mmm, could be, but can you confirm you already program a 16F628A with the same programmer before?
Assuming there's no faulty/dirty/loose connector pin (DIP & Printer ones), your printer cable is OK and you don't have any switch-box in between... it has to work.
Apart of a cold joint, those on-Board Transistors is my last bet. Even if they test good with a multimeter, they could be lazy and/or leaky... Lazy electrolytic? mmmpfff
Bah why not change all parts on, as there only a few?
Sure a weird coincidence with the HP printer... In the HP Printer Properties, is the printer assign to a DOT port? let's say DOT4_001? Is the Enable printer pooling check box checked?
