1:1 Aspect
Ratio:
When this aspect ratio
is
selected, the printer
assumes a horizontal and vertical dot density of 240 dpi. The bit-
to-electrode assignment is given in
the
following table. At this
aspect ratio, a data byte would use only 8 of the 40 available
vertical
printing electrodes. To improve performance and
reduce
ribbon
usage,
four consecutive ESC Z commands will be
combined,
when
possible,
by the printer into one print
operation.
For guaranteed
scan
accumulation, the following conditions must
be satisfied:
•
Line spacing set
to
8/240 inch.
•
Consecutive graphics ESC
Z
commands must be separated by
one
CR
and one LF
command.
•
Each ESC Z command must begin at the left margin.
•
The number of bit image data bytes represented by each
ESC
Z command
must be
the
same.
•
The print line length represented by the bit image data bytes
must
not
exceed the
right
margin or 13.2 inches.
•
Each ESC
L
command must
not
be separated by more than
one second.
