Control Object provides the application with a set of property, method and event for each 

device class.    CO is a standard Active (OLE 32 bit) control and is not visible at the time of 
execution.    As a rule, this driver uses OPOS standard CO.    (OPOS standard CO is installed 
automatically at the installation of this driver.)
