A hardcopy of a frame shown on the image display or stored on disk can be
made only if the site has appropriate devices
(see Appendix 
which gives the detailed
description of the available options).
Grayscale and colour hardcopies can be produced only on Laser printers
which support PostScript.
Typical command sequences for getting an image hardcopy are:
LOAD/IMAGE frame ! load image into image display
COPY/DISPLAY ! make hardcopy of screen
or
ASSIGN/DISPLAY device ! assign hardcopy device as display
LOAD/IMAGE frame ! load image to hardcopy
where available devices and special parameters are described in Appendix
. In addition, a set of device specific
commands are normally defined to set it up and to get status information (see
Appendix ).
