FOOMATIC-GETPJLOPTIONS(8)				      System Manager's Manual					 FOOMATIC-GETPJLOPTIONS(8)

NAME

       foomatic-getpjloptions - <put a short description here>

SYNOPSIS

       foomatic-getpjloptions device

       foomatic-getpjloptions hostname port

DESCRIPTION

       foomatic-getpjloptions  Sends  a  set of PJL commands and reads back the PJL options and status from a printer over a network connection or
       device bidirectional interface such as parallel, USB, serial.  printers to standard output. The output can be piped into foomatic-addpjlop-
       tions to add options to the database.

   Options
       device	 The interface to which a local printer is connected, e.g. /dev/lp0, /dev/usb/lp0, /dev/tty00, etc.  For a parallel port, you must
		 have bidirectional support enabled at the BIOS level and the parallel port driver must support  the  bidirectional  mode.   Check
		 your parallel port BIOS settings for  EPP/bi-directional mode.

       hostname  Host name or IP address of a network printer (HP JetDirect, DLINK, etc.).

       port	 Port  on  which  your	network printer listens for socket (Appsocket) connections.  Most common ports are 9100 (JetDirect), 10000
		 (DLINK).  Usually you can configure the port via a configuration interface.

EXIT STATUS

       foomatic-getpjloptions returns ???

AUTHOR

       Manfred Wassmann <manolo@NCC-1701.B.Shuttle.de> for the foomatic project using output from the associated binary.  Modified by Patrick Pow-
       ell <papowell at lprng.com> to provide betters support for network printers, error messages, and remove CR and FF from output.

WARNINGS

       Uni-directional	protocols  as remote LPD are not supported as no status is returned.  Some network print servers which attach to a printer
       parallel port do not support bidirectional mode.
