You star tsp100 evo tsp143IIU is dead from normal wear and tear. Best step would be to look on craigslist or eBay and find a used/ working printer. I found a lot of 2 printers for $90 after shipping and tax.
(Craigslist printers need to be tested with a laptop on site & eBay money back guarantee protects me if one does not work and the buyer refuses to refund me.)
Thinking viably and buy used. If you feel green, buy new $169.99 or buy a ebay hong kong replacement board for $32.
