In addition to smearing, gradual fading of many inks can be a problem over time. Print lifetime is highly dependent on the quality and formulation of the ink. The earliest inkjet printers, intended for home and small office
applications, used dye-based inks. Even the best dye-based inks are not as durable as pigment-based inks, which are now available for many inkjet printers. Many inkjet printers now utilize pigment based inks which are highly water resistant: at least the black ink is often pigment-based. Resin or silicone protected photopaper is widely available at low cost, introducing complete water and mechanical rub resistance for dye and pigment inks. The photopaper itself must be designed for pigment or for dye inks, as pigment particles are too large to be able to penetrate through dye-only photopaper protection layer. The highest-quality inkjet prints are often called " giclée " prints, to distinguish them from less-durable and lower-cost prints. However, the use of the term is no guarantee of quality, and the inks and paper used must be carefully investigated before an archivist can rely on their long- term durability. To increase the durability of inkjet printer prints, more attention is needed for the inkjet ink cartridge. One way to treat ink cartridges on an inkjet printer is to maintain the temperature of the printer itself. Excessive variation in space temperature is very bad for printer ink cartridges. The user should prevent the printer becoming too hot or too chilly as the cartridges can dry up. For lasting printer efficiency, the user should ensure the area has a regular and steady temperature level.

(April 2012) ( Learn how and when to remove this template message ) Inkjets use solvent-based inks which have much shorter expiration dates compared to laser toner, which has an indefinite shelf life. [ citation needed ] Inkjet printers tend to clog if not used regularly, whereas laser printers are much more tolerant of intermittent use. [ citation needed ] Inkjet printers require periodical head cleaning, which consumes a considerable amount of ink, and will drive printing costs higher especially if the printer is unused for long periods. If an inkjet head becomes clogged, third-party ink solvents/head cleaners and replacement heads are available in some cases. The cost of such items may be less expensive compared to a transfer unit for a laser printer, but the laser printer unit has a much longer lifetime between required maintenance. Many inkjet printer models now have permanently installed heads, which cannot be economically replaced if they become irreversibly clogged, resulting in scrapping of the entire printer. On the other hand, inkjet printer designs which use a disposable printhead usually cost significantly more per page than printers using permanent
