But remember that you are not to send those spaces if you send commands
to the printer.
To sum up, printer commands are of two types. A cw?trolcode is a single-
character command that tells your printer to do something, like move down
one line. An Escape sequence controls a printer operation too, but is more
than one character long. Since they are commands, neither control codes nor
escape sequences are usually printable characters.

Most software packages already include the printer commands they need.
The programs that send commands to the printer so you don’t have to enter
them yourself are called printer dri~’ers.
Many programs ask you to install or configure your printer, which usually
means keying into a menu the particular setup information describing your
Star LaserPrinter 4111.You enter such things as how you want to underline,
alter line spacing, or move to a new print position.
Some programs, such as WordPerjict and the systems from Lotus Develop-
ment Corporation, letyou put printer Escape sequencesbeforeor rightinside
the document you want to print. To turn on boldface, for example, you might
hold down special keys on your keyboard, often Iabelled CONTROL or
ALT, asyoupressanotherkey.Or you might usea special Function key, such
as F6.
In fact, to take real advantage of your Star LaserPrinter 4111’sspecial
abilities, you might opt for a word processor that lets you specify font
changes easily. WordPerfect and Microsoft Word are strong at this, but are
by no means the only good font manipulators.
If you have trouble using a particular program with your Star LaserPrinter
4111,you’ll probably get answers most quickly by asking your software
supplier how the program interacts with your printer.
