A printer turns digital files from your computer into physical paper documents

A printer is a device that connects to your computer and produces paper copies of documents, photos, and other files you create or read. When you send a file to print, the printer receives the data, processes it, and uses ink or toner to put an image on paper. Most printers sit on a desk or table and plug into power; they connect to your computer through a USB cable, Wi-Fi, or a network connection.

The basic job is the same across all printers: take what's on your screen and make it physical. But printers differ in speed, quality, cost per page, and what they can handle. Some print only in black and white. Others print in color. Some can also scan documents or copy them without a computer. Choosing the right one depends on what you actually print and how often.

Key Takeaways

  • Inkjet printers are cheaper upfront but cost more per page; laser printers cost more initially but are cheaper to run if you print regularly.
  • Color printing costs significantly more than black-and-white, whether you use ink or toner.
  • Multifunction printers scan and copy as well as print, saving desk space if you need those features.
  • Wireless printers let you print from phones and tablets, but USB-connected printers are simpler to set up and more reliable.

Inkjet versus laser: the two main printer types

An inkjet printer sprays tiny dots of liquid ink onto paper to form text and images. It works like a pen — the more you print, the more ink you use. Inkjet printers are inexpensive to buy, often between $50 and $200, which is why they are common in homes. The downside is that ink cartridges are expensive relative to how much you get, and they dry out if you don't print regularly.

A laser printer uses heat and a rotating drum to fuse powdered toner onto paper. Laser printers cost more upfront — typically $200 to $500 for a basic black-and-white model — but the toner lasts much longer and costs less per page. If you print dozens of pages a week, a laser printer will save you money over time. If you print a few pages a month, an inkjet makes more sense.

Inkjet printers are also better for photo printing because they can blend colors more smoothly. Laser printers produce sharper text and are faster, but they are not ideal for photographs unless you buy a specialized photo laser printer, which is expensive.

Color printing costs more than black-and-white

Every printer can print in black and white. Adding color means buying and replacing colored ink or toner cartridges in addition to black. A color inkjet cartridge costs roughly as much as a black cartridge, so printing one color page can cost two to three times as much as printing in black alone.

If you only need color occasionally — for a school project or a birthday flyer — a black-and-white printer is the practical choice. You can always print color documents at a library, school, or print shop for a few dollars. If you print color regularly, a color printer is worth the cost, but budget for higher ongoing expenses.

Multifunction printers combine printing, scanning, and copying

A multifunction printer (also called an all-in-one) prints, scans documents into your computer, and makes copies without needing a computer. These machines cost slightly more than a printer alone but take up less desk space and handle three jobs. If you need to scan receipts, copy a form, or print a document, a multifunction printer does all three.

The trade-off is complexity. Multifunction printers have more parts that can break, and the scanning and copying features add buttons and settings you may not use. If you only print and never scan or copy, a dedicated printer is simpler and often cheaper.

Wireless printers versus USB-connected printers

A wireless printer connects to your home Wi-Fi network, so you can print from your phone, tablet, or any computer on the network without plugging in a cable. This is convenient if you move around or have multiple devices. Setting up wireless printing requires entering your Wi-Fi password into the printer, which can be fiddly the first time.

A USB printer plugs directly into your computer with a cable. Setup is faster — plug it in and install the driver software — and there are fewer connection problems. USB printers work reliably but tie you to one computer unless you unplug and move the cable. Most modern printers offer both options: USB and Wi-Fi.

If you have only one computer and rarely print from other devices, USB is simpler. If you print from a phone, tablet, or multiple computers, wireless is worth the extra setup time.

Speed and page yield matter if you print a lot

Printer speed is measured in pages per minute (ppm). A basic inkjet prints 10 to 15 pages per minute. A laser printer typically prints 25 to 40 pages per minute. If you print one or two pages a week, speed does not matter. If you print dozens of pages a day, a faster printer saves time.

Page yield is how many pages a cartridge or toner cartridge will print before running empty. Manufacturers estimate this based on average coverage — usually 5 percent of the page is covered in ink or toner. A high-yield cartridge costs more upfront but prints more pages, lowering the cost per page. If you print rarely, a standard cartridge is fine. If you print hundreds of pages a month, high-yield cartridges save money.

Durability and repair costs vary by brand and model

Some printer brands are known for lasting years with minimal problems; others fail within a few years or develop paper jams and connection issues. Canon, HP, and Brother are common in homes and have parts available if something breaks. Cheaper no-name brands may be harder to repair.

Before buying, check online reviews from people who own the specific model. Look for comments about reliability, how often paper jams happen, and whether replacement parts are straightforward to find. A printer that costs $20 less but breaks after a year costs more in the long run than a reliable model that lasts five years.

Frequently Asked Questions

Do I need to keep a printer turned on all the time?

No. Printers can stay off until you need them. Turning a printer on and off does not damage it. Wireless printers may take a few seconds to connect when you turn them on, but USB printers start when ready. Leaving a printer on wastes electricity, so turning it off when you are not printing saves money.

Can I use third-party ink cartridges instead of the brand name?

Yes, but with caveats. Third-party cartridges cost less but may not print as well or last as long. Some printers have chips that detect non-brand cartridges and refuse to work. Read reviews of the specific cartridge and printer model before buying to see if others have had problems.

What is the cheapest way to print if I only print a few pages a month?

Buying a printer is not worth it if you print rarely. Libraries, schools, and print shops charge 10 to 25 cents per black-and-white page and more for color. Over a year, printing a few pages a month at a shop costs less than buying a printer and replacing dried-out cartridges.

Can a printer work without internet?

Yes. USB printers work without internet — they only need to connect to your computer. Wireless printers need Wi-Fi to print from phones or tablets, but can print from a computer on the same network even if the network is not connected to the internet. Some wireless printers can also print from a USB drive without any computer.

How do I know which printer will work with my computer?

Most modern printers work with Windows, Mac, and Linux computers. Check the printer's specifications or manual to confirm it supports your operating system. The printer manufacturer's website has driver software you read and install to make your computer recognize the printer.
