DESCRIPTION:

This document explains the installation and use of PLCQPQ.DLL, a
protected mode Autodesk Device Interface (ADI) plotter driver designed
to run the COMPAQ PAGEMARQ 15 AND PAGEMARQ 20 printers with AutoCAD
for Windows.  Along with these instructions, please read the AutoCAD
386 Installation and Performance Guide concerning plotting with
protected mode ADI devices, the AutoCAD 386 Users Guide section on
plotting, and your printer users manual.

The driver supports variable line widths and grayscales.  The driver
supports various paper size features that are available on the
printers.  The driver uses PostScript level 2 page-description language
to communicate vector graphics commands to the printer.  This driver is
a product of and is supported by COMPAQ Computer Corporation, not by
Autodesk.


ADI DRIVERS

This driver is a "protected-mode" ADI plotter driver.  ADI is an acronym
for the Autodesk Device Interface specification that was used to create
this driver.  You can use this driver (PLCQPQ.DLL) with version 12 or
higher of AutoCAD for Windows that supports P386 ADI plotter drivers.
This driver was tested using AutoCAD Release 12 for Windows.  Some
Autodesk products also support "real-mode" ADI drivers.
The protected-mode driver provides the following advantages:

      * simpler installation and configuration
      * automatic adjustment of maximum plot size
        to specified paper size
      * faster operation
      * support for AutoCAD's autospool facility


HOW TO USE:

COPYING THE DRIVER SOFTWARE

Copy the driver software onto your hard disk.  The example assumes that
an AutoCAD directory named \ACADWIN is on drive C and that the
distribution disk for this driver is in drive A.  First change to the
directory where you store AutoCAD. Type:
                        C:> CD \ACADWIN [Return]


Next, insert the diskette with the driver in drive A.  Copy the driver
file to your hard disk. Type:

                        C:> COPY A:plcqpq.dll  C:  [Return]


CONFIGURING AUTOCAD 386 FOR THE PLOTTER DRIVER

Start AutoCAD.  When you choose Configure under the FILE menu,
AutoCAD configuration menu will appear.  Choose configure plotter.
AutoCAD will search for all plotter drivers in the path specified by the
ACADDRV environment variable.  The Compaq printers should appear as one
of the plotter choices.  Choose:

COMPAQ PAGEMARQ - ADI 4.2 by COMPAQ (1.05)


Next, choose the appropriate printer model.  You will need to answer
some questions to configure settings for the printer.  The first
question is:

        Printer resolution
Choice     dots per inch
------  ------------------
  1.    800 x 400
  2.    400 x 400
  3.    300 x 300
Select printer resolution, 1 to 3 ? <1>

Select number 1 for best resolution.

The next question is:

        Select printer's paper size (? for list): <default>

Entering ? will display a list similar to the table below.


        PRINTER PAPER AND MAXIMUM PLOT DIMENSIONS

PAPER   PAPER         PHYSICAL SIZE      MAXIMUM PLOT SIZE
NUMBER  NAME          WIDTH  X  HEIGHT   WIDTH  X  HEIGHT

  1.    Executive     7.25 x 10.5 in        6.8 x 10.1 in
  2.    Letter        8.5  x 11.0 in        8.0 x 10.5 in
  3.    Legal         8.5  x 14.0 in        7.9 x 13.6 in
  4.    Ledger       17.0  x 11.0 in       10.5 x 16.6 in
  5.    A5             148 x 210 mm         136 x 198 mm
  6.    B5             182 x 257 mm         171 x 249 mm
  7.    A4             210 x 297 mm         197 x 284 mm
  8.    Folio          210 x 330 mm         197 x 321 mm
  9.    B4             257 x 364 mm         246 x 355 mm
 10.    A3             297 x 420 mm         284 x 411 mm

Paper and plot dimensions are specified in portrait orientation, width
less than height.  Maximum plot size dimensions are approximately 0.50
inches or 10 to 13 mm less than the paper's physical dimensions.

Choose the paper size that you will use by entering the paper name
(significant letters will suffice, e.g. LET for letter) or number.  Hit
RETURN or the space bar to accept the displayed defaults for this and
the following questions.  The next question is:

        Would you like to change the paper size before each plot? <Y>

If you answer Yes, you will be able to choose the size before each plot,
or accept the default that you chose above.  Otherwise, your choice
above will be used for every plot.

