Naming and using commands
In order to use printer commands, you should know how they are
recognized by your software program. The most common way of
naming codes or commands is with one of two numbering systems,
decimal or hexadecimal.
The decimal system is the standard numbering system based on units
of ten, using the numerals 0-9.
The hexadecimal, or hex, system is based on units of 16, and is often
used by programmers. Instead of using only the numerals 0 through 9,
the hex system also uses the letters A through F. For example, the
decimal numbers 9, 10, 11, and 12 are 09, OA, OB, and OC in hex.
Since the most frequently used hexadecimal numbers are between 0
and FF hex (0 to 255 in decimal), it’s common to write hexadecimal
numbers that are less than 16 with a zero in front, as shown above.
In this book, hex numbers are distinguished from decimal numbers
by the word hex after them (for example, 1B hex). Other common ways
of denoting a hexadecimal number are the following:
1BH
$lB &lB &H1B
<lB>H
The Command Summary and the Quick Reference Card give both
the decimal and hex numbers for each command.
Word Processors
In many ways, word processors demand the most from your printer
When you create and print a document, you may use many print styles
and fonts, reformat pages, add headers and footers, and use bold, italic,
and other effects.
Once you have installed your word processor by using the lists on
page 3-1, you can ordinarily use a fixed set of printer features by using a
word processor command to place markers around the text to be
altered. When the document is printed, the markers are recognized and
translated into suitable commands for your printer. On your screen
some programs show the markers in a distinctive way while others
display the text as it will appear-for example, in bold or italics.
