I am using an old HP agilent 8591EM spectrum analyser. It has a parallel output to a HP deskjet printer but its getting hard to find printer cartrdiges.
I am wondering if its possible to output a screen shot to a PC using the parallel port. I have read some stuff online about the protocol HP uses for printing in deskjet -PCL3 and guessing the SA uses this same protocol. I am also thnking of making a DB 25 to DB 25 dongle for SA to PC. I guess I need to switch the pins on PC status port and control port as I will be sending out status commands thru PC.
Also I was wondering how much current the SA would supply across the parallel port to PC when i connect it.

Might be cheaper to use GPIB to pull the data over to a PC.
