I use OpenOffice.org all the time. In my opinion it is far better than MS office, if not for the operation and options then for the price. Free!! Not to mention you can convert from many different formats that MS office can not read, let alone convert. Oh, and one more thing, far less of a chance for a virus with openoffice than MS office.
As for printing, that all works through your operating system and computer system it self. Lexmark? isn't that your printer? and/or printer driver?
