Printing on the AS/400 has many subtopics, so we only cover basic knowledge and specialized, hard to find information in here. See Weblinks below for additional documentation.
Surprisingly, the AS/400 is no different with common platforms when it comes to principles of printing. There are printer devices the application programs can talk to, and spooling mechanisms to provide background handling of shoveling data to the usually slower printers. Maybe that's because this basic principle has already been established in the early years of mainframe computing, when HASP was still separate from OS/360.[1] Maybe, common platforms inherited ideas from there, or came up with similar concepts. There are just a limited number of ways to provide for asynchronous printing.
