<Features of DIGITAL Laser Printer LN15 printer driver>
    The DIGITAL Laser Printer LN15 printer driver has the following features:

    (a)  Support of Graphics mode
         Graphics mode is supported by the DIGITAL Laser Printer LN15 printer
         driver.
         It can be set in the [Graphics Mode] combo-box of the [Options] dialog
         box.
         Graphics mode gives better performance by using a DIGITAL original data
         compression method.

         If there are problems printing in this default mode change the
         Graphics mode setting to Raster and try printing again. For details
         see the Options dialog help.

         Raster      : This is the optimum mode when printing a document
                       containing alot of text.
         Graphics    : This is the optimum mode when printing a document
                       containing intricate graphics.
         EX          : This is the optimum mode when printing a document from
                       an application like MS-Excel containing multiple
                       calculations.

    (b)  Support for 3 types of Graphics quality.
         [HIGH],[MEDIUM],[LOW] can be selected from the [Graphics Quality]
         combo-box in the [Options] dialog box. These settings change the
         resolution of graphics causing a noticeable variance in print
         results and printing time.

    (c)  Support for Smoothing(FEIT)
         FEIT is a function which corrects the jaggedness of print. It can
         be set from the [Options] dialog box.

    (d)  Advance Options Dialog box
         By selecting the Options button while keeping the Ctl keyboard button
         depressed an Advanced Options dialog box will be displayed. This
         includes settings for advanced users. For details see the Advanced
         Options dialog help.

      device=DIGITAL Laser Printer LN15,DECLN31L,LPT1:

    [PrinterPorts]
      DIGITAL Laser Printer LN15=DECLN31L,LPT1:,15,45

    [devices]
      DIGITAL Laser Printer LN15=DECLN31L,LPT1:

    Note: The printer driver should only be removed from Windows' Control
          Panel.


<Limitations of printer driver>
    The DIGITAL Laser Printer LN15 printer has the following limitations.

    (1)  When Graphics Mode is Raster, most of the rasterizing is done by the
         display driver. If print results differ noticeably from what is
         displayed on screen, upgrade the display driver to the most recent
         version and try printing again.

    (2)  If print data overlaps into the unprintable area of the printer some
         data may not be printed. In this case adjust the margin settings and
         try printing again.

    (3)  When printing from Microsoft Windows 3.1 Notepad, printing at 600dpi
         resolution may not produce the desired results.
         In this case set the resolution to 300dpi before printing.

    (4)  Most applications use driver functions and settings in the normal
         way, but there may be some applications that read driver settings
         at start-up time only, or change some control panel settings while the
         application is running, or change printer settings from the
         applications [Printer Settings] option etc. Operation of the driver
         may be unstable after such cases.
         If possible set up the the printer in the windows Control Panel before
         running an application. 

    (5)  When using Corel Ventura (Corel Co.), before starting up the
         application the printer environment should be set up in the Windows
         Control panel.

    (6)  When using MS-EXCEL, printer set-up should be executed from the
         [Page Layout] dialog of the File menu.
         Otherwise the intented settings (Paper Size etc.) may not be used.

    (7)  When a print job is cancelled while printing, if the data lamp of the
         printer operator panel remains on, turn the power switch off and on
         once, before using again.

    (8)  If there is insufficient memory available in Windows,the desired
         printing results may not occur. In this case,increase total Windows
         memory by increasing the size of the Swap file in the Control Panel
         and try printing again.

    (9)  When using "Print True Type Fonts as Printer Fonts" in Raster Mode,
         depending on the application characters may be clipped or shortened
         and not print correctly.
         If this happens, please use Graphics Mode.
