Hp 97 print head problems-missing row

[Jonas Sandstedt]

Hello,

Some alternative printhead sources are discussed on page 2 and page 3 of the thread "HP-19C Repair Odysee". Perhaps you can find some useful hints there?
Furthermore, I do not know of its printhead characterstics, but TI-5008 is an example of a relatively inexpensive calculator (on Ebay) with a small Epson thermal printer.

best regards
Jonas
