PRINTING DOWNLOAD CHARACTERS

You’ve now defined and sent three characters to your printer. But how do you know that? If you try printing those characters now you don’t get a flask, car and gun. Instead you get .. ( = ). That’s because the download characters are stored in a different part of the printer’s memory. To tell it to look in download character RAM instead of standard character ROM it requires another command:

(ESC)“%“CHR$(n);CHR$(O)

This command is used to select the download character set (if

n=49) or to select the standard character set (if n =48). Let’s try it out. Enter this program:

10 LPRINT CHR$(27>;"%1";CHR$(O);

20 LPRINT CHR$(6O>;CHR$(61>;CHR$(62)

30 LPRINT CHR$(27>;"%O";CHR$(O)

40 END

Voila! It should have printed out the three characters we defin- ed. Your printout should look like this:

(If it doesn’t, check the last program we ran for errors, then rerun it.)

Let’s find out if there are any other characters in the download RAM. Try this program:

10 LPRINT CHR$(27);"%1";CHR$(O)

20 FOR I=32 TO 126

2; ;;X";N; U-W(I);

50 LPRINT

60 FOR I=160 TO 254 '7;g;;"; CHR$(I);

90 LPRINT

100 LPRINT CHR$(27);"%O";CHR$(O)

110 END
