To print a document using a software application program, you have a
computer, an application program and a printer.  Just as you must have an
interface cable to connect your computer and printer, so must you also have
a driver which interfaces your application program with your printer.

A driver is a software program written specifically for an application and
a particular printer model.  A printer driver controls the printer
behavior, loading information from your software and transmitting it to
the printer to create a document.  When you select the print attributes
(bold, italic, etc.) for a document, the software transmits the
corresponding codes to the printer driver.  The driver interprets the
software codes and sends an equivalent series of commands to the printer.
The printer prints the document with the print attributes desired.

The printer driver transmits both characters, numbers and/or symbols for
printing and also instructions in how the data received should be printed.
It has, however, two limitations:

1.  Due to the application software.
    A driver can handle only the information transmitted to it by the
    application program.  If, for example, the application does not handle
    boldface, your printer will never print in boldface, even though it is
    capable of doing so.

2.  Inherent to the driver.
    Only the information contained in the driver program can be acted
    upon.  If, for example, the driver program does not contain the
    instructions for boldface, your printer will never print in boldface,
    even though it is capable of doing so.

To overcome the second limitation, and allow you to use all your printer's
features, the manufacturer has developed, and will contain developing, in
collaboration with software houses, specific printer drivers for the most
common software application packages.

To optimize the use of your printer, use its specific driver which is
either:

  In a diskette supplied with the printer

  Inserted directly in your software application program (just select your
  printer name in the list of printers available), or in a supplementary
  printer driver disk (e.g. Printer Driver Library).

If you cannot find the specific driver for your application program,
contact your dealer for information on its availability.  In the meantime,
you can use a driver corresponding to the emulation in your printer, even
though this will probably not exploit fully all of your printer's
functions and features.

CAUTION:  The driver you select must be compatible with the resident
          printer emulation (HP Deskjet Plus) or with one or other of the
          optional emulation (IBM Proprinter 4207 or EPSON LQ 850)
          installed using an Emulation Card.
