Star Micronics SR-10/I5 user manual TOP and Bottom Margins

After you have run this program, turn off the printer and adjust the top of form position. When you turn the printer back on the page length will be reset to its normal setting (usually 11 inches).

TOP AND BOTTOM MARGINS

Many programs that use a printer don’t keep track of where they are printing on the page. This causes a problem when you get to the bottom of a page because these programs just keep

on printing, right over the perforation. This makes it very hard to read, especially if a line happens to fall right on the perforation. And if you separate the pages then you are really in trouble.

Of course SR-lo/15 has a solution to this predicament. SR- 10/l 5 can keep track of the position on the page, and advance the paper so that you won’t print too near the perforation. There are two commands to do this. One controls the space at the top of the page and the other controls the space at the bottom of the page. The control codes are given in the following table.

Table 65

Top and bottom margin commands

Function	Mode		Control code
Set top margin	STAR		< ESC >	“R” CHR!li(n)
	IBM		< ESC >	“r” CHR$(n)
Set bottom margin	STAR	1	<ESC>	“N” CHR$(n)
	IBM	1	<ESC >	“N” CHR!Nnj
Clear top and bottom margins	STAR		<ESC>	“0”
	IBM		<ESC>	“0”

In both cases the value of n tells SR-lo/15 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) in STAR mode, or with < ESC > “r” CHR$(n) in IBM mode, the value of n tells SR-lo/15 what line to start printing on. When you set the bottom margin with c ESC > “N” CHR$(n), the value of n tells SR-IO/l5 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.
