Hard Copy File Compression. When compression is set to on, the
oscilloscope compresses the hard copy data, using the current printer
format, into a gnuzip file format, with the extension .gz. Compres-
sing hard copy files lets you store more screen captures on a floppy
disk. Centronics output is never compressed. .gz files can be
decompressed using PKZIP or WinZip programs.
Color and Gray-Scale Printing. You can print a color hard copy that uses
the display colors. Gray-scale waveform information is printed as
shades of color. If you have a Deskjet or Laserjet monochrome
printer, gray-scale waveform information is printed as a dithered
image.
Ink Saver and Preview. As an alternative to printing the display colors,
turn on the Ink Saver function to print a hard copy with a white
background. This function saves printer ink while it preserves the
color coding of the waveforms and readouts. Ink saver also works
with the monochrome print formats.
Push and hold the Preview screen button to show how the colors will
appear on the paper.
Clear Spool. You can push the Clear Spool screen button to empty the
print spooler to stop a hard copy operation in progress, if the hard
copy port connection is not made due to incompatible settings (such
as baud rate), or if you lose the hard copy port connection before the
hard copy is complete.
