Abstract: In a conventional printing apparatus with a plurality of paper feed ports, since a paper type limits the paper feed port usable for paper feed, a user must know in advance a paper feed port to set a paper sheet. This arrangement is not user-friendly. A printing apparatus according to the present invention, however, holds table information indicating the correspondence between paper types and paper feed ports usable for paper feed. When a paper type is designated together with input print data, information on a paper feed port usable for paper feed is acquired from the table information. A message is displayed to prompt the user to set a paper sheet on the paper feed port usable for paper feed so that the user can set an appropriate paper sheet.
