Print filters convert the content type of a file to a content type that is acceptable to the destination printer. The file contents tells the LP print service the type of file contents that can be printed directly, without filtering. To print without filtering, the necessary fonts must also be available in the printer. (You must set up and use filtering for other types of files.)
You can specify the file contents for a printer by using the lpadmin -I command or Printer Manager.
In Printer Manager, you can select a specific file contents type from a menu. Not all available file contents types are listed on the menu. You must use the lpadmin command to specify file content types that are not included on the Printer Manager menu.
