when you say, "irrespective of doc source", do you mean where the "doc" is located?
is it all types of "doc", i.e. "Word" documents, Spreadsheets, photos, plain txt files?
If it is just "Word" .doc files does it happen with old .doc files you may have, or just new ones? Try saving a document as a .rtf file, then opening it in "Wordpad" and see if that prints.
If it's just new ones then, clutching at straws, it might be a faulty template. Search for and delete or rename, "normal.dot", (With "Word" closed). You may have to make hidden files visible. On restarting "Word" a new "normal.dot" will be generated. Try a creating a new document and see if that works.
Sorry if none of this helps?
