If you are using an older version of a PDF reader (which happens a lot), then sometimes that PDF reader will have trouble communicating with your printer. You’ll know this is the case because some images will appear as black boxes, pages will print out blank, or pages will be divided up in a way that does not match what you are seeing on the computer screen.
Luckily, this is a problem that can be rectified in a few easy steps!
1. Download Adobe Reader (it’s free!).
2. Once Adobe Reader has downloaded, open it.
3. Open the worksheet file using the reader (go to File > Open).
4. Go to File > Print, and the result will be top-notch.
