before printing. This program gives you a left margin of 10 wd a right margin of 60, but you Call use wy numbers you prefer for the margin commwds. 5 OPEN4,4 10 PRINT#4, CHR$(27)"X"CHR$(10);CHR$(60) 20 CLOSE4 In Microsoft BASIC, the program is : 5 LPRINT CHR$(27);"X";CHR$(10);CHR$(60) Such a program will also allow you to choose the margins you prefer for program listings. Just remember that once you run a program that sets margins, those margins are in effect until you chwge them with new margin commwds or turn off or reset the printer. You should be aware that a few applications programs reset the printer before each document or file they print.
These programs will, of course cwcel your new margin settings. The maximum right margins on the MPS 1000 printer are 80 in pica, 96 in elite, wd 137 in condensed. For further information on this com- mwd see Appendix B. Skip Over Perforation If you are using continuous pin-feed paper for printing program list- ings or other material not conuolled by w applications program, you may find the MPS 1000 prints right over the perforations between pages. The MPS 1000 has w ESCape code to prevent this: the ESCape "N" commwd. You send ESCape "N" followed by the number of lines you wwt the MPS 1000 to skip at the bottom of a page.
For exam- ple, in Commodore BASIC the following line will make the MPS 1000 skip six lines after each 60 lines: 10 PRINT#4,CHR$(27) "N"CHR$(6); In Microsoft BASIC, the commwd is: 10 LPRINT CHR$(27) "N"CHR$(6); Since a stwdard page is 66 lines, this will give you one inch of blank space at the bottom of each page. If you prefer to have half of the blank space at the top of the page wd half at the bottom, simply set the top of page approximately three lines (1I2 inch) below the perforation. Line Spacing Ordinarily you don't have to worry about how the printer moves the paper so that it doesn't print lines of text on top of each other; the MPS 69
