    longDescription = ''
      p910nd is a small printer daemon intended for diskless platforms that
      does not spool to disk but passes the job directly to the printer.
      Normally a lpr daemon on a spooling host connects to it with a TCP
      connection on port 910n (where n=0, 1, or 2 for lp0, 1 and 2
      respectively). p910nd is particularly useful for diskless platforms.
      Common Unix Printing System (CUPS) supports this protocol, it's called
      the AppSocket protocol and has the scheme socket://. LPRng also supports
      this protocol and the syntax is lp=remotehost%9100 in /etc/printcap.
