Microsoft has recently rolled out some updates that have fixed a bunch of problems – and issues related to fax modems in Windows have also been taken care of.
The issue ‘you cannot print fax by using a fax modem in Windows’ has been recently address by Microsoft and fixed with a hotfix that is available for download. Here’s how the error has been described:
When you send a fax job by using a fax modem that is installed in or connected to a computer that is running Windows 8.1, Windows Server 2012 R2, Windows 8, or Windows Server 2012, the fax is not in the Windows Fax and Scan outbox. Therefore, the fax is not printed.
Microsoft says that this issue occurs because calling of the FaxStartPrintJob function works incorrectly. Follow this link to download the hotfix or make sure that you have the latest update roll out delivered via Windows Update.
