I don't understand Win32::SerialPort but I know serial printers.

What languages does the printer use (I'm guessing Barcode printer)? (proprietary, ESC/P2, ...) - If it's proprietary can you post what the stings are and what they're supposed to do?

Are you supposed to sending '~' as part of the printer language? Most languages use ESC (\e or \x1B) to begin a command string.

Sorry if I am missing something Win32::SerialPort does with ~ in the background.
