dcmprscu - Print spooler for presentation state viewer


dcmprscu [options] [dcmfile-in...]


The dcmprscu utility implements the DICOM Basic Grayscale Print Management Service Class
as SCU. It also supports the optional Basic Annotation Box and Presentation LUT SOP
Classes. The utility is intended for use within the DICOMscope viewer.

The dcmprscu utility takes complete print jobs consisting of a Stored Print object and one
or more Hardcopy Grayscale objects and spools them to the printer. No attempt is made to
check whether the attributes defined in the Stored Print object are supported by the Print
SCP. However, the print spooler will not attempt to use the optional Annotation or
Presentation LUT services if they are not successfully negotiated with the Print SCP.

The dcmprscu utility reads the characteristics of the printer to communicate with from the
configuration file. Depending on the printer's support for Presentation LUT, any
Presentation LUT present in the print job will be rendered into the hardcopy images before
they are spooled to the printer if necessary. If the printer does not support image
transmission with 12 bits/pixel (as per the configuration file), the grayscale hardcopy
images are down-sampled to 8 bits/pixel before transmission to the printer.

The dcmprscu utility can be run either in 'printer mode', in which case the file name of a
Stored Print object must be passed, or in 'spool mode', in which case commands are read
periodically from a spool directory.


dcmfile-in stored print file(s) to be spooled


general options

-ll --log-level [l]evel: string constant
(fatal, error, warn, info, debug, trace)
use level l for the logger

-lc --log-config [f]ilename: string

spooler options (only with --spool)
--sleep [d]elay: integer (default: 1)
sleep d seconds between spooler checks

basic film session options (not with --spool):
--copies [v]alue: integer (1..100, default: 1)
set number of copies to v

--medium-type [v]alue: string
set medium type to v

--destination [v]alue: string
set film destination to v

--label [v]alue: string
set film session label to v

--priority [v]alue: string
set print priority to v

--owner [v]alue: string
set film session owner ID to v


The level of logging output of the various command line tools and underlying libraries can
be specified by the user. By default, only errors and warnings are written to the standard
error stream. Using option --verbose also informational messages like processing details
are reported. Option --debug can be used to get more details on the internal activity,
e.g. for debugging purposes. Other logging levels can be selected using option --log-
level. In --quiet mode only fatal errors are reported. In such very severe error events,
the application will usually terminate. For more details on the different logging levels,
see documentation of module 'oflog'.

In case the logging output should be written to file (optionally with logfile rotation),
to syslog (Unix) or the event log (Windows) option --log-config can be used. This
configuration file also allows for directing only certain messages to a particular output
stream and for filtering certain messages based on the module or application where they
are generated. An example configuration file is provided in <etcdir>/logger.cfg.


All command line tools use the following notation for parameters: square brackets enclose
optional values (0-1), three trailing dots indicate that multiple values are allowed
(1-n), a combination of both means 0 to n values.

Command line options are distinguished from parameters by a leading '+' or '-' sign,
respectively. Usually, order and position of command line options are arbitrary (i.e. they
can appear anywhere). However, if options are mutually exclusive the rightmost appearance
is used. This behavior conforms to the standard evaluation rules of common Unix shells.

In addition, one or more command files can be specified using an '@' sign as a prefix to
the filename (e.g. @command.txt). Such a command argument is replaced by the content of
the corresponding text file (multiple whitespaces are treated as a single separator unless
they appear between two quotation marks) prior to any further evaluation. Please note that
a command file cannot contain another command file. This simple but effective approach
allows one to summarize common combinations of options/parameters and avoids longish and
confusing command lines (an example is provided in file <datadir>/dumppat.txt).


The dcmprscu utility will attempt to load DICOM data dictionaries specified in the
DCMDICTPATH environment variable. By default, i.e. if the DCMDICTPATH environment variable
is not set, the file <datadir>/dicom.dic will be loaded unless the dictionary is built
into the application (default for Windows).

The default behavior should be preferred and the DCMDICTPATH environment variable only
used when alternative data dictionaries are required. The DCMDICTPATH environment variable
has the same format as the Unix shell PATH variable in that a colon (':') separates
entries. On Windows systems, a semicolon (';') is used as a separator. The data dictionary
code will attempt to load each file specified in the DCMDICTPATH environment variable. It
is an error if no data dictionary can be loaded.
