I
This program will print one line using several printing features. Then it “calls” the macro in line 60. When line 80 prints the style is “plain vanilla” because the macro has reset it.
10LPRINTCHR$(27); “Q”;CHR$(40);
20 LPRINTCHR$(27); “a” ;CHR$(2);
30 LPRINTCHR$(27);
40LPRINTCHR$(27); “h” ;CHR$(1) ;
50 LPRINT “TESTINGABCD”
60 LPRINTCHR$(27); “+’’; CHR$(1) ;
70LPRINT “TESTING ABCD”
80END
■Reading a hex dump
The BASIC in some computers changes ASCII codes before they send them to the printer. If you run into problem because of this, try this hex dump to check the ASCII codes.
First turn off the printer. Hold down both the Paper Feed key and Mode key and turn on the printer, and run the following pro- gram.
10 FOR 1=0 TO 255
20LPRINTCHR$(I ) ;
30NEXT I
40LPRINT
50END
If your system passes the codes directly to the printer without qhanging them, you will get a printout like this. (You can print out the last remaining line in the print buffer by putting the printer off line with the On Line key.)
