Ok, now understand what you want to achieve. I guess you
want to set the 
printer name while creating the menu items.

This way is not possible for your scenario. A menu item
cannot store a 
property value.

This is the way to go for your scenario.

Your protocol handler implements the XDispatch interface.
The 
OpenOffice.org menu uses this interface to call your
implementation.

dispatch( const com::sun::star::util::URL aURL, Sequence<

beans::PropertyValue > aArgs )

As you can see the dispatch function has two arguments (aURL
and aArgs). 
The arguments inside your command URL are part of aURL. It's
a structure 
containing several members which describe parts of the URL.
Your 
arguments can be found inside aURL.Arguments. You have to
parse the 
string. For more information see the description of 
com.sun.star.util.URL IDL file.

No.
