ZXPrinter Shield - Only $15 + shipping

Connects Arduino to Timex/Sinclair Printers
Open Source Project - software on GitHub

To be clear... this is a product for Arduino enthusiasts. 
It is not for Timex/Sinclair Computers... only for Timex/Sinclair Printers.

UNO R3
ABOVE EXAMPLE:  Arduino UNO with ZXPS is taking power from a USB cable, and a temperature and humidity sensor is hooked up to the ZXPS through it's optional Qwiic connector level shifiters.  

 

ZXPS top fully loaded a 1000wZXPS with basic printer components,
plus the optional Quiic/STEMMA and Serial interface components installed.

UNO R3
ABOVE: The ZXPS as shipped.  The 9 components needed to complete the printer function are large, easy-to-solder thru-hole components.  Typical assembly time is 10 minutes. 

If you are going to interface to a 3.3 or lower voltage I2C sensor, 8 SMDs are included for an optional Qwiic/STEMMA circuit, but this requires good eyesight and surface mount device soldering skills and tools.
