54 for FTP624MCLxxx, X=72 for FTP634MCLxxx,
When the printer controller receives this command the
X graphic bytes (d1-dX) will be printed in one dot line.
The MSB in d1 is the left most dot and the LSB in dX is
the right most dot.
Graphic data – compressed

Y: [-X;-2]
n: [0;255]
X=54 for FTP624MCLxxx, X=72 for FTP634MCLxxx,
When the printer controller receives a byte that is –Y to
–2 (Decimal 256-Y to 254) the following data is
compressed data. The number of compressed graphic
bytes is the negative value.
This means:
If Y = -10 (Decimal 246) the next 10 bytes is
compressed data.
The compressed data is as follows.
When a data byte is 0 (no dots activated) the next byte
received is the number of bytes that are 0. All other
data is send as non compressed.
A very few lines cannot be compressed. These will if
you try to compress them be longer than the non-
compressed line. These must therefore be send as
non-compressed data.
