My printer is offline and Im receiving an OFFLINE message regarding my H-P Color Laser Jet Pro MFP M477fnw

Not much of anything. Merely received a message from my printer supply status that "A non-HP supply has been installed." I have used non H-P cartridges for years. Print outs made today looked like I was low on ink - poor quality prints, so tried going into the small 2" x 4" window on my printer to make adjustments. Must have pushed too many wrong choices and am now dead in the water.

Yes. No luck.

Don't know what I need to do to "reset."

Did that, printer now Initializing . . . . now have the usual messages on the small printer screen, "Copy, Scan, Jobs, Fax, USB, Supplies, Apps and Setup. Would prefer to have you on "Hold" while I try to print something. Is this possible?

Okay. Put you into my "tray" while I test printed something . . . . No luck. Still offline. Message when clicking on Print states: "two messages waiting in que."

By merely pushing the on/off button? Or go through the process above one more time?

Okay. Printer shutting down. Will wait a few more seconds then turn "on." Turned on. Waiting for printer to reach "Ready". Now putting you back into my tray and will attempt to print.
No luck. Earlier, I was looking in Windows at printer selected and the correct printer is selected from choices shown. Any other ideas?????

No. Where would the error codes appear. I was in WORD attempting to print.

Zero. Notha.

How about disconnecting the printer from the power source and treating all this as new printer just out of the box and setting it up for the first time?????

So, you want me to try the on/off "Permanent Storage Init" as before????????

Okay. Scrolling back up to your instructions. Do not leave the building . . . THIS TIME, followed your instructions EXACTLY and put my third finger on the "Home" icon. Never did receive the, "Permanent Storage Init". Now going to try and print again. Hold on.
No luck. Took a look at Windows Devices and Printers to verify correct printer is selected. I have the correct printer selected; Color Laser Jet Pro MFP M 477fnw.

No, still using same cartridges I've always used. Have been holding off spending $560. for four new H-P cartridges. Is a cartridge change going to be my only alternative? Can you guarantee the $560. will solve my problem?
Will System Setup on my printer be an area to look into? Choices are: Volume Settings, Time/Date, Inactivity Timer/Energy Settings, Supply Settings, and such like.

Wireless.
Just noticed a wireless icon at top RH side of printer screen. I hit "Reset" at top LH side of screen. Going to try printing again.

You mean an H-P cartridge? Answer = no. Printer has worked just fine with my non H-P cartridges, but it appeared that I might need some replacement no H-P cartridges as the colors on one side of the print out were leaning toward pink. Removed cartridges, gave them a good shake, cleaned then as best I could from the outside. Don't think this is a cartridge problem however as much as a pure and simple printer on line off line problem.

NO, printer will not print. I just ran a "Wireless Network Test Report." It indicates what we already know, "Wireless On/Fail." Also, "The wireless radio on your HP printer is currently turned OFF. To connect wirelessly, you must turn ON the wireless radio on your HP printer. Refer to the wireless menu.

just figured out how to reconnect to Wireless. Message on printer screen is now, "Connection established, SSID: Houseman1, Channel: 6." I now have printed the rest letters successfully that were waiting in the que. Hold on a moment please. Now printing successfully! I went into "HP Web Services and followed the directions for getting on line. Voila! Looks like all is well. Sorry for taking all your time this afternoon. You can now leave the building as far as I'm concerned. I am more than happy to pay one dollar for your services.
