I have an Electronic Fiscal Device (EFD) Daisy PerfectS that i need to integrate with my web based application to be able to print sale receipts to customers. The fiscal device is set in such that it accepts commands through a virtual port that is created once connected. The aim is to be able to print receipts with correct format when ever i command print on my POS (Web Base Application).
Ideally, we need to convert the receipt print information from POS to a language & format that will be understood by the EFD printer.
Attached herewith is the PC to EFD protocol document.
