Workshop Project #22 - HP 2225A ThinkJet

And here we have an addition to the HP 1630 Logic Analyzer video; I quickly found out that it can print a hard copy of the data, but only via the included HP-IB port... And that's when I ventured to ebay again, to find myself a printer with an HP-IB port. I found a set of two "well used" ThinkJet 2225A printers. Thinking that between two non-functioning ones, I might be able to get one functioning out of the deal, I went for it...
