But remember that you are not to send those spaces ifyou send commands
to the printer.
To sum up, printercommands are of two types. Acw?trol code isasingle-
character command thattells your printer to do something, like move down
one line. An Escape sequence controls aprinter operation too, but is more
than onecharacter long. Since they arecommands, neither control codes nor
escape sequences are usually printable characters.

Most software packages already include the printer commands they need.
The programs that sendcommands to the printer so you don’t have to enter
them yourself are calledprinter dri~’ers.
Many programs ask you to installor configure your printer, which usually
means keying intoamenu the particular setup information describing your
StarLaserPrinter 4111.Youenter such things as how you want to underline,
alter line spacing,or move to anew print position.
Someprograms, such as WordPerjict and the systems from Lotus Develop-
mentCorporation, let youput printerEscape sequences beforeor right inside
thedocument you want to print. Toturn on boldface, for example, you might
hold down special keys on your keyboard, often Iabelled CONTROL or
ALT,as youpress anotherkey. Or youmight useaspecial Functionkey, such
as F6.
In fact, to take real advantage of your Star LaserPrinter 4111’sspecial
abilities, you might opt for aword processor that lets you specify font
changeseasily. WordPerfect and Microsoft Word are strong at this, but are
by no means the only good font manipulators.
If you have trouble using aparticular program with your Star LaserPrinter
4111,you’ll probably get answers most quickly by asking your software
supplierhow the program interacts with your printer.
