     SELECTING AND CONFIGURING A PRINTER DRIVER

     Harvard Graphics 3.0 and follow these steps:

     1.   At the [F6]- Main Menu, select [8]-Setup menu.

     2.   Select [5]-Printer 1 Setup Menu.

     3.   With the cursor highlighting the "Printer type" selection, press
          [F3]-Choices to see a list of printers.

     4.   Use the "arrow" keys to scroll through the list of printer
          drivers, highlight the "LaserJet 4L (HPGL/2)" printer driver,
          then press [Enter].

     5.   Press [Tab] to highlight "Output port," then press[F3]-Choices
          to list available ports.  Select the parallel port your printer
          is using, then press [Enter].

     6.   Press [Tab] to highlight "Default paper size."  Press [F3]-

     Note   Setting "Use spooler" to "Yes" initiates the Harvard Graphics
            internal printer spooler which will allow you to return to
            work within Harvard Graphics sooner after printing.  If you
            select "No" for this option, you will have to wait until the
            entire print job has completed to continue working.

            If you are using another print spooler,(a hardware spooler or
            a software spooling utility, for example), you should select
            "No" for the "Use spooler" option.  Do not use the Harvard
            Graphics spooler while any other spooler is active.

     8.   Press [Tab] to highlight "Quality", press [F3]-(Choices),
          highlight High, Medium or Low print quality, then press [Enter].
