Agilent still has this instrument manual available online:

Warning, This link may get mangled.
A quick look through the manual shows that the 8567A can send screen shots
to an HP pen plotter.
There are several sites on the internet that have software to make a modern
PC look like an HP plotter.

http://www.printcapture.com/index.html (reasonable, GBP 55, US$97.00)
To use any of these solutions you will need a GPIB interface card or USB to
GPIB adaptor.
The cards can be found on ebay. Get only Agilent(HP) or National Instruments
cards. Others are available but finding the correct drivers that will work
with the above software for your version of Windows can range from painful
to impossible.
I have no experience with the USB to GPIB interface adaptors. My friends
tell me that they work OK.
Both Agilent and National Instruments provide free high level language
programming support libraries to create applications than can remotely
control instruments. They also offer expensive development tool suites like
LabView.
