H
=
Horizontal resolution of the printer.
The possible selections are:
60 dots per inch (default)
72 dots per inch
120 dots per inch
144 dots per inch
If this parameter is omitted, the printer
will default to the last horizontal resolu-
tion selected.
B
=
Bytes of information to be received
by the printer. This parameter can be
set between 0 and 1900 for 13.2 inches
at 144 dots per inch. If omitted, the
value is O. When the value is 0, the
sequence is processed, but no raster-
graphics data is actually printed.
•
v
=
Variable line spacing parameter .
The value of V is the number of 1/144
inches to feed the paper. Values of this
parameter from 0 to 255 are valid. A
value of 0 indicates that a line feed is
not to be performed. This line feed has
no relation to the executable LF control
character.
The line feed spacing for graphics data
can be specified to a number of half
dot steps. When line spacing is not
specified, the normal line spacing is
used at the end of the line. An escape
sequence is not needed to return to 6
or 8 Ipi. Margins are ignored, and form
length is not changed during graphics
printing.
Example:
Set the printer to receive 300 bytes of graphics data, and print it at 60 DPI (dots per inch)
using a TI 850/855 - style sequence.
