A printer that uses heat to transfer an impression onto paper. There are two kinds of thermal printers:
thermal wax transfer: a printer that adheres a wax-based ink onto paper. A thermal printhead melts wax-based ink from the transfer ribbon onto the paper. When cool, the wax is permanent. This type of thermal printer uses an equivalent panel of ink for each page to be printed, no matter if a full page or only one line of print is transferred. Monochrome printers have a black page for each page to be printed, while color printers have either three (CMY) or four (CMYK) colored panels for each page. Unlike thermal dye transfer printers , also called dye sublimation printers, these printers print images as dots, which means that images must be dithered first. As a result, images are not quite photo-realistic, although they are very good. The big advantages of these printers over thermal dye transfer printers are that they don’t require special paper and they are faster.
direct thermal: a printer that prints the image by burning dots onto coated paper when the paper passes over a line of heating elements. Early fax machines used direct thermal printing.
- Thin Client
(thin klī´&nt) In client/server applications, a client designed to be especially small so that the bulk of the data processing occurs on the server. Although the term thin client usually refers to software, it is increasingly used for computers, such as network computers and Net PCs, that are designed to serve as the clients for […]
- thin provisioning
In data storage terminology, thin provisioning is the term used to describe the consolidation and automated process of allocating just “the exact required amount” of server space at the time it is required. Thin provisioning is most commonly used in centralized large storage systems such as SANs and also in storage virtualization environments where administrators […]
- disk thrashing
In systems that use virtual memory, the resulting condition of a hard drive being used excessively for virtual memory because the physical memory (i.e., RAM) is full. (The process of moving data into and out of virtual memory also is called swapping pages.) Disk thrashing considerably slows down the performance of a system because data […]
(1) In online discussions, a series of messages that have been posted as replies to each other. A single forum or conference typically contains many threads covering different subjects. By reading each message in a thread, one after the other, you can see how the discussion has evolved. You can start a new thread by […]
- thread bump
In online forums and other online discussion spaces bump is the word used to describe an action (e.g. a message post) so that a particular thread is returned to the top in the list of threads. Some users may even post a message with only the word “bump” to indicate they are posting only to […]
