Abstract

This thesis explores the modification of an EPSON EcoTank ET-8500 desktop inkjet printer to facilitate printing on CMOS chips for the cost-effective production of capacitive sensors. By reengineering both the hardware and software of the ET-8500, we aim to repurpose this standard desktop printer into a tool capable of advanced, precision printing for electronic applications.

The report details the development process, beginning with an overview of printer drivers and the Epson Standard Code for Printers (ESC/P) language. Utilising this foundation, custom software was developed in Python, featuring a user-friendly interface for seamless operation. The customised system was rigorously tested to assess the modified printer's capabilities, with results thoroughly analysed to determine feasibility and performance. The thesis concludes with a discussion of findings, along with recommendations for future enhancements and applications.
