1, resolution: The image of printer or monitor is careful the measurement of degree and clear degree. The resolution of printer is measured with every inches check the number, as more as element, resolution is higher, clearer. Monitor is used measure like always. Use Dpi commonly (Dot Per Inch) express.

2, Cpi: , every inches inside contains character number, with the size that will show character, span.

3, Ppm: Paper Per Minute, express to print rate

4, Ipm: Image Per Minute, state image prints rate

5, Cpl: , the character that every place in travel contains several, use the width that shows character and span.

6, Cps: , the character that every second can print several, with the printing speed that will express printer. General with 10cpi literal Fu Weiji comes to computation to print rate definitely on the west.

7, Lpi: , every inches inside contains linage, with will show the size in perpendicular direction character, span.

8, collateral interface: Transmit a byte (8) data, have 3 kinds of transmission pattern:

9, ECP: Enhance ability port, those who be aimed at is printer and scanner

10, EPP: Enhance collateral port, the dispute printer peripheral that be aimed at

13, USB1.1/USB2.0: A kind of more new-style interface technology, transmission speed differs somewhat: USB1.1: 12Mbps/s; USB2.0: 480Mbps/s. USB2.0 is OK and comprehensive compatible USB1.1. Feature: Transmission rate is rapid; Supportive Plug and Play and heat are inserted unplug; Support a variety of equipment link.

14, SCSI: It is the abbreviate of interface of all of small-sized computer science department, the rapiddest now transmission rate has achieved 160MbpS, can join at the same time 7 to 15 equipment.

15, IEEE1394: High-speed is serial bus line, transmission speed can achieve 400Mbps/s; Apply to the facility that needs transmission mass data.
