LPD Input

LPD (Line Printer Daemon) Input tasks retrieve data in the form of print files sent from remote computers using the LPD/LPR protocol. The PlanetPress Workflow LPD server starts automatically when a configuration that includes at least one active LPD Input task is started.

To prevent conflicts between competing LPD servers, you must not run any other LPD server than the PlanetPress Workflow LPD server on PlanetPress Workflow workstation.

LPD Input tasks are configured primarily through user options (see LPD Input plugin preferences). The only LDP information you enter in each LPD task is the queue name.

Input

This task does not poll an input, it sits there and waits for a job file to be sent through the LPR port.

Processing

When the job is received through LPR, it is saved as a job file. No further processing is done on the file.

Output

The task outputs the job file as is, with no evaluation or modification.

Task properties

General Tab
  • LPD queue names: Enter the queue name (or names, one per line) specified in the printer queue on the remote computer or computers.
  • Allow empty queue names: Check this option to accept LPR jobs that don't specify a queue name.

  • Create PDF (With Metadata): Select to output a PDF. This will only work with PostScript input.

    • Optimize Resulting PDF: The resulting PDF is optimized for size and caching options are enabled. This reduces the size of the PDFs (depending on some factors), but may take more time to output the PDF.
"Other" Tab
  • Job Information group
    • Information elements: Indicates what Job Info variables are automatically created by the input task.
    • Add lines before first data page: Using the arrows keys you can add any job information directly at the beginning of your data file.
  • Backup input files: Check this to save a copy of each data file that is captured by your input. These files are saved in the PlanetPress Workflow Tools working folders under the "Backup" folder.
    To navigate quickly to the Workflow working folders, press the keyboard shortcut CTRL+ALT+Shift+F4 from within the Workflow configuration tool.
    The number of days to keep backups of jobs processed by input tasks is set per process; see Process properties.
  • Backup filename: Enter the file name that you wish the input data file backup to be saved under.
  • Delete Existing Metadata: Check to remove any Metadata from memory. This option is disabled on initial input tasks, and is checked by default on secondary input tasks.
Job Information definitions
  • %1 - User name: Contains the user name of the user who sent the job to the printer, or the user for which a software sending the job was logged in under.
  • %2 - Host computer: Contains the name of the computer from which the job was sent.
  • %3 - Job name: Contains the name of the job as specified by the software that sent the job.
  • %4 - Source file name: Contains the name of the job file as specified by the software that sent the job.
  • %5 - Sender's IP address: Contains the IP address from which the job was sent.

  • %6 - 6 Queue name: The name of the queue from which the job was captured. It will be empty if the queue name was empty.

On Error Tab

For a description of the options on the On Error tab see Using the On Error tab.

Miscellaneous Tab

The Miscellaneous tab is common to all tasks.

It contains a text area (Task comments) that lets you write comments about the task. These comments are saved when the dialog is closed with the OK button and are displayed in The Task Comments Pane.

Check the option Use as step description to display the text next to the icon of the plugin in the Process area.

The tab also provides an option to highlight the task in The Process area with the default color, set in the Preferences (see Colors), or the color selected or defined under Highlight color on this tab.
To revert the selected highlight color to the default color, open this tab, turn the Highlight option off and close the dialog with the OK button; then turn highlighting back on.
Highlighting can also be turned on and off via the task's contextual menu and with the Highlight button on the View ribbon.
