APPENDIX A: MISCELLANEOUS NOTES

A.1 Notes on Printing and Paper Feeding

1)Because the TM-T81 printer is a line printer, it automatically feeds paper after printing the data.

Therefore, when the line spacing for one line is set to a smaller value than the print data, paper may be fed more than the set amount just to print the data.

For example, when the line spacing for one line is set to 10 dots (10/180 inches) and only paper feeding is executed, paper is fed for 10 dots; however, if bit-image characters are printed, paper is fed for 24 dots. (See Table A.1.)

When only rotated characters are printed on one line, paper feeding is executed as shown in Table A.1.

Table A.1 Paper Feeding Amount

		Required Paper Feeding Amount (dots)
Normal Characters	Font A	24 ⋅ number of times enlarged in vertical
	Font B	17 ⋅ number of times enlarged in vertical
Rotated Characters	Font A	12 ⋅ number of times enlarged in vertical
	Font B	9 ⋅ number of times enlarged in vertical
Bit image (ESC ∗)		24

2)When the printer goes to the standby (data-waiting) state during printing, it temporarily stops printing and feeding paper. When data is transmitted and printing is executed, paper may shift 1 to 3 dots from the print starting position, which especially affects bit-image printing.

3)Interval of autocutting operation in the receipt section

For driving the auto cutter of the receipt section, take the interval as a minimum of 10 lines of printing or paper feeding (to prevent small pieces of cut paper from dropping into the auto cutter).
