'Need an HPIB(GPIB) to Centronics convertor'

Okay, here's the story:
  There's a spectrum analyzer here were I work that I want to get
printouts from  (an HP8590E, circa 1990).  I guess when it was made,
a Centronics port wasn't standard like the HP8593L that I borrowed.
It will print to an HPIB port equipped printer, but I don't have one!

  So, has anyone worked on, know about, successfully coded a PIC
to convert from HPIB to centronics parallel port?  Any info is
appreciated.

Thanks
Dave

I know this is going to make the hobbyists cringe, but I believe
you can buy such a device for a couple hundred dollars.

Dave,
 You may try use next method, which not require PIC.It may be not
work absolutly propertly(in HPIL protocol), but in most case it
work right.Your HPIL device must be in 'trans. only' mode.
Of course, you may use PIC to connect device to computer.It is not
too hard, but i think that your work time is too expensive for it.
