Tool to Convert ODT to PDF Using Virtual Printer Downloads
ODT is the file extension used by the OpenOffice suite and file format to store text documents. PDF is a file format to represent computer-made documents that are independent from the operating systems and apps.
A virtual printer is an app that has its API and user interface similar to those of a printer driver but it's not connected to an actual, external, physical printer.
The apps from this set will install themselves as virtual printer and can convert ODT files into PDF ones using their virtual printing functions.
