Dedicated photo printers differ from all-purpose printers as they are designed to print photos only, as opposed to text or graphics documents in increasing to photos. They are generally covenant in size and lightweight, and some models even feature batteries that allow you to print without the need for an outlet. Most photo printers, along with dye-sublimation (or dye-sub) printers, are built nearby a thermal dye engine, though there are a few that feature inkjet technology.
For many years, dye-sublimation printers were devotee devices used in demanding illustrated arts and photographic applications. The advent of digital photography led to the entry of this technology into the mainstream, forming the basis of many of the standalone, portable photo printers that surfaced in the second half of the 1990s.

The term "dye" in the name refers to the solid dyes that were used in the process instead of inks or toner. "Sublimation" is the scientific term for a process where solids (in this case, dyes) are converted into their gaseous form without going straight through an intervening liquid phase.
The printing process employed by true dye-sublimation printers differs from that of inkjets. Instead of spraying tiny jets of ink onto a page as inkjet printers do, dye-sublimation printers apply a dye from a plastic film.
A three-pass theory (featuring solid dyes in tape form on whether a ribbon or a roll) layers cyan, magenta, yellow, and black dyes on top of one another. The print head on a dye-sub printer uses tiny heaters to vapourise the dye, which permeates the glossy outside of the paper. A clear coat is added to safe the print against ultraviolet light. Although this method is capable of producing excellent results, it is far from economical. Even if a single image does not need any one of the pigments, that ribbon segment is still consumed. This is the fancy it is tasteless for dye-sub printer compatible paper packs to contain a exchange film capable of producing the same whole of prints. In addition, dye sublimation inks need a paper that allows the ink to remain on the outside of the paper.
Nowadays, a whole of inkjet printers on the store are capable of deploying dye-sublimation techniques. The cartridges in such printers spray the ink, outside the page one strip at a time. The print head heats the inks to form a gas, controlled by a heating element that reaches temperatures of up to 500° C (higher than the median dye sublimation printer). A big dissimilarity in the results with dye-sublimation technique is that because the dyes are applied to the paper in gas form, they do not form safe bet dots with a hard edge like inkjet printers. Instead, the edges are softer and blend into each other easily. Additionally, the infusion of the gaseous dye into the paper yields a more colour-fast picture.
Comparing Dye-Sublimation Printers and Inkjet Printers
Although it is difficult to point out every potential benefit and disadvantage when comparing inkjet and dye-sub printers, the following list mentions the major points that apply to most citizen printing photos at home.
Advantages of Inkjet Printers over Dye-Sub Printers:
· Prints are very strict with sharp edges
· Latest models offer unbelievable information that exceeds most dye-sub printers
· Variety of papers/surfaces available--including matte, luster, glossy.
· Not locked in to one manufacturer's paper
· Some archival inkjets can furnish prints that long-lasting
· Most inkjets can print on many different surfaces that are designed to accept ink, along with Cds, Cd inserts, envelopes, etc.
· Inkjets have a considerably larger colour gamut and regularly furnish more vivid photos than dye-subs
· Easier to gather large format inkjets that can print 11x14, 13x20 sizes, or larger
· Inkjet printing is often economy than dye-sub printing
Inkjet Printer Disadvantages:
· Often much slower than dye-sub printers
· Most non-archival inkjets furnish prints that fade a small (sometimes a lot) faster than dye-sub prints
· Print heads sometimes clog and wish cleaning, or even replacement
Advantages of Dye-Sub Printers over Inkjet Printers:
· Very fast
· Relatively maintenance-free
· Smooth with no dot patterns visible, even under magnification
· Produce excellent shadow information in dark areas where some inkjets may be "blotchy"
· Prints are regularly more durable and more waterproof than inkjet prints
· For many viewers, dye-sub printers furnish photos that look and feel more like real photographs due to the smoothness of the prints and the absence of illustrated dot patterns
Dye-Sub Printer Disadvantages:
· Consumer level models often smear high dissimilarity edges (like a black square on a white background) to some degree, manufacture charts, graphs, and line art look a small less "precise"
· Dye-sub prints typically only last as long or slightly longer than a good non-archival inkjet printer and are generally not carefully "archival"
· Paper type option is very small and while dye-sub printers furnish excellent glossy photos, most fall behind or do not even offer the option of matte prints
· Dye-sub printers use an entire page and an entire page worth of ribbon even to print one small wallet size photo
· Pages cannot be regularly fed straight through the printer twice to fill more of the page as they can in inkjets
· Dust can sometimes get inside and cause vertical scratches on prints
· Dye sub printing and the cost of paper and toner (ribbon) is often higher than inkjet printing
