Two ways to put marks on paper
An inkjet printer fires very small droplets of liquid ink through nozzles in a print head, and the ink soaks into or sits on the paper. A laser printer works differently. It uses a light source to form an electrostatic image of the page on a drum, powdered toner clings to that image, and the toner is transferred to the paper and fused by heat.
Both technologies come in small home models, and both are sold as printers and as all-in-one devices with a scanner. Neither is better in every situation. The right choice depends on what you print and how often.
Cost patterns
There are two costs to consider: the purchase price, and the cost of keeping the printer supplied.
Inkjets often have a lower purchase price, particularly for color models. Supplies tend to be ink cartridges, and the cost per page can be higher on models that use small cartridges. Some inkjets use refillable tanks, which usually cost more up front but can reduce the cost per page.
Laser printers often cost more at the start, though basic black-and-white models can be affordable. Toner cartridges cost more per cartridge, but each typically prints more pages, so the cost per page is often lower for text. Color lasers use several toner cartridges, and a complete set can be a significant expense. Some laser printers also have separate drum units that wear out and need replacement.
These are general patterns, not rules. Check the page-yield figures that makers publish and divide the cartridge price by the stated pages for a rough comparison. Real results depend on how much of the page is covered, and the ways to reduce waste are covered in the guide to ink and toner habits.
Speed
Laser printers are typically faster at printing multi-page text documents, and they handle stacks well. They may take a moment to warm up before the first page, because the fuser has to heat.
Inkjets are often slower on long jobs, particularly at high quality settings, though many are fast enough for normal home use. Photo printing on an inkjet at the highest setting can be slow, since the head makes many passes.
Text quality
Laser printers are well known for crisp, sharp black text, and the toner stays on the surface of the paper, so it does not spread. Smudging is uncommon once the page has come out. Laser text is also usually water-resistant, whereas many inkjet inks can run if a page gets wet, although this varies by ink type.
Inkjets can also produce clear text, particularly on suitable paper, but cheap plain paper can cause slight feathering where ink spreads into the fibers.
Photo and color quality
For photographs, inkjets generally have the advantage. They can blend subtle color tones and often handle glossy photo paper well. Some inkjets use extra ink colors for finer tonal range. Color laser printers can produce good graphics and charts, but photos usually look better from an inkjet using appropriate photo paper and the right paper-type setting.
If photos are a significant use, the quality of your scanner also matters when digitizing old photos, and the printer’s output quality depends on paper and settings as much as on the machine.
Idle behavior
How a printer behaves when it sits unused for weeks is one of the more practical differences.
Inkjets can suffer if left idle. Liquid ink in the nozzles can dry and clog, and the printer then runs cleaning cycles that use ink. Printing a page every week or two helps, and turning the printer off with its own button lets it protect the head. If a clog does develop, see the article on fixing streaky or faded prints.
Laser printers generally cope better with long gaps, because toner is a dry powder that does not clog. This is why lasers are often suggested for people who print rarely but need dependable output when they do.
Power use differs too. Lasers draw a burst of power while heating the fuser, but both types draw modest power on standby, and a printer left on all day adds to the idle power use of your setup. Use any sleep or auto-off settings and the guidance on power settings to limit it.
Size, noise and upkeep
Laser printers tend to be bulkier, and the fuser area is hot after use, so keep it clear of paper and fingers. Inkjets are often lighter and more compact. Both make some noise, and inkjets can be noticeably noisy when running maintenance routines.
Laser toner is a fine powder, so a spilled cartridge should be handled with care, and makers advise against inhaling it or vacuuming it with an ordinary household cleaner. Follow the manual if any spills. For inkjets, spilled ink stains clothing and surfaces, so keep a cloth handy when changing cartridges.
Which suits which household?
A few general scenarios:
- Mostly text, regular printing, a bit of color now and then. A laser, or a tank-style inkjet, often fits.
- Occasional printing with no urgency. A laser handles idle periods well. A basic inkjet can work if you accept the risk of clogs.
- Photos and school projects in color. An inkjet is generally the better fit.
- A mix of everything. A tank-style inkjet all-in-one or a color laser might both be sensible. Compare supply costs carefully.
