In 1988, HP introduced the first DeskJet. It included a built-in cut sheet feeder, 2 ppm, and 300 dpi. This was followed by the DeskJet Plus in 1989. It offered a landscape printing ability.
The power consumption of an average inkjet printer is 30 to 50 watts in printing mode and around 3 to 5 watts while on standby mode.
From anywhere, to anywhere. It`s not just the HP DeskJet printer itself that`s versatile. With optional WiFi and smartphone connectivity, you can scan from wherever you are, right to your smartphone or tablet, and send to the printer.
If you look at the back door cover of the printer there is a label that has your model number serial number and also includes the date of manufactuer. Hope this helps.

A no-brainer

More affordable than ever, compact, and boasting new features and connectivity, the HP DeskJet is the right printer for all your in-home needs. Plus, you can save on an HP DeskJet when you buy one with a new HP PC.

Method 1 – Basic Troubleshooting

Check the connection status between your printer and your PC. Ensure the printer, the PC, and the network or cable are correctly connected. Restart your HP printer. Power it off and unplug the power cord.

What`s the average lifespan of a printer? The average lifespan of a printer is around 3-5 years. With proper upkeep and maintenance, some printers can last longer, but eventually your machine will need an upgrade.
Ink cartridges can usually last two or three years if properly packaged and stored. But in a standard case, they will eventually dry out and become useless after this period. However, many major ink cartridge makers don`t put expiration dates on their cartridges.
For healthier print heads and more efficient ink consumption, however, it`s better to leave your printer on. Constantly switching your printer off and on will decrease your printer`s lifespan, so try to keep the off/on to a minimum.
The printer supports one active local (USB) connection and one active network connection (Ethernet or wireless) at a time. It is not possible to connect the printer to both Ethernet and wireless networks at the same time.
In Windows, search for and open Add a printer or scanner . Click Add a printer or scanner, and then wait for Windows to locate available printers. If your printer is found, click it, and then click Add device to complete the driver installation.
Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer`s USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.
Some HP printers have a built-in Bluetooth radio that supports pairing with a computer, mobile phone, or tablet to enable wireless printing. Turn on the Bluetooth radio on the printer. Depending on the model, press the Bluetooth button , or navigate to the Setup or Network menu to access Bluetooth settings.
Most modern models have wi-fi built-in, but if yours doesn`t, there are still ways of making it work wirelessly by connecting it to a router. But before you can start printing, you must first connect the printer to your home network – all you`ll need is a wireless router and a wi-fi printer.
Restart devices

If your printer connects to a Wi-Fi network, disconnect your computer or mobile device from the network name (SSID), and then reconnect it to the same network name your printer is connected to. If the printer is available and has a ready status, the issue is resolved.

Make sure the printer is near the Wi-Fi router, paper is loaded in the main tray, and that it is turned on. On your Windows computer, open Printers & Scanners and delete the printer. Open the HP Smart app, and sign in. If you do not have HP Smart, download it from 123.hp.com or your app store, and create an HP account.
Simply plug the USB cable from your printer into an available USB port on your PC, and turn the printer on. On the taskbar, select the Search icon, type Printers in the search bar, and then select Printers & scanners from the search results to open the Printers & scanners system setting.

HP deskjet 460 Waste ink tank full
ANSWER : I worked fixing printers for 5 years for Verizon and some of the older printers were notorious for the waste receptacle filling and overflowing with ink. My solution was good old warm water. Remove the waste container and scoop out as much as you can with a small screwdriver, wiping the discard on a paper towel, then just run warm water from the faucet into the container till all the residue is removed. This is just water soluble ink folks, if you want to test it, scoop out a glob and dissolve it in warm water, its easy as pie. I never once bought a new ink discard reservoir. I just cleaned out my mobile 460 printer reservoir by the same method. There are no electrical connections its just all plastic.
