Acad Multiple Plotters and ADI plot drivers

To get from AutoCAD's "printing to a port" to NT named resources with multiple
plotters do these steps:

1)  create a batch file named "C:\plot.bat" with the following commands:
    c:
    cd\
    set printto=
    if x%2==x1 set printto=\\Machine1\Printer1
    if x%2==x2 set printto=\\Machine2\Printer2
    if x%2==x3 set printto=\\Machine3\Printer3
    if x%2==x4 set printto=\\Machine4\Printer4
    if x%printto%==x goto error

    copy /b %1 %printto%
    del %1
    goto end

    :error
    echo
    echo Printer driver %2 is not valid
    pause

    :end

2)  Start Autocad and go to Preferences/misc/plot spooling and enter
    C:\plot.bat %s %p

3)  Go into Autocad's Configure option pick #7 "Configure Operating
    Parameters" and pick #3 "Default Plot File" enter the name "autospool"

4)  In autocads configure display and write down all the configured
    plotters and their number (ie 1,2,3,ect) These are the numbers used in
    the plot.bat file (ie x1=plotter autocad config shows as 1)

5)  Still in the configure operating parameters pick #4 "Plot Spooler Dir"
    and enter "C:\" then exit configure

When you plot, select the plotter you want to send to, check plot to file,
make sure the file name is autospool and click OK. This will create a plot
file, automatically copy the file to the printer and delete the file when
done. It works great!
