What Are The Best Laser Printers

Our favorite laser printer overall is the Brother MFC-L2750DW, a monochrome laser printer with all-in-one capabilities that’s built to handle all of the printing needs of a small office with speed and efficiency. In addition to fast printing and copying it has a speedy document feeder and extremely low cost per page.

Other favorites include the budget-friendly brother HL-L2390DW, which offers monochrome printing, scanning and copy capability, and sells for a very reasonable price.

For a slightly more expensive alternative, the HP LaserJet M234dwe is another great laser printer with lot’s of cloud-friendly features, like printing from mobile and easy online connectivity.

Build And Durability: Do Laser Printers Or Inkjets Last Longer

Again, ignoring the cheapest inkjets and monochrome lasers, the durability answer depends solely on the machine itself and how it’s used. I’ve seen some laser printers with flimsy pull-out trays and inadequately reinforced innards I’ve also seen inkjets, like most of Brother’s Business Smart and Business Smart Plus series, with heavy, metal-reinforced frames and other substantial parts.

Some machines on both sides of the aisle make excessive noise, indicative of poor insulation. You also want to beware of printers that shake and vibrate not only their chassis but also the table they’re sitting on.

Early laser printers were built like Sherman tanks and lasted forever you could keep a printer for a decade and your only reasons to upgrade would be greatly increased speeds and improved print quality. While researching this article, I came across my 1993 review in Compute! Magazine of the 55-pound HP LaserJet 4, which extolled its 600dpi resolution, its blazing speed of 8ppm, and its low price of just under $1,800. How times change! A modern mono laser like HP’s LaserJet Pro M404dn is several times faster than its ancestors, weighs under 20 pounds, and costs only a few hundred dollars. It may not stay viable as long, but replacing it is much less of an expensive hassle.

The 1993 HP LaserJet 4 was an impressive behemoth, but 18 years later, the smaller, lighter, and cheaper LaserJet Pro M404dn runs rings around it.

How A Laser Printer Works

Laser printers can be used in a home office or a small business office. Office connectivity is typically via an Ethernet connection. In a home office or small business, a cable or Wi-Fi are used to connect the printer to computing devices. Wi-Fi is also used to connect mobile devices to printers for mobile printing.

Laser printers can handle both black and white and color printing, though color laser printers are more expensive than monochrome laser printers. Typically, laser printers are used for printing whereas newer all-in-one printers can function as a printer, copier, scanner and fax. Many have user-friendly touchscreen displays.

The following steps detail how a laser printer works:

  • A photo, graphic or text image is sent to the printer, which begins the process of transferring that image to paper using a combination of positive and negative static electric charges.
  • The revolving drum gets a positive charge.
  • The system’s electronics convert the image into a laser beam.
  • The laser beam bounces off a mirror onto the drum, drawing the image on the drum by burning a negative charge in the shape of the image.
  • Then the drum picks up the positively charged toner from the toner cartridge. The toner sticks to the negatively charged image on the drum.
  • Paper entering the printer receives a negative charge.
  • As the paper passes the drum, the paper’s negative charge attracts toner from the positively charged drum the toner literally sits on top of the paper.

    Laser printers are trustworthy, long-lasting machines. You only need to get new toner once in a blue moon, and the inside parts rarely malfunction.

    Under the hood, a laser printer is a rather ingenious combination of photosensitive parts, lasers, electrically charged ink, and heating units. All of these work together to produce that incredibly crisp, warm print within seconds.

    Today, well discuss a key part of this construction: the printer drum – used to transfer your image to paper. What is a printer drum, how does it work, and how do you know when your printer needs a new one? Read on to find out.

    Printer Speed: Who’s Faster

    Let’s address this one first, because it’s easy to glance at speed ratings and say that inkjets are slower than lasers. The cheapest inkjets are indeed slower than the cheapest lasers. That does not mean, however, that all inkjet printers are slow .

    Because of the way laser technology maps and applies toner to an entire page all at once, it’s inherently faster than the way most inkjets apply ink to papersending a printhead with an array of nozzles back and forth across a page, spraying line after line of ink. Some entry-level inkjets can only crank out 8 pages per minute or less, whereas many low-end laser printers can push paper at twice that rate.

    A different kind of inkjet: HP’s PageWide business printers reach speeds as high as 70ppm.

