ippserver - a simple ipp server


ippserver [ -2 ] [ -C config-directory ] [ -K keypath ] [ -M manufacturer ] [ -P ] [ -a attributes-file ] [ -c command ] [ -d spool-directory ] [ -f type/subtype[,...] ] [ -h ] [ -i iconfile.png ] [ -k ] [ -l location ] [ -m model ] [ -n hostname ] [ -p port ] [ -r subtype ] [ -s speed[,color-speed] ] [ -u username:password ] [ -v[vvv] ] service name


ippserver is a simple Internet Printing Protocol (IPP) server conforming to the IPP Everywhere and IPP Shared Infrastructure Extensions (INFRA) specifications. It can be used as a standalone print server and/or a very basic infrastructure server between standard IPP clients and IPP proxies conforming to the INFRA specification.


The following options are recognized by ippserver:
-2 Specifies that the printer supports two-sided printing.
-C config-directory
Specifies the location of a directory containing files that define the configuration of the server and the service instances that are available. See the section titled "CONFIGURATION DIRECTORIES" below.
-K keypath
Specifies the location of TLS certificates and private keys.
-M manufacturer
Specifies the manufacturer for the printer.
-P Specifies that the printer will require a PIN ("job-password") for submitted print jobs.
-a attributes-file
Specifies a file containing attribute definitions for the printer.
-c command
Specifies a command that is used to process job files.
-d spool-directory
Specifies the directory that will hold the print files. The default is a directory under the user’s current temporary directory.
-f type/subtype,[...]
Specifies the list of supported MIME media types.
-h Shows program help.
-i iconfile.png
Specifies a PNG file for the printer icon.
-k Keeps the print documents in the spool directory rather than deleting them.
-l location
Specifies the "printer-location" string for the printer.
-m model
Specifies the model name of the printer.
-n hostname
Specifies the hostname that is reported by the server. The default is the name returned by the hostname(1) command.
-p port Specifies the port number to listen on. The default is a user-specific number from 8000 to 8999.
-r subtype
Specifies the Bonjour subtype to advertise for the printer. The default subtype is "_print".
-s speed[,color-speed]
Specifies the printer speed in pages-per-minute.
-u username:password
Specifies the username and password for the IPP proxy.
-v[vvv] Be (very) verbose when logging activity to the standard output.


The ippserver program returns 1 if it is unable to process the command-line arguments. Otherwise ippserver will run continuously until terminated.


Run ippserver with a service name of My Cool Printer:

ippserver "My Cool Printer"
Specify a proxy username of "foo" and password of "bar":

ippserver -u foo:bar "My Cool Printer"


When the -C option is specified, ippserver reads a series of configuration files from the specified directory to configure the server and services supported by the server.


The system.conf configuration file specifies settings that apply to all services. Each line consists of a directive followed by its value(s). Comments start with the # character and continue to the end of the line. The following directives are supported:
DataDirectory directory
Specifies the location of server data files.
DefaultPrinter name
Specifies the default print service name.
Encryption {Always|IfRequested|Never|Required}
Specifies when to use TLS encryption for client connections. "Always" means that all connections are encrypted when established (HTTPS). "IfRequested" means that connections are encrypted when an upgrade is requested by the client. "Never" means that encryption is not allowed or supported. "Required" means that all connections are encrypted, either when established (HTTPS) or immediately thereafter using HTTP Upgrade.
KeepFiles {No|Yes}
Specifies whether job data files are retained after processing.
Listen address[:port]
Listens for client connections on the specified address and port. If the address is "*" the server will listen for connections on all network interfaces. If the port is omitted, a port between 8000 and 8999 will be used.
LogFile path
Specifies a log file to use. The path "stderr" causes all log messages to be directed to the standard error file descriptor.
LogLevel {Debug|Info|Error}
Specifies the verbosity of logged messages. "Debug" is the most verbose level, logging all messages. "Info" provides basic progress and status messages. "Error" provides only error messages.
MaxCompletedJobs number
Specifies the maximum number of completed jobs that are retained for job history. The value 0 specifies there is no limit. Note: ippserver currently removes completed jobs from the job history after 60 seconds.
MaxJobs number
Specifies the maximum number of pending and active jobs that can be queued at any given time. The value 0 specifies there is no limit.
SpoolDirectory path
Specifies the location of print job spool files.


Each 2D print service is configured by a print/name.conf configuration file, where "name" is the name of the service in the printer URI, e.g., "ipps://hostname/ipp/print/name". Each 3D print service is configured by a print3d/name.conf configuration file, where "name" is the name of the service in the printer URI, e.g., "ipps://hostname/ipp/print3d/name". Each line consists of a directive followed by its value(s). Comments start with the # character and continue to the end of the line. The following directives are supported:
Attr value-tag name value(s)
Specifies a Printer Description attribute. The format is further defined in ipptoolfile(7).
AuthType {None|Basic}
Specifies the type of authentication to require. "None" specifies that no authentication is required. "Basic" specifies that HTTP Basic authentication (username + password) is required.
Command command
Specifies the command to run when processing jobs. The ipptransform(1) command can be used for many printers.
DeviceURI uri
Specifies the printer’s device URI.
Make manufacturer
Specifies the manufacturer name for the printer.
Model model
Specifies the model for the printer.
ProxyUser user
Specifies the name of the proxy user for the printer.


The icon for each 2D print service is stored in the print/name.png file. Similarly, the icon for each 3D print service is stored in the print3d/name.png file.
