Printer Going Offline

I am working in junior system admin position and still going trough learning curve. I am finding that network printer in the office is going offline every few days.  When i log into server and look at the printer managers I see all other printers have ready status but printer in questions have either offline/not ready. At this point I usually find bunch of jobs stuck in the queue which I clear but even after that printer is still offline. I would then try to re-start print spooler few times and sometimes even whole OS reboot. Sometimes after this printer would come back online and at this point even it is not back online and I would go directly to printer and to reboot on it.

I guess what my question is if this troubleshooting routine is good and if there are any other steps I can take to quicker resolve this. Also where would I find exactly why this is happening. I am thinking maybe in event log but where within even log?

Any info from the community would be much appreciated
