I am adding some functionality to an application that prints to a USB connected OPOS receipt printer. The system runs xp.
I want to see the raw data that gets passed to the receipt printer as well as have the printer physically print.
Is there any way I can do that? I looked some port monitors such as Advanced USB Port Monitor but they only detect and monitor devices that are accessible by native Operating System and not OPOS devices.
Any ideas?
Download and install the "debug" version of the OPOS common controls, instead of the "runtime" version. They will emit trace information you're looking for. http://www.monroecs.com/oposccos_current.htm
Be careful not to deploy the debug version in your production environment, as you might violate some requirements for data security.
