Barcode/Label Printers
 Bar codes can be printed with existing dot matrix or laser printers, but with varying results. Thermal label printers, on the other hand, were designed specifically for the job and are built to produce high-quality text and graphics. They print at fast speeds and can be used to print one label at a time or an entire roll.

 Sometimes you must bring the computer to the bar code, particularly to handle jobs such as warehouse inventory control or freezer applications. A portable data terminal (PDT), a fully programmable hand-held computer, is necessary in such instances.
