The "print" context menu item is not suitable for printing from Flex applications. It is more appropriate for Flash applications created with Flash Professional. You should implement your own printing functionality.

If you wish to print from the context menu then you could create a Custom "context menu" in flex via the ContextMenu and ContextMenuItem classes. See also Working with Menus in the AS3 Developer's Guide.

To change the context menu:

var my_cm:ContextMenu = new ContextMenu();
my_cm.hideBuiltInItems();
var printItem:ContextMenuItem = new ContextMenuItem("Print proper image");
my_cm.customItems.push(printItem);
this.contextMenu = my_cm;

Don't forget that you can't use the "Print" caption, because it is reserved for the internal print function (see Restrictions).
