Based on the technology used, the printer can dikelasifikasikan as follows:
- Daisy-wheel: Similar to a typewriter menngunakan plastic or metal (like a hammer), which is printed every letter that will print such a letter by pressing the tape. Printer type that can only print letters and graphics.
- Dot-matrix: this printer to print characters with emphasis on the ribbon ink pin. Each pin produces a point, and the combination of these points form the characters or illustrations.
- Ink-jet: this printer emits ink on paper. This type of printer can produce text and graphics with high quality.
- Laser: This printer uses the same technology on a copier. These printers can produce text and graphics with a very high quality.

Printer can also be classified based on the following characteristics.
- Print quality or print the output generated by the printer.
- Print speed measured by the characters per second, or pages per minute.
- Impact or non-impact related to the working system printers. Printer with daisy-wheel technology, dot-matrix, and line printers are impact printers, and laser printers with technology and ink-jet is a non-impact printer. The second important difference is the type of printer in kegaduhannya. Impact printer is more noisy than the non-impact printer.
- Printing capabilities associated with the text and graphics. Some printers can print only text and others can print text and graphics.
- Font or typeface that can be printed. For example, dot-matrix printers can print only a few fonts. In contrast, laser printers and ink-jet printers capable of printing fonts that almost infinite.
