HP LaserJet 600 M602 printer goes offline every night

I have a HP LaserJet 600 M602 CE991A printer on a wired network. I have quite a few other printers on the network as well and do not show me this kind of behavior.
But for some reason, this printer, from as soon as I bought it, goes offline every time from around 5.20-5.30pm to around 8.30pm. I have a ping tester running as I am trying to figure out what's going on and I got 100% drop every night for that time period.
I looked to see if there was a setting that puts this device to sleep or so but no, I cant find anything. I have tried with the energy setting sleep mode on or off, wake up events to trigger a wake up call to the printer but no luck.
Firmware Bundle Version3.2.5
Firmware Revision2302908_435019
Firmware Date Code20140529
I am out of options, in our other locations, we have sam printer but a CE993A models and they do not show this kind of behavior at all.
I am at a deadlock here.

Hi @Halan ,
I see by your post that you aren't able to print when the laptop isn't in the same area as the printer. I would like to help you out today.
What is the distance of the printer and the Laptop when the printer goes offline?
Try these steps to see if it will resolve the issue.
