I was wondering if inkjet printers "know" if some of the print nozzles aren't working and if so do they compensation for it, within reason?

I have a Canon Pixma Pro 100s and change the printhead about once per year, once it becomes obvious it's past its best. I do regular nozzle checks and have noticed that there can be quite a bit of banding on the result but for day-to-day printing the quality is still good. It's only when a good number of the nozzles have failed that it becomes obvious outside of the nozzle check.

Does the printer know and compensation for lost nozzles?
