_FilePrint of an "in use" Word document . How to file unlock?

[Tippex]

Sometimes when _FilePrint is used to print a Word document which has been locked for some reason (eg. it has just been copied from somewhere) a prompt appears asking the User if a read-only copy may be opened [for the purpose of printing it].

I was wondering if there was some way of using _FilePrint to always take a read-only copy to use for printing (so that the pop-up window isn't displayed or has to have additional coding to deal with)?

Better still, is there any function (eg. UDF) that can be used to [attempt to] force a file to be unlocked so that Windows doesn't consider it to be "in use" by some process please?

AutoIt comes with a Word UDF which should handle this.
