Hello Bicurico.
Have you a final conclusion about this? I have the exact same needs.
I want to "print" the screen of my TDS 210 (Tektronix Ocsilloscope) on computer (create a file on) via RS-232 or via Parallel port.
I know that someone will tell me to use the Tektronix download tool... but NO WAY. Proposed Tektronix software are sooo bad.
My TDS 210 Format options:
DPU411, DPU412,ThinkJet, DeskJet, LaserJet, Epson, BMP, PCX, EPSIMAGE, INTERLEAF.
Best regards,
