If you make a copy and it only prints one side, the problem is the CIS. The CIS is the strip that lights up when the paper goes through the document feeder. If it is only lighting on on one side, this is your problem. It could also be a problem with the laser unit.
If you print an internal document, such as a report or help page and it is only printing on one side, then the problem is most likely your drum unit or toner. Good luck

Pint on the right side of the page only left side is blank

Hi, take the toner cartridge out and shake it left and right (horazontaly) not up or down or tipping it. Place back in unit and print one page. Does it now print on both edges? If so just replace the toner cartridge as you are running low. If that does not solve the issue contact me again.

The printer prints on right hand side while left hand side is blank

Reinstall the printer driver, for starters. failing that take the toner cartridge out, give it a gentle shake end-to-end so that the toner powder inside is fluffed up, and then put it back. You may need to change the cartridge completely. HP lasers are usually pretty good.

Hp 2820 prints only on right side of page

Yes, you will need to replace the drum unit as well. be sure to shop around so you can get the best price because some people mark up the price for that part. You can check the status of your supplies from the printer itself by pushing the "menu" button the printer and scrolling through until you see something about supplies status then press the check mark button.
