Microsoft: Bulk Documents Printing / Printing Multiple Documents at Once

You may print multiple documents at once by following the steps below:

1. Go to Start > Devices and Printers
2. Double click on the specific printer and a print queue window will prompt out ( Figure 1 )
3. Drag and drop the documents that you would like to print into the print queue window
4. Click OK to confirm the printing of multiple files at once ( Figure 2 )

Note:
Personally, the file formats that I have tested for this bulk printing are PDF, MS Word, MS PowerPoint and MS Excel.
