Hi there, My project is developing firmware for USB based printer interface which replaces the printer's parallel port interface card.
Iam using Cypress CY7C68013a controller for this purpose. The printer contains a master board to which our card will be interfaced and it must be programmed in EPP mode.
Iam not able to understand as to how the busy signal is to be polled in the EPP mode. Kindly give me your suggestions.
