LaserJet as a brand name identifies the line of laser printers marketed by the American computer company Hewlett-Packard (HP). The HP LaserJet was the world`s first desktop laser printer. Canon supplies both mechanisms and cartridges for most HP laser printers; some larger A3 models use Samsung print engines.
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.
Ans. Laser printers are quicker than inkjet printers, generate higher-quality output, and are better suited for high-volume printing.
Engineered for high-volume printing – get 5,000 pages of toner right out of the box. Get print speeds up to 20 ppm.

Press the Win + S hotkeys to open Windows Search. In the search bar, type System Information and choose Open from the right pane. Choose System Summary from the left sidebar. Check the System Model row in the right pane to know about your computer model name.

Like a photocopier, laser printers read the electronic data from your computer and beam this information onto a drum inside the printer, which builds up a pattern of static electricity. This attracts a dry powder called toner onto the paper which is then fused using heated rollers.
HP, also known as Hewlett-Packard, is a home electronics brand that focuses on computer-related products, including printers. They make a diverse range of printers like inkjet or laser, color or monochrome, all-in-one or print-only units, and even portable printers with a built-in rechargeable battery.
Laser printers are more efficient, printing pages more quickly than comparable inkjet printers perform. The printing process is noticeably quieter with a laser printer vs. inkjet. Even when not in use for long periods of time, toner does not run the risk of drying up and becoming unusable.
While ink is standard in most conventional inkjet home printers, laser printers depend on toner and lasers for their output.
Quality: While inkjet printers are considered powerhouses when it comes to high-resolution color printing, laser printers do produce solid color and black and white results.
The main function of the printers is to present text or images to flat media such as paper in various sizes. After all, everyone needs a printer for different needs. For example, high school and college students usually need to print black and white documents.
The best print speed for everyday prints (medium quality) is about 50–60 mm/s. However, users should note that some materials can be printed very quickly (e.g. PLA) while some require a slower rate to prevent warping or print failure (e.g. TPU).
Laser printers are faster than inkjet printers too. Print speeds are denoted in pages-per-minute (PPM). Laser printers have print speeds of 14 PPM and higher. The basic laser printer can print about 30 to 40 pages per minute, whereas high-end models churn out more.
Improve Productivity

The powerful HP LaserJet P4015 Printer series features print speeds of up to 52 pages per minute (ppm), and the Instant-on Technology delivers a quick first page in less than 8.5 seconds from Sleep mode, so you can boost team productivity.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail.
