 ## Print document
 From version 1.9.0, myrtille does support local or network printing through a pdf virtual printer, "**Myrtille PDF**", installed on the gateway. This feature can be disabled into bin/Myrtille.Services.exe.config ("FreeRDPPdfPrinter" key).
-It works like any other printer, using the print feature of your application. The resulting pdf is then downloaded to the browser and can be opened/saved/printed from there.
-It can also work standalone (without myrtille integration). If used directly on the gateway, or through a network/redirection, it will ask for the pdf output location (to change that default behavior, see bin/Myrtille.Printer.exe.config).

 Alternatively, on Windows 10 / Server 2016, Windows provides a "Microsoft Print to PDF" printer. You can thus create a pdf on the remote server then download it (using the file transfer), but it implies an additional step.
