setpagedevice
/_PigmentSenseLevel
Integer or fixed-point. Controls the sensitivity of the sensor used on
some printers to detect the presence of the printing pigment. The actual
pigment used varies by printer technology. Pigment can include inked
ribbons, toner, thermal transfer ribbons, or other technologies. The
value specifies a percentage of the maximum sensitivity provided by the
sensor. A value of 100 implies absolute sensitivity. A value of 0 implies
no sensitivity. Absolute sensitivity will normally result in the printer
constantly believing that the printer contains suffient pigment to print a
page. No sensitivity will normally prevent the printer from detecting the
presence of the pigment. The proper setting will normally fall some-
where closer to the middle of the range, depending upon the operating
conditions. Not all printers support this parameter. This parameter is
ignored on the Fastmark series of printers.
/_PresentDistance
Integer or fixed point. This feature is only available on the Fastmark
series of printers. Allows the presentation distance to be set.
/_VertAlign Integer or fixed point. This feature is only available on the Fastmark
series of printers. Allows the printing to be shifted in the vertical
direction. This parameter is specified in inches and effectively sets the
Vert Align feature available through the front panel.
Comments
This operator performs extremely printer dependent configurations. The programmer should con-
sult each printer's documentation to determine the relationship of these parameters to the operation
of the printer.
PAL always performs initgraphics and erasepage operations while processing the
setpagedevice operator.
