The oscilloscope can also output copies of its display using the hardcopy feature.
This feature allows you to output waveforms and other on-screen information to
a variety of graphic printers and plotters from the TDS front panel, providing
hard copies without requiring you to put the TDS into a system-controller
environment. You can make hardcopies in a variety of popular output formats,
such as PCX, TIFF, BMP, RLE, EPS, Interleaf, and EPS mono or color. You can
also save hardcopies in a disk file in any of the formats above. The hardcopies
obtained are based on what is displayed on-screen at the time hardcopy is
invoked. The hardcopies can be stamped with date and time and spooled to a
queue for printing at a later time. You can output screen information via GPIB,
RS-232C, or Centronics interfaces.

The TDS 684A and 7XXA Digitizing Oscilloscopes offer flexible display
options. You can customize the following attributes of your display:

H Color: Waveforms, readouts, graticule, and variable persistence with color

coding

H Intensity: waveforms, readouts, and graticule

H Style of waveform display(s): vectors or dots, intensified or nonintensified

samples, infinite persistence, and variable persistence with color coding

H Interpolation method: Sin(x)/x or Linear

H Display format: xy or yt with various graticule selections including NTSC

and PAL to be used with video trigger (option 05)

This oscilloscope also provides an easy way to focus in on those waveform
features you want to examine up close. By invoking zoom, you can magnify the
waveform using the vertical and horizontal controls to expand (or contract) and
position it for viewing.
