iSys V8.5e Thermal Printer - Manual (Page 26)

This feature is enabled by setting the formfeed menu to “PF” The advance range is from
01 hex --- 10 scans (approx 0.05”)
to
ff hex --- 2550 scans (approx 12.5”) in increments of 10 scans for each hex number.
Once the menu has been set to “PF”, the amount of advance past TOF which has been programmed into the
V8.5e will be used until it is changed. The default value is 23 Hex.
To program the amount of advance past TOF, send header:
98 XY 0A (where XY is the hex# of groups of 10 scans).
If the V8.5e accepts the setup string, the display will flash
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 plotting 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.
