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).

Menusettingsare: 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.
