ARX如何得到当前CAD打印设备列表及其他打印设置内容

/*
To query the all the available plot configurations you should use plotDeviceList()
method of AcDbPlotSettingsValidator class.
And to get the list of available media names for a given plot configuration,
use canonicalMediaNameList() method AcDbPlotSettingsValidator class.
But note the media names may not be same as listed in the Plot dialog.
So to get the media name as listed in the drop down list,
supply the media name to the function getLocaleMediaName().

The sample code below lists the available plot configurations and asks the user to select one.
After user enters his choice, all the available media are listed and user can select one to set it current.
Please use ObjectARX Wizard to create an ARX project and call the function () from a user defined function.
Make sure that you are *not* registering the command using ACRX_CMD_SESSION.