    However, when you compare higher-end, office-oriented inkjets with comparable color laser AIOs, speeds aren’t that far apart. Brother’s MFC-J6945DW inkjet, for instance, prints at 22ppm, versus the 25ppm of the same company’s laser-based MFC-L3770CDW. Also, HP offers a line of inkjets, including the PageWide Pro 552dw, with fixed, full-width printheads that span the page and are capable of peak print speeds around 70ppm.

    WINNER: Laser, but not by much

    Are Printer Drums Replaceable

    Yes! Just as youll need a new toner cartridge once yours runs out, your printer will also need a new drum one day.

    As a rule of thumb, its time to get a new imaging drum after you use up four or five standard toner cartridges.

    More specifically, a drums lifespan depends on its maximum number of rotations, and its ability to fully erase the previously printed image off its surface. If your printer stops producing crisp prints, chances are that a new imaging drum can help.

    Who Invented Laser Printers

    Until the early 1980s, hardly anyone had a personal or office computer the few people who did made”hardcopies” with dot-matrix printers. These relatively slowmachines made a characteristically horrible screeching noise because they used a grid of tiny metalneedles, pressed against an inked ribbon, to form the shapes of letters, numbers, and symbolson the page. They printed each character individually, line by line, at a typical speed of about 80 characters per second, so a page would take about a minute to print. Although that soundsslow compared to modern laser printers, it was a lot faster than most people could bash out lettersand reports with an old-style typewriter . You still occasionally see bills and address labels printed by dot-matrix you can always tell because the print is relatively crude and made up of very visible dots. In the mid-1980s, as computers became more popular with small businesses, people wanted machines that could produce letters and reports as quickly as dot-matrix printers but with the same kind of print quality they could get from old-fashioned typewriters. The door was open for laser printers!

    You Might Be Wondering: What Is The History Of Laser Printers

    The Science of Printing | HP LaserJet | HP

    The rise of laser printer technology has its roots in the dot-matrix printers and mimeograph machines of the 1950s and 60s.

    Who invented the laser printer?

    Well, IBM pioneered the dot-matrix printer in 1957 and Xerox released its first photocopier two years later.

    The dot-matrix printing method used an ink ribbon and a series of tiny dots to render low-resolution images and text.

    Laser printers are similar to photocopiers, however, the photocopier, by contrast, used a novel and dry printing technology called xerography. Once called electrophotography, xerography used a positive and negative electrical charge to attract toner particles onto paper. The particle would stick to charged areas on the page.

    In 1967, an enterprising engineer at Xerox named Gary Keith Starkweather came up with the idea of photocopiers producing images sent directly from a computer. Although his supervisors at Xerox frowned on the idea, Starkweather pursued this unique printer concept.

    Starkweather modified a copier, replacing the imaging unit with a laser beam and an eight-sided rotating mirror. The laser left a positively charged image on the surface of a sheet of paper. Negatively charged toner particles attached themselves to paper, and a heating element fused them to the page.

    The Best Inkjet Printers We’ve Tested

    Both of these examples feature six ink cartridges instead of the usual four. The four standard process colors of cyan, magenta, yellow, and black all that a color laser printer is capable ofare supplemented by additional inks such as the light magenta and light cyan of the XP-8600. The Pixma adds a richer pigment black and a photo blue that increases detail and widens the color gamut. These extra colors also reduce color striations and graininess. On the higher end, Canon, Epson, and HP also make professional-grade printers that produce truly eye-popping output for graphic artists and photo pros. The Epson SureColor P5000 deploys 11 inks, while Canon’s imagePrograf PRO-1000 has 12 .

    Many consumer photo printers deploy five or six ink colors for a richer palette.

    Also, most inkjet printers support borderless output, meaning that they can apply ink up to the very edge of the paper for a professional finishing feature known as a “bleed.” Some output, especially photos, makes a better impression without a blank margin. Inkjets can also print on not only plain, glossy, and semi-gloss paper but even some other materials, such as certain types of cloth or vinyl. Laser printers are limited to only a few types of paper, many of them formulated especially for laser toner, giving you a narrower range of professionally designed and decorative documents.

    Laser printers excel at meeting font foundry specs for character shape, kerning, spacing, and leading.

    Print Speed And Text Print Quality

    When it comes to printing black and white text pages, laser printing is unbeatable in its speed.

    Even in low-end cheaper monochrome laser models you can expect print speeds of up to 20 pages per minute. Inkjets are significantly slower, with budget printers rarely printing more than 6 pages per minute of black text. It is for this reason that business users often find value in laser printers that home users may not. When you’re printing a seven-page document, the speed differential doesn’t matter that much as it would with a seventy page one.

