Lexmark T640tn 1200 x 1200 DPI A4

The general trademark of a manufacturer by which the consumer knows its products. A manufacturer can have multiple brand names. Some manufacturers license their brand names to other producers.
Product name:
Product name is a brand's identification of a product, often a model name, but not totally unique as it can include some product variants. Product name is a key part of the Icecat product title on a product data-sheet.
Product code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. We map away wrong codes or sometimes logistic variants.
Laser printers are devices that print high quality text or illustrations fast. They do so by very accurately applying toner (a kind of ink powder) to the paper and then heating the paper so the toner will melt and stick to the paper.