        Does the printer have a multipurpose feeder? <N>

Answer Y or N.

Next, select the paper source.  Selecting a paper tray will establish
the preferred paper source if more than one tray has the same size
paper.  Selecting manual feed or multipurpose feeder will set those as
the only source for the paper size that you select.

        Would you like to change the paper tray or select
        manual feed before each plot? <Y>

Answer Y or N.

        Would you like to select 1 or more copies at plot time? <Y>

Answer Y or N.  If no, then only one sheet is printed for each plot.

If this is a first time configuration of the driver, you will be asked
to select the default grayscales or shadings for each drawing color.
There is additional information on this below.  The normal choice is to
set the printer pen numbers so that all colors print as black.  If
instead you choose Yes, the default pens will be set to grays that
approximate the intensity of the AutoCAD drawing colors.  In either
case, you will be able to adjust the pen settings before each plot.

        Is your printer connected to a <S>erial or <P>arallel port ? <P>

Parallel operation is faster than serial operation.  If you choose a
serial port, additional questions will request the baud rate, number of
data and stop bits, parity and the handshake protocol.  For example
choose: 9600 baud, 8 data bits, 1 stop bit, no parity, and DTR hardware
protocol.  Refer to the printer user manual sections and appendices on
interfacing to help select the appropriate settings for your system.
The settings input at the printer control panel must match your choices
here.  Use the highest baud rate that your printer and serial port can
handle.

Next AutoCAD will ask you to identify the specific port.


After the printer questions, you will then go through additional
standard AutoCAD plotter configuration questions.  During this dialogue,
AutoCAD will ask whether to plot to a file.  If you answer yes, then
AutoCAD will send the printer commands to a file which can be copied to
the printer port to generate a plot at a later time.  If you answer no,
the plot will go directly to the printer though the port that you have
specified to the questions above.  In either case, you will be able to
change your choice at plot time.

Also during the dialogue, you will be asked to specify the default plot
size.  The MAX option is based on the paper size that you chose above.
You will be able to change the plot size before each plot.  And, if you
have enabled paper size changes before each plot, the MAX option will
change accordingly whenever you change the paper size.

If you have any questions see the Configuration section of the
Installation & Performance Guide to AutoCAD.  Also see the AutoCAD
Reference Manual for AutoCAD details, and your plotter User's guide for
plotter details.  AutoCAD will now be configured to plot using the COMPAQ
PAGEMARQ ADI driver.


LINE WIDTHS and SHADING or 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 driver and printer will use the linetype value (0 to 255) to set the
width of the plotted lines.  You are asked, during initial
configuration, to select the units used to set the line widths.  Line
type 0 is always the minimum that the printer can produce.  Choices for
units include printer dots at the resolution that you have chosen.  For
example, at 400 dpi, each dot is 0.0025 inch wide, so linetype 8 is 8 x
0.0025 = 8/400 = 0.02 inches wide.  Other choices for units are 1 mm,
0.1 mm, .01 inch, and .001 inch.

The driver and printer will use the pen number (0 through 100) to set
the shading pattern for each color. 0 gives solid black, and 100 gives
pure white.  Pen numbers in between produce grays.


PLOTTING

Either issue the Plot command from the drawing editor or select the plot
file option, item 3 from AutoCAD's main menu.  Make sure your printer is
connected, is turned on, and is on-line.  After you have selected what
you are going to plot, the current printer settings and the AutoCAD plot
settings will be displayed.

A dialog box will appear to allow you to check and change the plot
settings.  Use the device selection button to select the plotter
configuration that you have set up for the COMPAQ PageMarq printer.
Adjust the plot settings and select OK to begin plotting.

Next, you will be able to change or confirm AutoCAD's plot settings. If
you have enabled plot to file rather than to a port, AutoCAD will ask
for the name of the file.  Note that you can specify a port name here in
the place of a file name to redirect the plot directly to the printer
without generating a file.

Finally, if you have enabled the plot-time copies change, you will be
asked to confirm or change the number of copies for the plot.  If
necessary, abort the plot setup by entering Control-C or CANCEL.


STOPPING THE PLOT

If you wish to stop the plot while AutoCAD is sending vectors to the
printer, abort it in the normal manner (Control-C).


