DESCRIPTION:

This document explains the installation and use of an Autodesk Device
Interface (ADI) plotter driver for the COMPAQ PageMarq 15 and 20 laser
printers.  The driver is designed to run with AutoCAD and AutoSketch in
the "real" mode on DOS systems.  A "protected-mode" plotter driver for
AutoCAD Releases 10/386 and higher is also available and is described in a
separate document.  We recommend that you use the "protected-mode" driver
if you are able.

This driver is a product of and is supported by COMPAQ Computer
Corporation, not by Autodesk.


HOW TO USE:

INSTALLING THE DRIVER SOFTWARE

The driver for AutoCAD and AutoSketch is contained in the file
PMARQADI.COM, which is about 8000 bytes long.  You will probably want to
install a copy of this file in the same directory where you store AutoCAD
or AutoSketch.  For example, to copy the file from disk drive A to a
directory named ACAD on drive C, use the DOS copy command:

      C:> COPY A:PMARQADI.COM C:\ACAD

This plotter ADI driver must be installed (loaded into memory) prior to
entering AutoCAD or AutoSketch.  The driver is a "terminate and stay
resident" (TSR) software program.  Once loaded, it remains in memory until
you turn off or reboot your computer or uninstall the driver using the
uninstall option.

To install the driver, enter:

      C:> PMARQADI

The driver will then be installed with the following defaults:

Input from AutoCAD or AutoSketch (rather than from a file).
Output directly to the printer.
Printer connected to parallel port 1 (LPT1).
Messages displayed on monitor (AutoSketch is off).
Printer settings will be reviewed at each plot time.
Use interrupt 78(hex).
Paper will come from upper cassette.
Paper is letter size.
One copy per plot.
Line width units will be in dots @ 400 dpi = .0025 in.

To change this setup, you can include one or more option codes on the
command line.  If you use more than one code, separate each by a space.
The options and codes are listed below:


         CODE      OPTION

INPUT:   Vxx       use interrupt Vector xx hex, default is V78
         Ifilename Input from binary file named "filename"
         U         Uninstall driver from memory

OUTPUT:  LPTx      output to parallel port LPTx, x=1 to 4, default is LPT1
         COMx      output to serial port COMx, x=1 to 4
         Ofilename Output to file named "filename"
         Wx        line Width units x: (default 4 is dot width @ 400 dpi)
                       1= 1 mm, 2= 0.1 mm, 3= 0.01 in, 4= 0.0025 in
DISPLAY: A         disable screen messages for AutoSketch
         H or ?    display this Help screen
         D         Disable review of options at plot time

PAPER:   F         printer has a multipurpose Feeder 
         Nx        Number copies x: 1-99, 1 is default
         Tx        paper Tray x: 1-4,1=upper(default),4=manual or feeder
         Px        Paper size x from list below, default is Letter size

PAPER SIZES:
1=executive 7.25 x 10.5 in    5=a5    148 x 210 mm    9=b4  257 x 364 mm
2=letter    8.5  x 11.0 in    6=b5    182 x 257 mm   10=a3  297 x 420 mm
3=legal     8.5  x 14.0 in    7=a4    210 x 297 mm
4=ledger   11.0  x 17.0 in    8=folio 210 x 330 mm


As an example, one could install the driver using a combination of the
above options:

      C:> PMARQADI LPT2 N2 P3 F T4

This will install the driver into memory.  When plotting, the driver will
send output to the printer connected to parallel port LPT2.  The printer
will make two copies using legal size paper from the installed
multipurpose feeder.  The following is a detailed explanation of each
option.


INPUT OPTIONS: Vxx, Ifilename, U

Vxx         Interrupt Vector option.  The driver will be installed into
            the computer's memory as a terminate-and-stay-resident
            program.  The driver will wait for input from AutoCAD through
            interrupt xx, where xx is the hexadecimal interrupt number.
            Use this if you have interrupt conflict problems.  Usually the
            default V78 will work.

Ifilename   Input file option.  The driver will look for the AutoCAD
            BINARY plot file named "filename" as input directly from your
            disk drive.  "filename" can be an valid DOS path and file
            name.  AutoCAD binary printer plot files usually have the
            extension .plt .  This option does not install the driver as a
            TSR.  See the section titled "USE AS A POSTPROCESSOR" for more
            details.

