So working on an SDK proof of concept console app with Asynchronous printing. I have the following code that I have grabbed from the SDK Examples for Asynchronous printing.
Code: Select all
// Print the specified number of labels and retrieve the PrintRequest interface.
this.printRequest = label.PrintAsync(1);
// Add handler for the PrintRequest's PrintJobStatusChanged event
this.printRequest.PrintJobStatusChanged += this.PrintRequest_PrintJobStatusChanged;
// Add handler for the PrintRequest's SpoolJobStatusChanged event
this.printRequest.SpoolJobStatusChanged += this.PrintRequest_SpoolJobStatusChanged;
I have created the events necessary but when I go to check the status, these events are never hit. The job status essentially stays at Created for the print job and Unknown for the Spooler status. I am unsure if this is a driver related issue or a code related issue. Any insight on troubleshooting this issue would helpful thanks.

Before we continue I would like to know whether the "SimpleAsyncPrintSample" project raises the two events if you run it.
I tried what you are suggesting here in the headquarters on a couple of computers and it seems to be working.
Let me know what happens with the "SimpleAsyncPrintSample"...
