Command-line parameters: 

/product=<productName> or a part of the product name 
/driver=<drivername> or a part of the driver name 
/monitor=<printmonitorname> or a part of the monitor name 
/auto=true|false (automatic uninstallation, no UI is displayed, but the UI is displayed if the "normal" method was not worked) 

Because this tool was written for the eDocPrintPro the command-line parameters have the following default values: 

/driver=eDocPrintPro 
/monitor=eDocPortMonitor 
/product=eDocPrintPro 
/auto=false 

This set of parameters will enumerate only edocprintpro resources: 
-printers, drivers, ports, monitors, applications 

But you can test the application with other parameters: 

/driver=none 
/monitor=none 
/product=none 
/auto=false 

In this case all applications, printers, drivers monitors and ports will be enumerated.

Sample to uninstall the application e.g. "QiScan": 

eDocUninstall.exe /product=QiScan /driver=none /monitor=none
