This test case describes the scenario of printing a document with the "duplex" setting enabled, i.e. printing on both sides of the paper.

Don't have a duplex-capable printer?
Try the NUp test case instead.

How to test

  1. Create a document using that is three pages long; make sure that the pages can be distinguished from one another by writing e.g. "Page 1", "Page 2", "Page 3" on them.
  2. Print two copies of the document, with double-sided printing enabled and with "collate" enabled (so that the printed pages can be easily separated into copies)
  3. Export the document as PDF and open that file in Evince by double-clicking on it in the file manager.
  4. Print another two copies of the document, as before.
  5. Do the same from other applications, e.g. Firefox, gedit.

Expected Results

What does "collate" mean?
When printing several copies of a document, the easiest thing for a printer to do is print however many copies are required of each page in turn, i.e. 3 copies of page 1, followed by 3 copies of page 2, etc. Turning on the "collate" option tells it that we want the pages already arranged into separate documents i.e. page 1, page 2, to the end of the document; then starting again at page 1.
  • For each print-out there should be four sheets of paper in the output tray in this order:
    1. A sheet with page 1 on one side and page 2 on the other
    2. A sheet with page 3 on one side and black on the other
    3. Another sheet with page 1 on one side and page 2 on the other
    4. Another sheet with page 3 on one side and blank on the other
