There are lots of different types of graphics cards, but they all feature a GPU, some RAM, and a fan to keep it cool.

The benefits to graphics cards is that you can find one powerful enough for any task. They don’t share system memory, and—in most systems—are easy to upgrade. On the negative side, they’re expensive, larger, and generate a lot of heat.

You’ll usually see dedicated graphics cards in mid-range or better desktop computers. Some higher-end laptops also have them.

 solid ink printer. solid ink printer. A laser-class printer that uses solidwax inks that are melted into a liquid before being used. Instead of jetting the ink onto the paper directly as inkjet printers do, solid ink printers jet the ink onto a drum.  A better registration of color is obtained by transferring the ink to the drum first and then to the printer, because the drum can be more tightly controlled than moving paper. 🐵🐵🐵🐵🐵

   
    

This is the technical bit! Sublimation printing is the application of sublimation inks onto a surface using a heat press to provide the required combination of heat, time and pressure. This combination causes the inks to be converted from a solid to a gaseous state enabling them to penetrate the sublimatable surface so that a permanent, full colour image is formed. The colour penetrates the surface of the item so that the result is colourful, long lasting and resistant to scratching unlike some other printing methods that merely print onto the surface of the item.

Dye sublimation printing is always done on a polyester, polymer, or polymer coated item. At high temperatures, the solid dye converts into a gas without ever becoming a liquid. The same high temperature opens the pores of the polymer and allows the gas to enter. When the temperature drops, the pores close and the gas reverts to a solid state. It has now become a part of the polymer. For this reason true dye sublimation cannot be done on natural materials such as 100% cotton. Natural fibres and non-coated materials have no "pores" to open.
