Printer Resources & Learning Library
A reference centre for everything printing: a plain-English glossary, how each printer technology works, the basics of maintenance, networking, and troubleshooting, plus buying and compatibility guidance.
Printing Terms, A to Z
Plain-English definitions for the printer and printing terms you are most likely to run into — from DPI and duplex to toner and Wi-Fi Direct.
- AirPrint
- Apple’s built-in printing feature that lets iPhone, iPad, and Mac print to a compatible printer over Wi-Fi without installing any driver or app.
- Bleed
- A small margin of colour or image that extends past the trim edge of a page so that, once cut, the printing runs all the way to the edge with no white border.
- CMYK
- The four ink colours most printers use: Cyan, Magenta, Yellow, and Key (black). Mixing these produces the full range of printed colour.
- Calibration
- Adjusting a printer so colours and alignment come out as intended. Many printers include an automatic alignment or calibration routine in their menu.
- Cartridge
- A replaceable container that holds ink (for inkjets) or toner (for lasers). It clicks into the printer and is swapped out when empty.
- Collate
- A print setting that keeps multi-page copies in order — printing a full set (1, 2, 3) before starting the next set, rather than all page 1s, then all page 2s.
- DPI
- Dots per inch — how finely a printer places dots on the page. Higher DPI means more detail, which matters most for photos and fine graphics.
- Driver
- The software that lets your computer talk to your printer. It translates documents into instructions the printer understands.
- Drum
- A rotating cylinder inside a laser printer that picks up toner and transfers it to the paper. Some printers use a separate drum unit that wears out over time.
- Duplex
- Printing on both sides of the paper. Automatic duplex flips the sheet for you; manual duplex asks you to reload the stack halfway through.
- Dye-sublimation
- A printing method that heats solid dye into a gas that bonds to specially coated paper, producing smooth, continuous-tone photo prints.
- EcoTank / Ink Tank
- An inkjet design that uses large refillable ink reservoirs instead of cartridges, usually lowering the cost per printed page.
- Ethernet
- A wired network connection that plugs a printer into a router or switch with a cable, giving a stable alternative to Wi-Fi.
- Firmware
- The built-in software that runs the printer itself. Updating it can fix bugs and improve compatibility and should be done carefully.
- Fuser
- The heated unit in a laser printer that melts toner so it bonds permanently to the paper. It is why laser prints come out warm.
- GSM
- Grams per square metre — a measure of paper weight and thickness. Everyday copy paper is around 80 gsm; card and photo paper are heavier.
- IP address
- A printer’s unique number on your network. Assigning a fixed IP address can stop a networked printer from going offline when addresses change.
- Inkjet
- A printer that sprays tiny droplets of liquid ink onto the page. Inkjets suit photos and lower-volume printing.
- LED printer
- A printer that works like a laser but uses a fixed row of LEDs instead of a moving laser beam to form the image. The result is similar to laser output.
- Landscape
- A page orientation that is wider than it is tall. The opposite of portrait, it suits spreadsheets, charts, and wide images.
- Laser
- A printer that fuses powdered toner onto the page with heat. Lasers suit fast, high-volume text printing.
- Monochrome
- Printing in a single colour, almost always black. Monochrome printers are cheaper to buy and run when you do not need colour.
- Mopria
- A standard that lets Android phones and tablets print to compatible printers over Wi-Fi without installing manufacturer software.
- Nozzle
- One of the tiny openings in an inkjet printhead that releases ink. Blocked nozzles cause streaks or missing colours and are cleared with a cleaning cycle.
- Portable Document Format — a file type that keeps layout and fonts fixed, so a document prints the same way on any printer or device.
- PPM
- Pages per minute — how quickly a printer prints. Real-world speed is often a little lower than the rated figure.
- Portrait
- A page orientation that is taller than it is wide. It is the standard orientation for letters and most documents.
- Printhead
- The part of an inkjet printer that sprays ink through its nozzles. Keeping it clean and unclogged is key to good print quality.
- Ream
- A standard pack of paper, typically 500 sheets. Paper is often bought and described by the ream.
- Resolution
- The level of detail in a printed image, usually stated in DPI. Higher resolution shows finer detail but can use more ink or toner.
- Spooler
- The service that holds print jobs in a queue before sending them to the printer. Restarting it is a common fix for stuck or frozen jobs.
- Thermal printer
- A printer that forms an image using heat rather than ink or toner — commonly used for receipts, labels, and shipping.
- Toner
- The fine powder a laser printer fuses onto paper. Because it is dry, toner prints resist smudging and water.
- USB
- A cable connection between a printer and a single computer. It is simple and direct but only serves the one device it is plugged into.
