Hi everyone, I developed a management software for hotels in jsp and java and considering that from 1 january(in italy) the receipts must be elettronic I would have to interface the software with a recorder (in my case custom) using the xon / xoff protocol. my fiscal recorder uses the ethernet port so I should develop a procedure for printing the receipts. Considering that this is the first time that I have been developing this type of application with interfaces to external devices, I wanted to know if anyone could help me for the connection procedure with the cashier.
My first question is, should I install the device drivers or is it ethernet not needed?
Which libraries should I use?
There is someone that have developed some application?
