I don't believe there is anything built into Qt to print the contents of an existing PDF file. Poppler (http://people.freedesktop.org/~aacid/docs/qt5/) is a popular GPL library that can be used to accomplish this.

Hi, I think , it will depend on the printer you have. However, I also found out that it is possible to print pdf file on usb printer through qt. You may checked this: Printing With Qt (http://doc.qt.io/qt-4.8/printing.html) . That might help you.
