A typical ink cartridge will yield 250 to 300 pages depending on the color density of the prints. The yield of a typical toner cartridge in a laser printer is between 2,500 and 3,000 pages. Some larger laser printers can even have toners that will yield up to 30,000 pages!
Inkjet printers work via subtractive color mixing. As different colors of ink are combined, each ink absorbs (subtracts) its characteristic colors and amounts of light. The light that is then reflected back to our eyes is what we see as different colors.
From the File menu, select the Print option. Select the printer from the Printer menu. Expand the drop-down list, and then select Color Options.
Laser printers use microscopic ink particles in a powdered form known as toner. Once heated by the fuser unit, the toner melts allowing it to be fused to the paper fibres under pressure. Like inkjet cartridges, toner is most commonly used in the CMYK colours. Combined, these colours can recreate any colour palette.

A printer your business can depend on

If you want professional quality prints, an HP LaserJet Pro Color Printer can be the solution to your needs.

HP LaserJet printers use a laser beam and one (or more) toner cartridge to print directly without ink. Using laser toner cartridges, the typical laser printer can produce precision prints more quickly than ink. Unlike a laser printer, inkjet printing relies on liquid ink cartridges.

How Many Pages per Ink Cartridge On Average You Can Print? How many pages can you print with one ink cartridge? According to PCMag, a standard ink cartridge will print an average of 220 pages, (with 11 ml of ink). A high capacity cartridge prints an average of 350 pages, (its tank holds 16 ml of ink).
Printing on 10% = 240 pages. Printing on 20% = 120 pages. Printing on 40% = 60 pages. Printing on 80% = 30 pages.
How long do printer ink cartridges or toner last? If your wondering how long ink cartridges or toner lasts before they expire or ink dries up, ink cartridges are manufactured with a 2-year expiry date. When you get close to two years, the ink sponge inside the cartridge can start to dry up.
With HP toner, you`ll be using high quality cartridges that give you memorable results and make an impact in any business or home office. The ability to print around 1,500 pages means that investing in an HP 83A toner cartridge will more than pay off through high quality prints that last.
Four Cartridges

Just like color laser printers, some inkjet printers have four inkjet cartridges that hold cyan, magenta, yellow and black ink.

The “four-color” in “four-color printing” refers to the four ink colors—cyan, magenta, yellow, and black (CMYK)—used in offset printing presses and many digital presses. These four colors are combined to make a wide range of colors.
HP EasyColor scans documents and automatically adjusts photographic images in . JPEG or . PNG format. Rather than dividing an image into several pieces, HP EasyColor technology enhances the entire image at one time, which results in improved color consistency, sharper details, and faster printing.
Monitors display colors by light pixels using an RGB (red, green, blue) color process, but printers print colors using a CMYK (cyan, magenta, yellow, and black) process.
Color printing uses yellow, magenta, and cyan inks to produce various colors by subtractive mixing to give red, blue, and green. (Each color ink should be thought of as transmitting two of the additive primaries, which is the same as absorbing one of the additive primaries.)
Laser Printers work with CMYK toners only. inkjet printers and ink printers used for professional photo printing, for example, can use additional colors to achieve better printer results. Among other things, brighter gradations of magenta, cyan and also gray are used.
Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK). While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors.
While ink is standard in most conventional inkjet home printers, laser printers depend on toner and lasers for their output.
Laser printers, unlike inkjet printers, do not use ink cartridges. Instead laser printers use toner cartridges, so be sure to purchase accordingly depending on your printer.
While ink is standard in most conventional inkjet home printers, laser printers depend on toner and lasers for their output. Given that they`re based on their own unique technology, you`ll find that they also have their own unique advantages and disadvantages.
