Normal Density Plot
:
D
The mode is selected with the odd dot plot control code ENQ (05 hex).
DThe
odd-numbered dot columns are addressed to produce a horizontal and
vertical
density
that varies, based on the mode of operation:

Different print modes cannot be mixed on the same dot row.

Double Density Plot:
DTwo separate shuttle strokes produce double density plot. First the even plot comĆ
mand
(EOT
, 04 hex) and
dot data are sent, followed by the odd plot command (ENQ,
05
hex) and dot data, allowing a maximum of 1584 dots in a single dot row at 60 dpi.
DEven dot plot is sent first for control of the initial plot pattern; then odd dot plot is
sent
for control of the final dot pattern.
D
The dots average .017" in diameter.
D
The vertical density remains the same in normal and high density plotting.
