Bytes per scan
The SCANWDTH function adjusts the scan width of the plot, defined
in bytes per line. The default scan width is
b1 (216 bytes per scan).
Menu settings are: b1, b2, g1, g2, g3, and g4.
b1 — 216 bytes/scan (bimodal).
b2 — 264 bytes/scan (bimodal).
g1 — 8 gray levels per scan, 1728 bytes/scan maximum.
g2 — 16 gray levels per scan, 1728 bytes/scan maximum.
g3 — 32 gray levels per scan, 1728 bytes/scan maximum.
g4 — 64 gray levels per scan, 1728 bytes/scan maximum.
Unless you are using RLTER (remote line terminate) commands, the
plotter scan width must be set to the same byte count as the rastered
data from the host. Setting the scan width higher than the byte
count of the raster data does not create a wider plot. Setting the
scan width incorrectly results in skewed output as the data “wraps”
and finishes the scan on the next line. This condition is identifiable
on the plot in Figure 7-8.
The V8.5e contains a new method of plotting raster data. Each
scan of data plotted can contain as many as 64 independent
intensity levels (gray scales). The thermal print head (TPH) in the
V8.5e is made up of 1728 thermal heater nibs, and each one of
these nibs can be heated to a different energy level, producing a
dot on the thermal media of varying intensity. This type of plot-
ting can produce high-resolution images containing many shades
of gray.
Change the scan width settings by pressing the up or down arrows
in the bytes/scan sub-menu.