- Waste ink pad
- An absorbent pad inside many inkjets that collects ink used during cleaning. When it fills, the printer shows a maintenance error.
- Wi-Fi Direct
- A feature that lets a device connect straight to a printer’s own wireless signal, without both first joining the same router network.
Terminology
Ink versus toner, at a glance
Ink is the liquid an inkjet sprays; toner is the powder a laser fuses with heat. If you are unsure which your printer uses, check what the replacement cartridge is called.
Printer Technologies at a Glance
Every printing method forms an image in its own way. Here is how the common technologies work and where each one fits.
Inkjet
Inkjet printers spray microscopic droplets of liquid ink through a printhead onto the page. The dots blend to form text and images, and colour comes from mixing cyan, magenta, yellow, and black.
Best for: Photos, colour graphics, and everyday home printing at lower volumes.
Laser
A laser draws the image as an electrical charge on a rotating drum, which picks up powdered toner. A heated fuser then melts the toner permanently onto the paper, so prints come out dry.
Best for: Fast, high-volume text printing at a low cost per page.
Thermal
Thermal printers use heat to form an image. Direct thermal printing darkens heat-sensitive paper, while thermal transfer melts ink from a ribbon onto the surface. Neither needs ink cartridges for direct printing.
Best for: Receipts, shipping labels, and barcodes.
LED
LED printers work like laser printers but replace the moving laser beam with a fixed row of light-emitting diodes that charge the drum. With fewer moving parts, the print process is much the same.
Best for: Reliable office document printing, similar in output to laser.
Dye-sublimation
Dye-sub printers heat solid dye into a gas that bonds directly to specially coated paper. Because colours blend smoothly rather than as separate dots, the result is a continuous-tone photo finish.
Best for: Photo prints, ID cards, and smooth continuous-tone images.
Did you know?
Ink-tank printers are still inkjets
An ink-tank printer is simply an inkjet that uses large refillable reservoirs instead of cartridges, which usually lowers the cost per printed page.

Maintenance, Networking & Troubleshooting Basics
Three short primers for the everyday tasks behind a reliable printer. Each links through to the full hub and matching guides.
Maintenance Basics
A little routine care keeps a printer working reliably for years. Most maintenance is quick, safe, and something you can do yourself.
- 1 Keep the exterior and paper path free of dust and stray paper scraps.
- 2 Run a single printhead cleaning cycle only when print quality drops, then print a test page.
- 3 Replace ink or toner when prints fade or the printer reports a cartridge is empty.
- 4 Use a simple power reset for glitches, and a full factory reset only when a guide recommends it.
- 5 Install firmware updates from the manufacturer, keeping the printer powered on throughout.
Networking Basics
Getting a printer onto your network lets every device print to it. Whether you use Wi-Fi or a cable, the setup follows a clear order.
- 1 Decide between Wi-Fi for any device or a wired Ethernet connection for stability.
- 2 Connect the printer to your network from its control panel or companion app.
- 3 Add the printer on each computer, then print a test page to confirm it works.
- 4 Assign a fixed IP address so the printer stays reachable and does not drop offline.
- 5 Print from phones and tablets using AirPrint on Apple or Mopria on Android.
Troubleshooting Basics
Most printer problems come down to a handful of causes. Working through them in order solves the majority of everyday issues.
- 1 Check power and connection first — a printer showing offline is usually still working.
- 2 Restart both the printer and your computer to clear temporary glitches.
- 3 Cancel stuck jobs and restart the print spooler if the queue is frozen.
- 4 Match the symptom to its guide: offline, paper jam, print quality, or an error code.
- 5 Note the exact error code or message before researching a repeating problem.
Compatibility Guides
Cartridges, drivers, and operating systems all have to match your exact printer. Here is what to check so everything works together.
Cartridge & toner compatibility
Every printer takes specific cartridge or toner numbers. Genuine, compatible, and refilled options exist, but the size and chip must match your exact model or the printer may not recognise it.
Driver compatibility
A driver is written for a particular printer and operating system. Installing the driver made for your model and OS version avoids missing features and printing errors.
Operating system support
Printers list which versions of Windows, macOS, Linux, and mobile systems they support. Older printers may lack drivers for the newest OS releases, so it is worth checking before you upgrade.
Driverless printing
AirPrint on Apple devices and Mopria on Android let many modern printers work with no driver at all, which sidesteps most compatibility questions for everyday jobs.
Installing the right driver
The safe order for getting your computer talking to your printer.
- 1 Identify model
- 2 Match your OS
- 3 Download driver
- 4 Install
- 5 Test print
Best practice
Match the driver to your operating system
Install the driver built for your exact printer model and your version of Windows or macOS. Using the wrong driver is a common cause of missing features and print errors.