SPOOLING

The driver uses AutoCAD dispatcher functions for all communication with
the printer.  As a result, the driver supports the use of an optional
separate spooler (such as the DOS print routine).  The use and
configuration of a spooler is described in your AutoCAD Installation and
Performance Guide.


PLOT TO FILE TO AVOID STOP FOR HARDWARE SETUP

After you have requested a plot from AutoCAD, AutoCAD will normally
pause for hardware set up.  To resume, you must hit ENTER at your
keyboard.  To avoid this stop every time you request a plot do the
following.  At the AutoCAD configuration menu, select Configure
operating parameters.  Select default plot file name.  Then for the plot
file, enter the name of the port to which the printer is connected.  For
example, if connected to parallel port 1, enter LPT1 for the file name.
Thereafter, when plotting, AutoCAD will think it is plotting to a file,
and so will not stop for a hardware setup.


CONFIGURING AUTOCAD FOR NETWORK PRINTING

The Compaq ADI plotter driver can be configured to send plot data to any
of the computer's parallel and serial ports.  The drivers use AutoCAD
dispatcher functions for direct IO to the ports.  This enables AutoCAD
to redirect data for AutoCAD's spooling and plot-to-file features.
However, because the dispatcher uses low level calls to the port
controllers, network software may not be able to capture plot data
directed to a port.  Also, before sending data, AutoCAD queries the
port.  In a network setup, the port may appear "not ready" to AutoCAD
and the plot will never get going.

The solution for network installation is to route the plot data through
AutoCAD's "plot-to-file" feature.  Name the file to be the port name.
Then AutoCAD will use higher-level operating system calls to send data
to the port, and the network will be able to capture the data.  Here is
how to do the configuration.

A.  Configure default plot file name

First, either from AutoCAD's main menu, or in Release 12 under the Files
pull-down menu, choose Configure.  Next, choose Configure operating
parameters.  Next, choose Default plot file name.

Now, for the file name, enter the name of the port from which the
network will be expecting to capture plot data.  Examples are: LPT1 or
LPT2 or COM1.  Enter just the four characters of the port name, no
period nor extension.  If your network requires plot to an actual file,
enter that directory and file name instead.

B.      Configure plotter

Next, continue through the configuration menu.  If you have not yet
configured the plotter driver, choose Configure plotter at the
configuration menu.  Follow the instructions above for configuration,
with the following changes.  Since we will be plotting to a file, don't
worry about the questions asking you to select the port.  Just choose
anything.  However when you get to the question that asks "Do you want
to plot to a file" enter Yes.

C.      Plot time

Set up the plot as described in your driver and AutoCAD documentation.

In Release 12's Plot Configuration dialogue box, set the "plot to file"
box if it doesn't have an X.  You shouldn't have to, but if you do
select the "File Name" button, enter the networks expected port name as
described above in A.  After entering the port name (no period nor
extension) you may get a message "The specified file already exists.  Do
you want to replace it?".  No problem, because it's a port and will
always already exist.  Answer yes.

Finish up the plot configuration to start the plot.  Your network should
now be able to capture the plot data and send it to the printer.


NOTES ON OPERATION

Here are some tips for using the P386 ADI plotter driver with AutoCAD:


1.  The printer must be connected, turned on, and on line before you
plot using the COMPAQ PAGEMARQ ADI driver.  Save your work before
plotting.

2.  Do not turn the printer on and off in the middle of a plotting
session.  An error message will be displayed if you try to use the ADI
driver to plot directly to the printer while the printer is turned off.

3.   To send a plot file to the plotter, type the following at the DOS
command line:

       copy  filename  lpt(n)     OR    copy  filename  com(n)

where filename is the name of the file you wish to plot and lpt(n) or
com(n) represents the port you have connected to your plotter.  Remember
that if using the serial (com) port, you will first have to issue a MODE
statement to match the serial configuration of your plotter.

4.  Disk Space Considerations:  If you wish to plot to file, please
insure that you have sufficient disk space to do so.  File sizes are not
dependent on the size of AutoCAD's DWG file, rather they depend on the
contents of that file.  This is due to the amount of fill the plotter
must do to plot this file.  Be careful with solid filled objects.  AutoCAD
release 12 sends filled polygon information for solid entities.
