INTRODUCTION
This document explains the installation and use of STAR48E.EXE ver
1.0, an Autodesk Device Interface (ADI) driver designed to run
with STAR SJ-48 in conjunction with AutoCAD. This driver
was developed by STAR Micronics Deutschland GmbH and does not represent
an endorsement of any particular product, including any of the STAR printers.

basis.
HARDWARE REQUIREMENTS
The hardware requirements specific to using the STAR48E printer ADI
driver with AutoCAD.
o This driver is suitable for use with STAR SJ-48
o A parallel card and cable is required as described in the
AutoCAD Installation & Performance Guide.
o Serial output is not supported because the time required to
plot would be unacceptably long.
HARDWARE INSTALLATION
The STAR printer must be connected to the computer with a
standard Centronics-type parallel cable. Chapter 8 of the
AutoCAD Installation & Performance Guide contains all the
information regarding pin connections and switch settings.
COPYING THE DRIVER SOFTWARE
The STAR48E printer ADI (ver 1.0) driver for AutoCAD is 16k bytes
long. The disk also contains a file STAR48E.HLP for on-line command line
options. You will probably want to install the driver in the
same directory where you store AutoCAD. Here's how to copy the
driver software onto your hard disk. (The example assumes an
AutoCAD directory is on drive C and is named ACAD).
1. Change to the directory where you store AutoCAD:
C:> CD ACAD [Return]
2. Insert the ADI Driver diskette in drive A.
3. Copy the driver files to your hard disk:
C:> COPY A:STAR48E.* [Return]
INSTALLING THE ADI STAR48E DRIVER
The AutoCAD STAR printer ADI driver must be installed (loaded
into memory) prior to entering AutoCAD. It is a "terminate and
stay resident" (TSR) software program which can use up to 77K of
RAM depending on how it is configured. Once loaded, it remains
in memory until you turn off or reboot your computer.
To install the driver:
C:> STAR48E [Return]
The STAR ADI driver will then be installed with the following
defaults:
o Interrupt 7b(hex)
o 180 x 180 Dots per inch print density
o 8" Paper width
o Output directly to printer
o Input from AutoCAD
o form feed after every plot
To change this setup, you can choose to include one or more
options on the command line. These options are:
-lx parallel port x
-f plot from a file -v interrupt # -p no form feed -8 8pins
-o plot to a file -q quarter sized mode -dx density x
To set the horizontal plot density
C:> STAR48E -Dx [Return] (where x is 1 to 6 in the following table):
(default is 180 x 180)
x Horizontal Vertical
Density Density
1 60 180
2 90 180
3 120 180
4 180 180
5 360 180
6 360 360
You can also install the driver to write plot files directly to
your disk drive for later printing (this will create a file named
'fname' on your default drive for later printing). This is
useful for printing multiple copies of a plot. See the section
titled "OUTPUTTING STAR48E PRINTER FILES FOR DIRECT PRINTING FROM
DISK" for more details:
C:> STAR48E -Ofname [Return]
You can use the driver to read AutoCAD Binary printer plot files
directly from your disk drive. This allows you to use plotting
modes which would use too much memory for plotting from AutoCAD
as a TSR. This option does not install the driver as a TSR, and
may be used repeatedly. See the section titled "USE AS A
POSTPROCESSOR" for more details:
C:> STAR48E -Ffname [Return]
Note: These filenames must conform to DOS standards.
To install the driver for printing in Quarter Sized Mode. Automatically
the paper width set to 13.6"
C:> STAR48E -Q [Return]
To install the driver to only use 8 pins of the print head (will
require much less the RAM for the TSR, but will print more
slowly):
C:> STAR48E -8 [Return]
(default is the 24 pins)
To install the driver to use a different parallel port:
C:> STAR48E -Lx [Return] (where x is the new port assignment 1, 2 or 3)
(default is LPT1)
To install the driver to not send a form feed after each plot:
C:> STAR48E -P [Return]
(default is a form feed after every plot)
To install the driver for a different interrupt vector (default
is 7B hex):
C:> STAR48E -Vxx [Return] (where xx is the new interrupt number)
To display a list of these options:
C:> STAR48E -H or -? [Return] Prints a help message from star24e.hlp
To install the driver using a combination of the above options:
C:> STAR48E -Oplotdata.plt -v7b -8 This will do the following:
1. Create a plot file 'plotdata.plt' of your drawing on your
default drive for plotting at a later time.
2. The interrupt vector will be 78 (in hex).
3. Will only use 8 pins.
MEMORY REQUIREMENTS FOR DIFFERENT CONFIGURATIONS
RAM Memory required by driver (8" wide plot)
n density Black & White
------------------------------------------------
X x Y
1 = 60 x 180 dpi 19k
2 = 90 x 180 dpi 20k
3 = 120 x 180 dpi 20k
4 = 180 x 180 dpi (default) 22k
5 = 360 x 180 dpi 26k
6 = 360 x 360 dpi 35k
** Note: There are only 2 densities in the vertical direction.
If you do not have AutoCAD and this driver configured for the
same dots per inch, your drawing may be expanded or compressed in
the y-axis.
** Note: Each time you type in the command STAR48E (except for the
special case of the "F" option for plotting binary files),
another copy of the driver software is loaded into memory, using
up to 82k more bytes of RAM. You need to "reboot" the system (to
clear out the any copies of STAR48E.EXE).
