NAME
     escputil - maintain Epson Stylus inkjet printers

SYNOPSIS
     escputil [-P printer  -r device] [-c  -n | -a  -i] [-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.
             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 speci-
             fying the printer model.

     -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  noz-
             zles  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 util-
             ity  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 dev-
             ice.

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

     -u      The printer is connected via USB.

     -h, --help
             Display a list of all commandline options.

     -q, --quiet
             Suppress the banner.

     -m <model>
             Specify the precise printer model  for  head  align-
             ment.

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.

     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 quies-
     cent.
