 +Some programs use ANSI escape sequences to print data; this was originally used in the days when serial terminals were common, and a terminal might have a printer directly attached to it.  Any sequence starting with ''<esc>[5i'' and ending with ''<esc>\'' would cause the data between the two escape sequences to be printed.  ''screen'' supports this behavior in two ways: if the display terminal has the ''po'' and ''pf'' termcap entries (indicating that it understands printing escapes), ''screen'' will pass any print requests through to the display terminal.  Alternately, you can use the ''[[commands:printcmd]]'' command to define a program to which ''screen'' will send any print jobs.
