Issue
You want to turn off the plot warning that is displayed when the printer is not configured in the system.
Solution
To prevent the plot warning from being displayed, you can create a DWORD-value key in the Windows Registry named PLQUIET and set its value to 1. Follow these steps:
Click Start menu (Windows) > Run.
In the Run dialog box, enter regedit
In the Registry Editor, navigate to the following key:
HKEY_CURRENT_USER\Software\Autodesk\AutoCAD LT\R14\ACADLT-7001:409\Profiles\<<Unnamed Profile>>\General
Note: The values "R14" and "ACADLT-7001:409" will vary according to the product version and language. This path is for AutoCAD® LT 2009, English version.
Create a new subkey named "PLQUIET" under the General key by clicking Edit menu > New > DWORD Value.
Double-click the PLQUIET key.
Enter 1 in the Value Data box and then click OK.
Close the Registry Editor.
