commands to do this. ESCape "O" decreases the line spacing to 9-dot (9/72-inch), ESCape "1" decreases it to 7-dot, and ESCape "2" sets line spacing to a value defined by ESC ''A:.' . For example, in Commodore BASIC the following lines will set the MPS 1000 line spacing to 13 dot: 5 OPEN4,4 10 PRINT#4, CHR$ (27);''.A";CHR$(13) 20 PRINT#4,CHR$(27);"2" 30 CLOSE4 In Microsoft BASIC; the commands are: 5 LPRINTCHR$(27); "N'; CHR$(13) 10 LPRINT CHR$(27); "2" In addition, there are commands to specify the line spacing in 72nds of an inch and 216ths of an inch. If you need to make such fine adjust- ments in the line spacing, see Appendix B for the proper commands.
In the chapter on dot graphics you will see how useful ESCape '' 1'' can be. Paper-out Sensor Under the platen (the black roller) of your MPS 1000 printer is a small switch that senses whether or not paper is in the printer. When the end of the paper passes this switch, it sends a signal that sounds the beeper and stops your printing. This saves wear on your print head, ribbon and platten, but because of the distance between the switch and the print head, it stops the printing about 2 inches from the end of the page. Therefore, if you use single sheet paper in your MPS 1000 you can't print on the last 2 inches of each page without an adjustment.
See Appendix D for deactivating paper-out sensor. 71
