Difference between Laser & Inkjet Printing Systems
1) Reading Material (4 Pages)
Page 1 – Introduction to Printing Systems
Printing is a method of reproducing text and images on paper or other materials. Two of the most widely used printing systems today are Laser Printers and Inkjet Printers.
Laser Printing uses a laser beam, electrical charges, and toner powder to transfer and fuse an image onto paper.
Inkjet Printing sprays tiny droplets of liquid ink directly onto paper through fine nozzles.
Both have advantages and disadvantages depending on cost, speed, quality, and usage needs.
Page 2 – How They Work
Inkjet Printer Process:
Ink cartridges contain liquid ink.
The print head sprays micro-droplets directly onto paper.
Paper absorbs the ink, producing the image.
Excellent for high-quality photo printing.
Laser Printer Process:
A laser beam draws an image on a drum.
The drum attracts toner powder (charged particles).
Toner is transferred to paper using static electricity.
Heat and pressure fuse toner permanently.
Great for fast and sharp text printing.
Page 3 – Key Differences
| Feature | Inkjet Printing | Laser Printing |
|---|---|---|
| Print Quality | Excellent for images & photos (up to 1200–4800 dpi) | Very sharp for text, good for documents (600–1200 dpi) |
| Speed | Slower, especially for bulk printing | Much faster for large volumes |
| Cost per Page | Higher (ink is expensive) | Lower (toner lasts longer) |
| Printer Cost | Low initial cost | Higher upfront investment |
| Durability | Ink can smudge or fade | Toner prints are long-lasting, waterproof |
| Best For | Home, photos, small jobs | Offices, bulk documents, business use |
