I have an ancient Tag Heuer 502 that has stopped printing, I realize that this is an old unit, but is it repairable or would there be a use by other for it?
Last I heard the 50X series of timers were no longer being serviced.
You may be able to find and old one for sale for $100 and either steal the printer or just use the new one you have if its settings are compatible with how you are using it. Different models had different output baud, etc.
