Article in English: Adobe makes a free reader program that can be downloaded from their website. You can also download readers from a variety of other developers. If you'd rather not download a reader program, most browsers can open PDF files in a browser window. Use your reader program to open the PDF, or open it in your browser by dragging the file into the browser window. This will open a print dialog box displaying various options. Certain readers and web browsers make a Print button available at the top or bottom of the document without having to open the File menu. In the Print dialog box, you will be able to choose the printer that you want to send the document to. This is especially important if you are in an environment with more than one printer.  Check that the printer you selected is either directly connected to the computer or the network you are using and is working perfectly. A sufficient amount of paper should also be loaded in the printer. If your PDF file is multiple pages and you only need specific ones, use the Range or Pages section of the Print window to set which pages should be sent to the printer. Choose advanced printing features by clicking on "Properties" button. From here a number of selections can be made to the layout, finish, and other features of the PDF file. Additionally, this is where to select whether to print in color or in black and white.  The location of features will vary depending on the software you are using to open the PDF file. In Adobe Reader, a front cover as well as a back cover can be printed from the "Cover Mode" tab. In addition, in order to save printer toner "Toner Save" can be selected under "Quality". This will slightly reduce the quality of the final printed file. An additional way to save paper is to print double-sided by selecting "Two-Sided" under Print Type from the "Layout" tab. Once you have set all of your printing options, you can send it to printer by clicking the Print button. Your document will be added to the printer queue.
