NAME
       escputil - maintain Epson Stylus inkjet printers

SYNOPSIS
       escputil  [  -P printer | -r device ] [ -m model ] [ -S ] [ -C ] [ -p ] [ -u ] [ -c | -n |
       -a | -i | -d | -o | -s | -l | -M | -h ] [ -q ]

DESCRIPTION
       escputil is a command line utility to perform various maintenance tasks	on  Epson  Stylus
       inkjet printers.  These tasks include head alignment, head cleaning, nozzle check, printer
       identification, and retrieval of ink level from the printer.

OPTIONS
       escputil accepts the following options:

       -P, --printer-name=printer
	      Specify the name of the printer to operate on.  The default is the  default  system
	      printer.

       -r, --raw-device=device
	      Specify  the  name  of  the device to write to directly rather than going through a
	      printer queue. You must use this (rather than specifying a printer) when retrieving
	      ink  levels  or  identifying  the printer, or if you wish to perform head alignment
	      without specifying the printer model.

       -m, --model=model
	      Specify the precise printer model for head alignment.

       -u, --new
	      The printer is a new printer (Stylus Color 740 or newer).

       -S, --short-name
	      Print the short name of the printer with --identify.

       -C, --choices
	      Specify the number of pattern choices for alignment.

       -p, --patterns
	      Specify the number of sets of patterns for alignment.

       -c, --clean-head
	      Clean the print head.  This can also be performed from the printer front panel.

       -n, --nozzle-check
	      Print a nozzle test pattern.  Dirty or clogged nozzles will show	as  gaps  in  the
	      pattern.	If you see any gaps, you should run a head cleaning pass or two.

       -a, --align-head
	      Align  the  print  head.	 CAUTION:  Misuse of this option may result in poor print
	      quality and/or damage to the printer.  You must either specify  the  printer  model
	      with  the  -m option, or use the raw printer device to allow escputil to detect the
	      printer model.

       -i, --ink-level
	      Obtain the ink level from the printer.  This requires read/write access to the  raw
	      printer device.

       -d, --identify
	      Query  the printer for make and model information.  This requires read/write access
	      to the raw printer device.

       -o, --align-color
	      Align the color print head (used by Stylus Color 480 and 580 only).  CAUTION:  Mis-
	      use of this option may result in poor print quality and/or damage to the printer.

       -s, --status
	      Retrieve printer status.

       -l, --license
	      Display the license/warranty terms of this program.

       -M, --list-models
	      List the supported printer models.

       -h, --help
	      Display a list of all command line options.

       -q, --quiet
	      Suppress the banner.

BUGS
       USB-connected  printers	sometimes fail to identify or return ink levels.  You may have to
       repeat the command.  This is probably a timing issue  in  escputil,  not  a  flaw  in  the
       printer.

       Anything  requiring bidirectional communication with the printer (identify, ink levels, or
       head alignment without specifying the printer model) requires  read/write  access  to  the
       printer port (for example /dev/lp0).  This may require these operations to be performed as
       root.  In addition, kernel support is required for bidirectional communication.	For Linux
       version 2.2, CONFIG_PRINTER_READBACK should be enabled; this is called CONFIG_PARPORT_1284
       on 2.4 and later kernels.

       If the printer is performing self-test or head cleaning on power up, the identify and  ink
       level commands will time out, although the printer successfully receives the command.  The
       command will need to be reissued when the printer is quiescent.