U           Uninstall option, no inputs.  This will override all other
            options and will remove the driver from memory.  Terminate-
            and-stay-resident programs such a this driver must be removed
            in the reverse order of their installation.  Put the command
            PMARQADI U at the end of the batch file that you use to invoke
            AutoCAD.  Then the driver memory will be released to other
            applications when you switch out of AutoCAD.


OUTPUT LOCATION OPTIONS: LPTx, COMx, Ofilename

Choose ONE of the following:

Ofilename   Output file option.  Output will go to a file for printing at
            a later time.  This will create an file named 'filename' for
            later printing.  This is useful for printing copies of a plot
            without needing to be in the AutoCAD environment, or for use
            with a spooler.  Using this option as a TSR with AutoCAD, you
            will be able to change the output file name within AutoCAD
            before creating each plot.  The output file created can be
            directly sent to your printer using the DOS copy or print
            commands.  See the section titled "OUTPUTTING FILES FOR DIRECT
            PRINTING FROM DISK" for more details.

LPTx        Output will go to printer connected to parallel port LPTx
            where x is 1 to 3.

COMx        Output will go to printer connected to serial port COMx where
            x is 1 to 4.  Consult your printer user's manual for
            interfacing details.

Default     Equivalent to option LPT1.  If an output options is not
            specified, output will go to printer connected to parallel
            port LPT1.


OUTPUT APPEARANCE OPTION

Wx          Line Width units option.  You can print different line widths
            by assigning different line types (1 to 127) to each color in
            your drawing.  The line widths will the line type number times
            line width unit selected by this option.  Choose x as follows.
            The default is x = 4.

                 x =   1     1  mm
                       2     0.1 mm
                       3     0.01 in
                       4     0.0025 in (equal to dots @ 400 dots per inch)



DISPLAY OPTIONS: A, H, D, and ?

A           AutoSketch option.  Use this option if you are using
            AutoSketch.  It will disable the display of driver messages on
            your monitor while printing.  This will avoid corruption of
            the screen display of your AutoSketch drawing.  However, you
            will not see certain driver status messages.

H or ?      Help options.  This option will override all others and
            display on the monitor a help screen listing all of the
            options.  The driver does not become memory resident.

D           Disable review option.  Disables review of the following
            settings at each plot time: output file, paper cassette, paper
            size, and number of copies.  This option may be usefull if you
            use AutoCAD scripts for plotting.


PAPER HANDLING OPTIONS: F, Nx, Px, and Tx

Tx          Tray option.  This selects the source of paper.  The default
            is the upper or only cassette (1).  The driver supports manual
            feed or a multipurpose feeder and up to three different
            cassettes.  Choose x as follows:

                 x =   1     Upper tray (default)
                       2     Lower tray
                       3     Bottom tray (for three tray printers only)
                       4     Manual Feed or Multipurpose Feeder

            If the multipurpose feeder is installed, you must also include
            option code F below.

F           Multipurpose Feeder option.  Use this code to indicate that a
            multipurpose feeder is installed on the printer.

Nx          Number of copies option.  Replace x with the number of copies
            desired for each plot.  The default is one copy.

Px          Paper size option.  Replace x with the number corresponding to
            the desired size from the list above.



CONFIGURING AUTOCAD FOR THE ADI PLOTTER DRIVER

It is necessary to reconfigure AutoCAD for an installed ADI plotter
driver.  You will need to do this once before you use the ADI driver for
the first time.

To configure AutoCAD, first select the configuration option at AutoCAD's
main menu.

At the configuration menu, choose the option (number 2) to allow detailed
configuration.  And then enter Y (yes) to confirm that you want detailed
configuration.

Next, select the Plotter configuration option (number 5).  Then, select
the Autodesk Device Interface plotter, which applies to real-mode ADI
plotter drivers.  Do NOT choose the "ADI P386" option, which applies to
protected mode drivers.  On early versions of AutoCAD, you might have to
tell AutoCAD where to find the generic ADI plotter driver file that comes
with AutoCAD.  If so, it is in a AutoCAD driver file called PLGEN.DRV.
Next, answer the questions to configure an ADI plotter:

1.  Select output format as an Installed ADI driver.

2.  Select the same interrupt that you used when installing the driver in
    memory.  The default of V78 is usually OK.

3.  Select multiple pens, and set the number of pens to 100.  The pen
    numbers will correspond to ploted grayscales.  More on this below.

