How to password protect batch print

[Skeptical]

We have a Canon imageRUNNER C5068 in our office. We are around 20 people working and our computers are connected to this printer. Sometimes we all needed to take bulk (200 or more Sheets) printouts from TEKLA STRUCTURE Software. How we can password protect these batch print and take prints (now we announce to everybody in the office tht “I am going to print  for an hour pls don’t disturb”. This is very annoying to all. Pls help.

I don't think you can do it without the proper software.... Correct me if I'm wrong.
Ashampoo Magical Security is a good security program. It can password protect any kind of file/program.

It only costs $20, so I think it's worth it.
