There are five main components of an inkjet printer: print head, paper feeder, circuit board, power supply, and the case.
Nozzle plate: the part where ink goes through from ink cartridge to paper. Cover plate: covers the nozzles when they are not in use. Common ink chamber: where ink is transferred from the body before printing. (In piezoelectric printers) piezoelectric substrate: houses the piezoelectric crystal.
What is Deskjet? Deskjet printing is a type of printing where the ink is deposited on paper through a desktop printer. The most common type of deskjet printer uses thermal inkjet technology, which heats small drops of ink and sprays them onto the paper. Deskjet printers can only print on regular paper.
HP Spare Part means a new or refurbished part that has a HP part number and is obtained from a source approved by HP.
The key parts of the printer include, toner cartridges, image drum (also known as drum unit or photo-conductor), transfer roller or belt, fuser unit, laser, and mirrors.
A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard-size, 8.5″ by 11″ sheets of paper. Printers vary in size, speed, sophistication and cost.
Turn the product on while you press and hold the Resume button for 10-20 seconds. The Attention light turns on. Release the Resume button. The Attention and Ready lights cycle while the product restores factory defaults.
The two types of printer cartridges are ink and toner cartridges. Ink cartridges are used predominantly in inkjet printers whereas toner cartridges are used in laser printers.
Printers that use two cartridges (one black, one tri-color) can print if one cartridge is empty. To continue printing, remove the empty cartridge from the printer.
Another major advantage of laser printers is they print much faster and produce higher-quality prints than inkjet printers do. For example, the Xerox VersaLink B405, a laser printer, prints at speeds of up to 47 pages per minute (ppm), while the HP DeskJet 3755, an inkjet printer, only prints up to 8 ppm.
Side-by-Side Comparison

The HP DeskJet 3755/3772 and the HP OfficeJet 250 are both compact printers with sheetfed scanners, but the OfficeJet 250 performs slightly better for most uses. It has a higher page yield, a lower cost-per-print, and a rechargeable battery. Also, it can print directly from a USB thumb drive.

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.

Some of the features of Deskjets are: they are high-speed, may have wireless connectivity, lightweight, inexpensive, they have a disposable printhead which allows the print quality to be consistent as they can be replaced frequently as needed.

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.