4.  Select multiple dashed-line styles, and set the number to 127.  Rather
    than dashed lines, the plotter will interpret the line style as the
    line width.  More on this below.

5.  Choose no variable pen speed.

6.  Set the maximum horizontal (X) width and maximum vertical (Y) height
    to the maximum plot size for the largest paper size that you will use.
    Make the X width the smaller dimension (portrait orientation).  See
    the table below which shows paper and maximum plot sizes.

7.  Set the number of plotter steps in both the X and Y directions to 800
    dots per inch.  Note however that the driver will cause the printer to
    operate at 800 x 400 dpi resolution.

8.  Pen motion optimization: select 0 for no optimization.  Due to a quirk
    in AutoCAD, pen and pattern numbers greater than 42 will not plot if
    pen sorting is turned on.

 10. A3              297  x  420  mm      284  x  411  mm


Paper and plot dimensions are always specified in portrait orientation,
width less than height.


For further information see:  the plotter configuration section of the
Installation & Performance Guide to AutoCAD; the plotting section of your
main AutoCAD Reference Manual; and your printer User's Manual for printer
details.

AutoCAD will now be configured to do a printer plot using the installed
plotter driver.


CREATING PLOTS WITH THE DRIVER

To send plots to the printer from AutoCAD's drawing editor, type the
AutoCAD command 'plot' at the command line.  Alternately, from AutoCAD's
Main Menu, select the Plot option.  After specifying the plot area,
AutoCAD will display the current plot settings.  Select to change these
settings if you want to gain access to the color, line type, and pen
settings.  (See below for information on linewidths and grayscales).

Make any changes and confirm your choices.  Make sure your printer is
connected, turned-on and on-line, and hit return when ready.  Then your
plot will be produced on the printer.

To abort the plot, type CTRL-C.  If you get an "Abort,Retry ?" message,
check that your printer in on-line, and then enter R for retry.


PAPER ORIENTATION

The coordinate system used by the plotter driver and printer assumes the
paper is in portrait orientation, width less than height.  When
considering how your plot will look on the paper, specify 0 rotation for
portrait orientation.  To get a plot in landscape orientation, use
AutoCAD's 90 degree plot rotate option.  You will set the default rotation
during AutoCAD's configuration dialogue.  The rotation can be reset before
each plot.


LINE WIDTHS and GRAYSCALES

To each color in your drawing, AutoCAD will assign a plotter pen and a
plotter linetype.  You can adjust these assignments at each plot time.

The plotter driver and printer will use the linetype value to set the
width of the plotted lines.  The units are selected by the option code Wx
described above.  For example, is option code 4, the default was selected,
linetype 6 is 6 x 0.0025 in = 6/400 dpi = 0.015 inches wide.  Linetype is
0 the printer minimum of 1/400 inch.

Be careful with filled solids and wide polylines.  AutoCAD expects a
specific pen width (AutoCAD's default is 0.01 inches) for drawing filled
entities with multiple line passes.  IMPORTANT: If you plot filled
entities, change AutoCAD's overall pen width setting to be the same as
your choice using the linetype setting.  AutoCAD asks for a default pen
width during the configuration dialogue, and AutoCAD's pen width setting
can be reset before each plot.  For example, if you keep AutoCAD's default
width of 0.01 inches, the set linetype to 4 with linewidth units equal to
0.0025 inches.  Then the resulting linetype width (4 x 0.025 = 0.01) will
match the default width.

The plotter driver and printer will use the pen number (0 through 100) to
set the grayscale pattern for each drawing color.  Pen numbers 0 and 1
print solid black.  Pen 100 prints all white.  Pens in between print
shades of gray.


OUTPUTTING FILES FOR DIRECT PLOTTING FROM DISK

You may wish to create a file that may be plotted directly from disk.
Once a file is created, you can then print using the DOS copy command
without running AutoCAD.

