3. At the end of the hexadecimal dump, set the printer off-line with the

On Line switch. This is necessary to print the last line.

The following BASIC program is a simple test you can run in hexade-

cimal mode:

10 FOR I-O *TO 255 20 LPRINT CHR$(I); 30 NEXT I 40 LPRINT 50 END

If your system passes the codes directly to the printer without changing

them, you will get a printout like Figure 2-5.

Most BASICS, however, are not quite that straightforward. For example,

the IBM-PC prints the following.
