Enlarged printing The enlarged mode (sometimes called double width) of the MPS 1000 doubles the width of all the letters, symbols, and graphics charac- ters. This mode produces striking headings and titles. You can see printing in this mode by entering the following program. 10 OPENl,4 20 PRINT#l, CHR$(14)"ENLARGED PRINTING" 30 CLOSEl When you have entered the program, type RUN and press RETURN. You should see the results below. Once you have turned on enlarged printing, it will stay on until you cancel it by using the canceling code or by turning off the printer. You can prove this with another short program.
First erase the other program from your computer's memory by typing NEW and pressing RETURN, but don't turn off your printer. Then type in and run this program. Remember that you run each program by typing RUN and pressing RETURN. NEW 10 OPEN2,4 20 PRINT#2, "THIS IS STILL ENLARGED" 30 PRINT#2,CHR$(15)"NOW ENLARGED IS OFF" 40 CLOSE2 THIS IS STILL ENLARGED NOW ENLARGED IS OFF As you can see, the first line is still in enlarged printing, but the second one is not. The first is enlarged because the previous program turned on enlarged and it stays on until it is turned off.
The second line is in standard printing because the code that turns off enlarged, CHR$(15 ), comes before the words that are printed. On the MPS 1000 printing modes are canceled in three different ways: • With a specific canceling code, such as the CHR$(15) that you used to cancel enlarged printing. By turning the primer off and back on. • Automatically at the end of a line. Unlike enlarged, some printing effects stay on only for one line. Therefore, you don't have to turn them off if you use them for one whole line. 38
