Using PDF files as attachments (Microsoft Fax)

Adobe Portable Document Format (PDF) is one of the most popular formats when working with faxes. Therefore, we have to consider this topic separately. When using Mail to Fax feature, two different methods can be used, when preparing the fax from the original PDF document:

• Direct Converting to Fax of your PDF document (recommended)
• Printing the original PDF document (printto function) using standard Fax printer included in Windows Fax Service.

To use Direct Converting to Fax (recommended)

1.     Open Fax Voip T.38 Modem Control Panel.

2.     Click Fax in TreeView, then click Fax Converter.

3.     In the Select file types to be converted to fax format directly list, select the check box next to the Adobe PDF file type, to use direct converting for PDF files.

4.     Click <Apply> button. Do not forget to restart Fax Voip T.38 Modem to operate with new settings. To do this click <STOP> button, then click <START> button.

To print PDF files using printto

If Direct Converting to Fax is disabled for PDF files, Fax Voip T.38 Modem automatically prints PDF file using the standard program specified on your system for viewing and printing PDF files. Usually it is Adobe Acrobat Reader. Since version 8 of the Adobe Reader it has changed behavior when used to print PDF documents automatically. It will no longer close itself after being called using ShellExecute(printto, ...) API function. In this situation, PDF files can not be used as e-mail attachments.

Nevertheless, there is a solution to this issue. More information can be found at https://www.biopdf.com/:

You need to download and install Acrobat Wrapper. In this case the Adobe Reader will be closed correctly after “printing”.

If you use Adobe Reader with Mail to Fax function for processing mails with PDF attachments, the following should be taken into account:

• To automatically close PDF files after printing, the last version of Acrobat Wrapper should be installed after the installation of Adobe Reader.
• After any updates of Adobe Reader you must to reinstall Acrobat Wrapper. In this regard, it is desirable to disable the automatic update of Adobe Reader.
• The described method usually does not work in the case of configuring Mail to Fax as Windows Service regardless of the version of Adobe Reader and Acrobat Wrapper.

To download and install Adobe Reader do the following:

1.     Go to this web page at adobe site: Download new and previous versions of Adobe Reader .

2.     Select the operation system and the language. In the Select a version field select Reader 11.0.XX English for Windows or Reader DC 202X.X.X English for Windows. We recommend you to uncheck McAfee and Chrome Extension options, not clear if you need them.

3.     Click Download now button and follow the installation instructions.
