How to print a document with Universal Print from Web Application

[hungnq39]

Hello, I am currently developing web applications and Universal Print.
I have successfully performed 3 steps: create print job, upload Data and start Job on a printer that is registered Universal Print with PrinterConnector.
The printer has also met the conditions like Shared, ... but we do not see the job done on a physical printer.
Please ask what we need to do to print the document.
How does a physical printer receive print jobs of Universal print ?

@hungnq39, based on the steps in your web application, I'm assuming you are using the Graph API.  Was there any error in the startPrintJob call?

Separately, if you have access to https://portal.azure.com/#blade/Universal_Print/MainMenuBlade/Printers, I recommend checking on the print job status for the document.

Additionally, you can check the Event Viewer tool on the PC hosting the Connector to see whether or not the Connector reported an error while trying to retrieve the print job.  From a command prompt or the 'run' command, execute "eventvwr /c:Microsoft-Windows-PrintConnector/Operational".

HTH,

Jimmy
