Labview e Network Analyzer HP3577A

Hi, I want to dump the spectra taken by a Network Analyzer HP3577A into a PC using a GPIB interface. I'd like to do it with labview. I found some labview drivers on the web but no one works. I have been working on this problem for days but I do not manage to find any satisfactory solution. I'm wondering if someone has already faced this problem and resolved.

"The HP3577A can provide a hardcopy of the CRT screen without a computer. It does this by direcctly controlling a digital plotter connected to the HP3577A's HP-IB port located on the rear panel. The plotter (such as the HP7475A) must accept Hewlett Packard Graphic Language (HP-GL) commands. The HP3577A must be configured in a Talk Only mode and the plotter must be configured as a Listen Only device. Refer to SPECIAL FUNCTIONS in the Reference Section."

If it's HP-GL instead of writing to a plotter, write to a text file.

Here are 2 Examples from the USER Manual which I OCR'd