Here is an example:

Say you want to produce a plot of the columbia.dwg.  Install the plotter
driver using option O by typing:

    C:> PMARQADI Ocolumbia.prn 

Run AutoCAD and plot the columbia.dwg file.  The file columbia.prn will be
created on the default disk for later printing from the command line.
Beware of certain messages that will come from AutoCAD which will seem
unusual when you are creating these output files.  After you request a
plot, AutoCAD displays the plot settings.  AutoCAD will give the status
message "Plot will NOT be written to selected file".  This is alright,
because it refers to AutoCAD's binary plot file format, not to the
printer-ready files created by this memory resident driver.

Later, the driver will ask for you to confirm the output file name.  You
may enter another name, at this time, or press enter to accept the command
line entry.  Also, AutoCAD will still request you to do plotter setup and
to "Press RETURN to continue".  When this occurs, simply hit RETURN, and
the driver will create the output file.


Assuming your printer is connected to LPT1, you can then print later by
using the DOS copy command.

    C:> COPY COLUMBIA.PRN LPT1


USE AS A POSTPROCESSOR

The ADI plotter driver can also work as a postprocessor, reading AutoCAD
ADI binary files from your disk and sending them directly to the printer.
First, plot to an ADI binary plotter file from AutoCAD or AutoSketch.
This is done by configuring AutoCAD or AutoSketch for binary-file output
rather than for the installed interrupt driver.  Then, when the Autodesk
product is no longer running, you may use the driver to plot from the
binary file to your printer.

Here's an example.  Say you want to produce a plot of columbia.dwg.
First, run AutoCAD's configuration program to select the ADI Printer and
plot to binary file.  Use the PLOT command in AutoCAD.  This produces a
binary plot file called "columbia.plt".  Next, exit AutoCAD and plot the
drawing by invoking:

    PMARQADI Icolumbia.plt 

This will cause the driver to make a plot of the contents of the file
"columbia.plt".  When the plot is done, the  driver will vanish from
memory (it does not install itself as it would if you wanted to plot
directly from AutoCAD).


USE WITH AUTOSKETCH

The driver can be used with AutoSketch.  Just remember to use the A option
code on the control line.  Failure to do this will cause the driver to put
messages on the AutoSketch screen, overwriting the pulldown menu there.

AutoSketch must be reconfigured so that it knows you will be using an ADI
driver to do printer plots.  To initiate AutoSketch's reconfiguration
type:

     C:>SKETCH /R   (AutoSketch 3.0 uses -R)

Configure AutoSketch's plotter as a Autodesk Device Interface Plotter.
AutoSketch will then prompt you to give it more information regarding this
ADI driver.  See the previous section titled 'CONFIGURING AUTOCAD FOR THE
ADI DRIVER'.  Then follow the instructions in configuration and
installation sections of your AutoSketch manual.

When you open the plot area dialogue box, the values for x and y may be
incorrect.  Set them now, to the size of the paper you have in your
printer.  Remember that the driver assumes that the paper is in the
portrait orientation.  Rotating the plot will be necessary for landscape
oriented plots.

Before every plot from AutoSketch, make sure that the printer is turned-
on, connected and on-line.  Failure to do this will return you to the
drawing screen with out any error messages.  If the printer goes off-line,
runs out of paper or becomes disconnected at any time during the plot, no
more data will be sent to the printer and you will be returned to the
drawing screen again without any error messages.  If your drawing is not
being plotted at all or stops plotting and you are returned to the drawing
editor, make sure the printer has paper, is turned-on and is on-line.


TIPS AND HINTS

Here are some tips for using the driver:

    1. If you will use the driver with every session of AutoCAD, you may
    want to place the PMARQADI command in your AUTOEXEC.BAT file with the
    correct options set, because you must install the driver after every
    reset of your system.  Or put the PMARQADI command in a batch file
    which you use to invoke AutoCAD or AutoSketch.  Also put the command
    PMARQADI U at the end of this batch file to remove the driver from
    memory when it is no longer needed.

    2. It is good practice to save your work before beginning a printer
    plot.  Sometimes when aborting a plot, especially if the printer has
    not been set on-line properly, DOS will put you out of AutoCAD and
    back to the DOS command line.  If this happens, unsaved work may be
    lost.
