When a job leaves the queue without a page, check the selected printer and the device's own status. A disappearing job alone does not prove that the document printed.
Find the destination
In the application's print dialog, confirm the exact printer rather than Print to PDF, a duplicate queue or an old shared printer. Then print a Windows test page. If it goes to a different device, correct the destination first.
Check printer versus application
Print a built-in printer page. If it works, try a simple document from another app. If Windows' test page also disappears, inspect the port, network address, current on-device error and the manufacturer's support guidance.
