Top and bottom margin commands

Function				Control code
Set	top margin		to n lines	(ESC	> “r”	CHR$(n)
Set	bottom	margin to n lines		(ESC)	“N”	CHR$(n)
Cancel top		and	bottom margins	(ESC)	“0”

In both cases the value of n tells your printer how many lines to skip, although there is a slight difference in the usage. When you set the top margin with (ESC) “r” CHR$(n), the value of n tells the printer what line to start printing on. When you set the bottom margin with (ESC) “N” CHR$(n), the value of n tells the printer how many blank lines should be left at the bottom of the page.

Let’s try a simple application to see how these margins work. Enter this program, which will print 150 lines without top and bottom margins.

10' Demo of top and bottom margins

60 LPRINT CHR$(12); : ' form feed

70FOR I=1 TO 150

80 LPRINT "THIS IS LINE";1

90NEXT I

110LPRINT CHR$(12); : ' form feed

120END

When you run this program it will print 150 lines right down

the page and across the perforations. When it’s done line 110 - sends a form feed to advance to the top of the next page.

Now add the following lines to your program. (Don’t forget the semicolons or you won’t get quite the same results that we did.)

20' Leave 6 blank lines at the bottom of page

30LPRINT CHR$(27);"N";CHR$(6);

40' Start top of page at line 6

50LPRINT CHR$(27);"r";CHR$(6);

100 LPRINT CHR$(27);"0" : ' clear top and bottom margins"
