Monitoring While Idle

In order to get status any time a status thread has to be implemented which reads printer

status and provides changed status information in the same manner. The following code

snippet in C# may be used as a guide to develop such an application. The code is using

the KRConfig DLL.

KRConfig config = new KRConfig();

config.Load();//Load settings from registry

string msg = "";

try

{

config.open("LPT1:");

//getStatus is not synchronized with other read/write

functions

byte status = config.getStatus();

msg = "Status : " + status;

config.close("LPT1:");

}

catch (Exception ex)

{

msg = ex.Message;

MessageBox.Show("Status : " + msg);
