No one know? I have already add cent.

CodePudding user response:

Quite quite difficult, want to intercept the data through the printer port, it is too difficult, even if intercepted, you also are difficult to analyze the data inside

CodePudding user response:

Monitor the parallel PB can be difficult to achieve, can ask to VC section, a lot of this information

CodePudding user response:

Thank you, it's time to post.

CodePudding user response:

From the parallel data to transform through many layers, not easy to implement in practical application
Consider from other sources, such as the other program of data source (database \ keyboard), etc., it should be much easier.
