Rodolfo, One of the guys here that works with Intermec printers suggests the following: Set up the port as a terminal Build in a timer to your application (using WAIT or PAUSE) Unfortunately, this is a trial and error situation. He says the printer won't handshake properly with the 3000. Good luck! Don I know the thoughts expressed here are my own because no one else would claim them!
