Greetings,
You have nothing to worry about. The buffer is overwritten regularly as more documents are printed. Wireless information is stored, but in an encrypted format. Resetting the printer before donation is enough to erase that. Also when another connection is made, it would be overwritten. Your printer's buffer does not have a retention or recall feature. See this blurb I wrote previously about such items.
