TCP/IP communication with Markem9030 printer

Good afternoon, you guys, I have a program in c# that opens a socket connection using TCP/IP and writes some data... when reading the answers it receives a few bytes that when converting to HEX it looks like this:

FF FD 03 FF FB 03 FF FB 01

Does anyone know what it means?

In short, if everything was right the device on which I am connecting should return 06 in HEX.

I am trying to communicate with a Markem 9030 printer with network interface. It is already configured for TCP Socket communication...

Thank you,

tcpclient

  • http://www.rapidtables.com/convert/number/hex-to-ascii.htm gives ÿýÿûÿû

  • I had already converted this way too... but I have no idea what these characters mean... rs