CONFIGURING AUTOCAD FOR THE STAR48E SJ-48 DRIVER It is
necessary to reconfigure AutoCAD for an installed ADI printer
plotter driver. You will only need to do this before you want to
use the STAR48E ADI driver for the first time, or when you change the
paper width or the horizontal or the vertical plot densities of
your STAR ADI. Note the present configuration of STAR48E.EXE when
you install it. AutoCAD's printer plotter configuration
densities must be equal for your plots to be correct.
Reconfigure AutoCAD for an installed printer plotter ADI driver <2>.
Be sure that you:
1. Select output format as an Installed ADI driver <2>.
2. Set the maximum horizontal (X) plot size in inches.
These values are 7.99" for the standard size or 13.59"
for the wide carriage printers. The vertical (Y) axis
should be set to your paper size, 10.5 is a good value.
3. Set the density equal to the installed density of the
driver STAR48E.EXE. If AutoCAD's density (dots/inch) is
greater, your drawing will be expanded along that axis
and may be clipped. If the drivers density is greater,
your drawing will be compressed along that axis.
4. The vertical or y-axis has only 2 densities, 180
dots/inch and 360 dpi. For most printer plotting, 180
dpi should be fine.
See the Chapter 8, the printer configuration section of the
Installation & Performance Guide to AutoCAD, Chapter 13 of your
main Reference Manual for AutoCAD details, and your STAR48E Users
guide for printer details.
AutoCAD will now be configured to do a printer plot using the
installed STAR48E ADI driver.
CREATING PRINTER PLOTS WITH THE STAR48E SJ-48 DRIVER
To send plots to the STAR printer from AutoCAD's drawing editor
select Plot then Printer from the AutoCAD menu or type 'prplot'
at the command line. From AutoCAD's Main Menu select Printer
Plot <4>. Make sure your printer is connected, turned on and on
line and hit return when ready. Your plot will be produced on
your STAR 24 pin printer.
** Note: printer plots take a long time to produce, so don't
worry if nothing happens for a while. They can take a very long
time depending on the complexity of the drawing, if you chose
color or if the plot density is high.
OUTPUTTING STAR48E PRINTER FILES FOR DIRECT PRINTING FROM DISK
You may wish to create a file that may be printed multiple times
directly from disk. You can do this with the DOS copy command
without running AutoCAD or STAR48E driver after the file is created.
CAUTION: This option should be used with care. It is possible to
create a file larger than 8 Megabytes if all the settings are at
their maximum. If it is used with some thought it will produce
good results.
Here is an example:
Say you want to produce a 360 x 180 dpi plot of the
site-3d.dwg on 13.59" wide paper.
Install the STAR48E ADI printer driver by typing:
C:> STAR48E -d5 -Osite-3d.eps -W [Return]
Configure AutoCAD as a ADI printer at 360 x 180 dpi, and a
horizontal width of 13.59". Run AutoCAD and printer plot the
site-3d.dwg file. The file site-3d.eps will be created on the
default disk for later printing from the command line.
You can print the file from the DOS command line by typing:
C:> COPY SITE-3D.EPS PRN /B [Return]
In the above example, if you plotted the <E>xtents it would
create a file of 3 Megabytes and would take over an hour to be
produced on a IBM system 30. But if you created a file of the
<D>isplay at 180 x 180 dpi for 7.99" wide paper by typing the
following:
C:> STAR48E -Osite-3d.eps
the file site-3d.eps would be only .3 Megabytes. The creation
time for this file is only 5 minutes on an AT clone running at 10
Mhz.
USE AS A POSTPROCESSOR
The ADI driver STAR48E.EXE can work as a postprocessor, reading
AutoCAD ADI binary files from your disk and sending them directly
to the printer. Printer plot to an ADI binary printer file from
AutoCAD. Then, when the Autodesk product is no longer running, you
may use STAR48E.EXE to plot from the binary file to your STAR printer.
Here's an example:
You want to produce a 360x360 dpi plot of site-3d.dwg on
13.59" wide paper. First you run AutoCAD's configuration program
to select the ADI Printer, plot to binary file, 360x360 dots per
inch, and 13.6" horizontal paper width. Use the PRPLOT command
in AutoCAD. This produces a binary printer plot file called
"site-3d.prp". Next, exit AutoCAD and plot the drawing by
invoking:
STAR48E -Fsite-3d.prp -D6 -W
This will cause STAR48E.EXE to make a plot of the contents of the file
"site-3d.prp" at 360 x 360 dpi on wide paper. When the plot is done,
STAR48E.EXE will vanish from memory (it does not install itself as it
would if you wanted to plot directly from AutoCAD).
**Note: If you added -Osite-3d.epp to the above command line,
the data wouldn't be sent to the printer but a file named
site-3d.epp would be created. See the above section titled
"OUTPUTTING STAR48E PRINTER FILES FOR DIRECT PRINTING FROM DISK"
for details.
NOTES ON OPERATION: AutoCAD TIPS AND HINTS for the STAR48E ADI Driver
1. If you will use the STAR48E ADI driver with every session of
AutoCAD, you may want to place the STAR48E.EXE command in your
AUTOEXEC.BAT file with the correct options set, because you
must install the Printer driver after every reset of your
system.
2. The Printer must be connected, turned on, and on line before
you plot a file using the STAR48E ADI driver.
3. 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 STAR48E driver while the Printer is turned off.
4. If you're using the tractor feed, make sure you've advanced
the paper far enough for the paper bail contact the platen.
5. You will find that high density and/or color plots take much
longer to complete than low density and/or monochrome plots.
