My hp wireless printer and scanner is no longer working

Nice to meet you, *****!

What is the model of your printer?

This information is commonly found on the front, back, or bottom of the printer.
Okay ,thanks

Yes, thank you.

Please, try this:

1. Make sure your device is on the same wireless network as your printer.
2. Open HP Smart, and then select your printer, if it is not already selected.
3. Under Tools, click Print Quality Tools.
4. Next to Clean Printhead, click Clean or Clean Printheads.
5. After the printhead cleaning procedure, the printer prints a Print Quality Diagnostic report.
6. Examine the print quality on the Print Quality Diagnostic report.
7. If the print quality is acceptable, close the app and stop troubleshooting.
   If the print quality is unacceptable, click Second Level Cleaning or Level 2 Cleaning in the app to perform the next level of cleaning.
   If print quality is still unacceptable, wait 30 minutes and repeat this cleaning cycle.

Okay, great

Please, also check this:

1. Open HP Smart, and then select your printer, if it is not already selected.
2. Estimated ink levels display next to your printer.
   If none of the ink cartridges are low on ink, you do not need to replace them yet. Skip to Print a Print Quality Diagnostic report.
   If any of the ink cartridges are low on ink, go to Replacing Ink Cartridges for steps to replace any critically low or empty ink cartridges, and then try to print again.

Okay :)

Okay, seems you need to change cartridges if black is low.

Yes, exactly.
We are available 24/7, you can refer your questions anytime.

Depends on the level that was shown. You said that the level is low, so I recommended that you replace the cartridge.
Okay, I think 1/2 should be enough.

Okay, I understand.

Check for ink smears on the back of printouts:

1. If there are smears of ink on the back of your printouts, use an automated tool in the HP Smart app to resolve the issue.
2. Make sure your device is on the same wireless network as your printer.
3. Open HP Smart, and then select your printer, if it is not already selected.
4. Under Advanced, click Advanced Settings.
5. Click Print Quality Toolbox, or, under Tools, click Utilities, and then tap Print Quality Toolbox.
6. Click Clean next to Clean Smear.
7. A Rib Smear cleaning in progress message displays, and the printer ejects a blank page.

After cleaning ink smears, send a print job.

Okay, thanks
And this:

1. Make sure your device is on the same wireless network as your printer.
2. Open HP Smart, and then select your printer, if it is not already selected.
3. Under Tools, click Printer Reports.
4. Next to Print Quality Report, click Print.
5. A Print Quality Diagnostic report prints.

None of the colors at all?

Yes, let's try it again :)

Let's start with this:

1. Turn on the printer.
2. Load plain white paper into the input tray.
3. Lift the ink cartridge access door by using the recessed areas on the sides of the printer until it locks into place.
4. The carriage moves slightly to the left.
5. Wait until the carriage is idle and silent before you continue.
6. Lift the lid on the ink cartridge slot, and then pull up on the ink cartridge to remove it from the slot.
7. Remove the new ink cartridge from its package. Be careful to only touch the black plastic on the ink cartridge.
8. Remove the plastic tape from the ink cartridge using the pull tab.
