The standard printto verbs are used by Windows to associate file extension with application responsible for printing of files with given extension. For example, to print text document (*.txt) notepad.exe application usually used. To print files with .doc and .rtf extentions Microsoft Word is used. Printing PDF is usually associated with Acrobat Reader etc... To print files in different graphics formats shimgvw.dll system library or Paint application typically used.

Fax Voip Softphone uses printto functionality in the following cases (except when using the Direct Converting):

• To Send a Fax from the Fax Panel (printing to Fax Soft Virtual Printer).
• When you print a fax in the Log Book (printing to printer selected by user).

The described printto functionality is very useful, but it depends on the applications installed on the system and the settings made ​​by the user. Lack of correct file associations leads to inoperability of the above functions with certain file extensions. Even in the case of well-known extensions, the file association can be corrupted when you install new application. Starting with Windows Vista not possible to configure printto file associations via user interface. In Windows 11, Windows 10 and Windows 8 / 8.1 the default associations do not allow the use printto with most of file extensions. In Windows Server OS this problem is not present because new Windows Store apps is not installed by default.

The function described in this chapter restores correct file associations for standard file types.

Note, that in Windows 11 and Windows 10 the function described in this chapter not always resolves all the issues and the file associations should be assigned manually, see To manually fix file associations in Windows 11 and Windows 10 chapter of this user manual.
