MAKING SR-lo/15 PRINT DARKER

SR-lo/15 has very good print density when it’s just printing regularly. But sometimes you may want something to stand out from the rest of the page. SR-lo/15 provides two ways to do this: double-strike and emphasized print. Both of these go over the characters twice, but they use slightly different methods to darken the characters. Let’s try them and see what the difference is.

The following table shows the control codes for getting into and out of double-strike and emphasized modes.

Table 5-7

Print emphasis commands

Function	Mode	Control code
Double-strike ON	STAR	<ESC>	“G”
	IBM	<ESC>	“G”
Double-strike OFF	STAR	<ESC>	“II”
	IBM	<ESC>	“H”
Emphasized ON	STAR	<ESC>	“E”
I	t IBM	1 <ESC >	“I?’	I
Emphasized OFF	STAR	<ESC>	“F”
	IBM	<ESC>	“F”

Try them now with this little program:

10 'Demo double-strike and emphasized.

20 LPRINT CHR$(27) "G" ; 'Double strike on.

30 LPRINT "This line is DOUBLE-STRIKE printing."

44)LPRINT CHR$(27) "E" ; 'Emphasized on.

'-

50 LPRINT "This line is DOUBLE-STRIKE and EMPHASIZED." 60 LPRINT CHR$(27) "H" ; 'Double strike off.

70 LPRINT "This line is EMPHASIZED printing."

80 LPRINT CHR$(27) "F" ; 'Emphasized off.

90 LPRINT "This line is normal printing."

Run this program. The results will look like this:

Thilr linr im DOUBLE-STRIKE printing.

This linm im DOUBLE-8TRIKE and EMPHASIZED.

This line is EMPHASIZED printing.

This line isj normal printing.
