will investigate is changing the width of the characters that Delta prints.
Changing the print pitch
In “printer talk,” character width is called pitch. Normally, Delta prints 10 characters per inch. This is called pica pitch because it’s the same spacing as a standard pica typewriter.
Delta can also print 12 characters per inch. This is called elite pitch because it is the same spacing as an elite typewriter.
Condensed print is approximately 17 characters per inch (actually it’s 17.14 characters per inch). Condensed pitch allows you to get 136 columns of printing on an 8% inch page.
You tell Delta which pitch you want to use with the (ESC) “B” command. The table below shows the three options of this command.
| Table |
| |
| Print pitch | commands |
|
Pitch | Characters/inch | Control code | |
Pica | 10 | (ESC) | “B” CHR$(l) |
Elite | 12 | (ESC) | “B” CHR$(2) |
Condensed | 17 | ‘,ESC) | “B” CHR$(3) |
Let’s see how these three pitches look. Try this program:
NEW
18 LPRINTCHR$(27)"B" CHR$(2)
2@ LPRINT "THIS IS ELITE PITCH PRINTING"
30LPRINTCHR$(27)"B" CHR$(3)
40LPRINT "CONDENSEDIS THE NARROWESTPITCH"
50LPRINTCHR$(27)"B" CHR$(l)
60LPRINT "NOW WE ARE BACK TO PICA PITCH PRINTING"
When you run this program you should get this:
THIS IS ELITE PITCH F’HiNTING
CONDENSED IS THE NARROWEST PITCH
NOW WE ARE BACK TO FICA PITCH F’RINTING
