Inkjet printers may have a number of disadvantages:

  1. The print heads may clog when ink dries up in them during a prolonged period of disuse
  2. The ink is often very expensive (for a typical OEM cartridge priced at $15, containing 5 ml of ink, the ink effectively costs $3000 per liter)
  3. Many "intelligent" ink cartridges contain a microchip that communicates the estimated ink level to the printer; this may cause the printer to display an error message, or incorrectly inform the user that the ink cartridge is empty. In some cases, these messages can be ignored, but many inkjet printers will refuse to print with a cartridge that declares itself empty, in order to prevent consumers from refilling cartridges.
  4. The color gamut of inkjet printers is limited
  5. The capacity of ink cartridges is limited; a typical black ink cartridge will print 100-300 pages of text, while a toner cartridge for a laser printer may last 2,500-10,000 pages.
  6. The lifetime of inkjet prints is limited; they may eventually fade and the color balance may change
  7. Some inkjets use multiple-ink cartridges which combine C, M and Y ink tanks; these must be replaced as a unit when only one color runs outs.
  8. For best results, inkjet printers require more expensive paper than laser printers.
  9. Double-sided printing is not usually practical with inkjet printers.
  10. Because the ink used in most inkjets is water-soluble, care must be taken with inkjet-printed documents to avoid even the smallest drop of water, which can cause severe "blurring" or "running." Similarly, water-based highlighter markers can blur inkjet-printed documents.
