# epson-l3110-driver: investigating the printer's USB and ESC/P-R exchanges

> epson-l3110-driver investigates the Epson L3110's USB printing exchanges while developing a Linux driver in C. Its notes use captured print-job traffic to identify the IEEE 1284 device ID, EJL session setup and ESC/P-R command framing. USB communication is still in progress, and the driver cannot yet print pages.
