Printer problems

[Motorad]

My HP Color Laser Jet Pro MFP M$77fnw is always showing the status offline.  Once it's back online it does print but it's constantly offline.

Connecting how? If using network, having the printer driver setup on a WSD port is a sure way to have issues with connections dropping. It is more reliable to manually configure a standard TCP/IP port for the driver. 

Also if using wireless here are some other suggestions:

Many HP printers are/were built with older generation 5Ghz chipsets which can prove problematic with current 5Ghz networking equipment. That said, there are a few ways to mitigate the issue.
1. check to see if your printer network settings allow you to turn off the 5Ghz communication. This would be under network settings.
2. Check the settings of your router. Many newer routers allow you to restrict device connections to 2.4Ghz, which will stop the device from trying to communicate on the incompatible 5Ghz band.
3. If your router does not offer restrictions, the other method to limit the printer to only connecting to the 2.4Ghz channel is to configure the 2.4Ghz channel of the router to a unique SSID. (often the default from factory has both 5Ghz and 2.4Ghz using the same SSID). Then only configure the printer to connect to the SSID associated with the 2.4Ghz channel. As the steps are different depending on vendor it is impossible to layout all the steps for every product here. The supplier of your wireless should be able to assist.
