Connect to a Hardcopy Device. To connect the digitizing oscilloscope directly to a
hardcopy device, determine which interface and cable the device uses, and
connect accordingly. (See Figure 3–28.)

Print. To print a single hardcopy or send additional hardcopies to the digitizing
oscilloscope spool (queue) while waiting for earlier hardcopies to finish printing,
press HARDCOPY.
Abort. To stop and discard the hardcopy being sent, press HARDCOPY again
while the hardcopy in process message is still on screen.
Add to the Spool. To add additional hardcopies to the printer spool, press
HARDCOPY again after the hardcopy in process message is removed from
the screen.
You can add hardcopies to the spool until it is full. When the spool is filled by
adding a hardcopy, the message “Hardcopy in Process — Press HARDCOPY to
abort” remains displayed. When the printer empties enough of the spool to finish
adding the last hardcopy it does so and then removes the message.
Clear the Spool. To remove all hardcopies from the spool, press SHIFT
➞
HARDCOPY MENU
➞ Clear Spool (main) ➞ OK Confirm Clear

(side).
The oscilloscope takes advantage of unused RAM when spooling hardcopies.
The size of the spool is, therefore, variable. The number of hardcopies that can
be spooled depends on three variables:
The amount of unused RAM
The hardcopy format chosen
The complexity of the display
