Also remember that the 'knowledge' of the design system printer is made part of the report frx in the first row fields EXPR, TAG, and TAG2. This can be most trouble some e.g. the user attempts a network printer selection and the app insist on printing thru lpt1 local because thats the info from the development system. You should consider blanking these three fields prior to shipment with the exception of items in EXPR that are necessary like ORIENTATION= for portrat/landscape etc.
Hope this helps some
