element in the menu, then use the control knobs or keypad pop up menu to
adjust the setting. To restore the color map to its factory default settings,
touch the Default Color Map selector.
The color selections are expressed in terms appropriate to the selected
printer. When DeskJet Clr is selected, the colors are expressed as hexade
cimal RGB values. HPGL supports pen numbers 0 to 8.
Screen Format
The Screen Format selector provides several qualities of hardcopy output.
Different format selections are available for different printer types.
H HiRes produces an enhanced contrast display on printers with limited
gray scale capability (not availble for HP 560C). Selected items, includ
ing windows, are highlighted for easy identification.
H Draft produces hardcopies faster than HiRes mode, but sacrifices some
gray scale capability.
H Reduced produces low resolution hardcopies a quarter of the size of
Draft hardcopies. Advantages are quicker printing and use of less
memory.
H Screen produces an exact color replica of the screen without reformat
ting to enhance features. Available for color printers and plotters only.
H Dithered reduces saturation and increases contrast by dithering icons
and selector backgrounds. Dithered can be used with DeskJet Clr and
Bitmap Dump.
Direction
The Direction selector controls whether information is sent to a printer as
horizontal rows or as vertical columns. For most printers, this has the effect
of rotating the image by 90_. Some printers will produce an image more
quickly in one direction than in the other. When Direction is set to Horizon
tal, screen information is sent to the printer by horizontal rows starting at the
top left corner of the display. When it is set to Vertical, the information is
sent by vertical columns starting at the bottom left corner of the display.
Data Format
When Bitmap Dump is selected, the screen data is transferred as an ASCII
title block followed by a pixel data block. The format of the pixel data is
determined by the Data Format setting. Touch this selector to cycle through
the six available formats.
H TIFF sends a TIFF image. This format conforms to Rev. 6.0 of the TIFF
specification. Screen and Dithered screen formats generate Palette
Color (Class P) prints; Hires, Draft, and Reduced formats create Bilevel
(Class B) prints.
