Qt based Common Print Dialog

To make printing easy for the users of desktop systems and mobile devices, we need a well-designed print dialog where one can easily find the right printer under the available printers, set general, printer-specific, and document-specific options, preview the printout, and send the job. But we also need consistency between applications i.e. printing should work the same way from every application, hence the plan to build a common print dialog that ships with the desktop environment itself and the dialog is called whenever one tries to print from any application on desktop or mobile system.
