APPENDIX A: MISCELLANEOUS NOTES

A.1 Notes on Printing and Paper Feeding
1) Because the TM-T90 series 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.
When only rotated characters are printed on one line, paper feeding is executed as shown
in Tables A.1 and A.2.
