Common Technical Terms For Printers（2）

21. Page Length: The number of lines that can be printed in the longitudinal length of the paper.

22. Character structure: Print the vertical or horizontal dot matrix of character Chinese characters.

23. Enter time: refers to the time required after the print head prints one line to the terminal (right end) and then returns to the starting print position (ie, the left end).

24. Line feed time: refers to the time required to change from the current print line to the next line. It is related to the line spacing, and the line spacing is long.

25. Printing direction:

(1) One-way printing: The print head is returned to the beginning of the line after each line of printing.

(2) Two-way printing: When the printing of the line ends, regardless of the position of the line where the print head is located, it first judges who is closest to the position of the first or last print information. If it is close to the end of the line, the print head moves directly to the end of the line and reverses to the first line of the line. If it is close to the line, it moves to the beginning of the line and then prints in the forward direction.

26. Degree of travel: refers to the maximum distance from the reference position when the same needle prints a line.

27. Arrangement: refers to the maximum distance from which any column of points is offset from the reference position.

28. Point Density: The number of dots printed by the print needle per unit length of the printer, in points/mm (DPMM) or dots (DPI). The dot density is also known as the print resolution.

29. Word Density: The number of characters that can be printed on the unit length of the paper. The unit is a large number of characters and is expressed in CPI. Printers usually give a standard word density and can be expanded or compressed as needed.

30. Line Density: The number of lines that can be printed on the unit length of the paper, expressed in lines per inch.