    For normal print sizes text printing quality is similar between both laser and inkjet printing platforms. However, if your printing needs include printing small fonts then lasers are normally superior to inkjets, as the fusing technology better lends itself to the minute curves and dots of small text.

    Inkjet Printer Vs Laser Printer

    Printers are all about papers and liquid ink or a standard toner cartridge with a bit of touch of electricity. Even though liquid ink is costly, it works for a long time until its time to get new ink cartridges.

    Printing usually depends on printer owners. If you want an occasional printer for printing colorful photos, then inkjet is the one for you. Inkjets make print jobs more accessible and require less mess.

    Similarly, laser printers are suitable in their print job, especially for office workers, since they prefer faster printer speed. The only problem is that it is costly and comes up with even more expensive toner cartridges.

    Once you are done buying a printer, the only thing that should bother you is the ink costs.

    What Is A Laser Printer

    A laser printer is a popular type of computer that uses a non-impact photocopier technology where there are no keys striking the paper.

    When a document is sent to the printer, a laser beam “draws” the document on a selenium-coated drum using electrical charges. The drum is then rolled in toner, a dry powder type of ink that adheres to the charged image on the drum. The toner is transferred onto a piece of paper and fused to the paper with heat and pressure.

    The laser printer was popularized in the mid-1980s as a standalone printer for use with personal computers. It typically replaced an impact dot matrix printer or a non-impact inkjet printer. Laser printers are still often connected directly to a single PC, but today many are linked to local area networks , supporting workgroups or entire departments.

    In some cases, a laser printer is used as a multifunction peripheral with printing, scanning, photocopying and fax capabilities. These devices are known as multifunction printers . They usually have MFP or MFC for multifunction center as part of their model numbers.

    What Is A Laser Printer And How Does It Work

    Many computer and technology experts believe that we will no longer need physical documents in the future. Everything will be completely digital, so we wont have to print any more text documents, art pieces, designs, flyers, or anything else we can physically hold in our hands.

    Every year, we move closer and closer to that reality, but we arent speeding towards it. A completely 100% digital world wont be here until 2050, at least, and it probably takes longer, so printed papers still hold value in the world we live in now.

    And since you live in the year 2021, you will need a printer to print. But which one should you use? There are thousands of printers out on the market today, so theres one out there that fits your needs. One popular type of printer that may be able to fit your needs is a laser printer.

    Laser Printers can be a great basic printer for people who are new to computers or an advanced machine that is ready to take on any print job you throw at it. But what is a laser printer, and how does it work?

    How Do Laser And Inkjet Printers Work

    One of the fundamental differences between inkjet printers and laser printers is how they operate. Although they both produce crisp, clean text and images, how they do this is very different.

    • Inkjet printers use small nozzles that emit ink droplets directly onto the paper. This method lends itself to brightly colored images and is a good choice if youre looking to produce high-resolution photos, graphics, or images in your documents.
    • Laser printers use toner powder instead of dye or pigment-based ink. Laser printers produce electrostatically charged dots on a light-sensitive drum which attracts toner powder. The toner is transferred to the paper and fixed by a heating process. Laser printers deliver crisp black and white and brilliant color prints.

    What Is The Difference Between A Laser Printer And An Inkjet Printer

    Laser Printers – CompTIA A 220-1001 – 3.11

    Before you buy a printer in Malaysia, you should think about the differences between laser printers and inkjet printers.

  • Functionality

    The type of cartridges used by each printer is the main difference between laser and ink printers. Toner cartridges are used by laser printers, while inkjet printers utilize ink cartridges.

    A laser printer operates an electrical charge to direct where and when toner should be sprayed onto the paper. On the other hand, Inkjet printer technology is a little more basic, as ink is dispensed as the cartridge travels over the page.

  • Costs

    There are several costs connected with choosing the best printer for your needs. A laser printer’s initial investment can be significantly higher than an ink printer’s, with laser printers being the more expensive alternative.

    The expense of buying and changing cartridges is also something to think about. Toner replacements are often more costly. Although ink cartridges are less expensive, they may need to be replaced more frequently.

    In the long run, this might raise your costs. Investing in remanufactured cartridges is another option for lowering expenses even more.

  • Quality

    When it comes to print quality, the combination of a laser printer and a toner cartridge will give you better results. A laser printer’s accuracy is difficult to match with an inkjet printer.

    When using an ink printer, the paper may be more prone to smudging or deterioration while the ink is still wet.
