Hi, we have a vb.net 2008 application running on a Motorola CE device and want to be able to copy a file with Zebra ZPL commands to a Bluetooth connected printer setup on Com4 port. I have it working where it can loop through ans write one line at time but would like to see if we can just copy a file to the com port. I have done in DOS where copy to printer ports but not sure if possible in VB to com port. Thanks, Joe
