Why can't I connect to the printer even though I installed TSC?

Installed TSC can not connect to the printer, usually the computer can not connect to the printer:

1, check whether the printer cable is normal, the two sides of the port is not a problem, this is a data cable problem.

2, check whether the printer driver added to the computer is correct, you can see whether the selected port is a problem, this is a computer problem.

3, check whether the printer port is normal, you can re-replace the interface will find the hardware, this is a machine problem.
