Configuring to use the LPD protocol

Before a user can use the line printer daemon (LPD) protocol to submit jobs to the Ricoh ProcessDirector system, an administrator must do configuration tasks on the Ricoh ProcessDirector system to configure the input devices that receive the jobs, to configure the workflows that the jobs are assigned to, and to define the hosts that can use the LPD protocol to submit jobs to Ricoh ProcessDirector. The administrator might also have to do some configuration tasks on these hosts.
Before you begin this procedure, review the supplied workflows. If you find one that contains some or all the steps that you want to include in your workflow, you can copy it and modify it to meet your needs.

In addition, determine whether you can use one of the LPD input devices that Ricoh ProcessDirector provides or whether the installation requires a customized input device. Ricoh ProcessDirector provides LPD input devices that you can use with only minor modifications or that you can copy to create a customized LPD input device.

To configure to use the LPD protocol:
  1. If you have Linux secondary servers and they are the parent servers for your LPD input devices, stop any LPD daemons or processes on those servers that do not belong to Ricoh ProcessDirector.
    • On SUSE Linux, start YaST, then click System → Network Services to find the LPD services.
    • On Red Hat 6.7 through latest 6.X, choose System → Administration → Services to find the LPD services.
    • On Red Hat 7.1 through latest 7.X, choose Applications → Utilities → Terminal and use this command: systemctl list-units --type service --all.
      To stop an LPD service, use this command: systemctl stop <LPD_service>.

    • Do not uninstall CUPS.
  2. If the parent server of the input device is defined on a Linux computer, update the system setting to specify the hosts that can submit jobs using the LPD protocol.
    If the base product is installed on AIX, you only have to do this step if the parent server of the input device that receives jobs from LPD is a Linux secondary server.
    1. Click the Administration tab.
    2. In the left pane, click System → Settings.
    3. In the Hosts allowed to submit LPD jobs field, type the allowed host names or IP addresses.
      Separate host names and IP addresses with semicolons.

      • You can use wild cards in host names and IP addresses (for example, *.acmeproducts.com or 192.*). A value of * means that all hosts are allowed to submit jobs. Values that contain only numbers, decimal points, and wild cards are compared to IP addresses. Values that contain wild cards and at least one alphabetic character are compared to host names. An empty value means that no hosts are allowed to submit jobs.
      • The default value is *.
      • You cannot submit jobs to LPD input devices from the primary computer.
      • If you experience long wait times or missing jobs, set the LPD host entries to IP addresses or fully qualified host names (such as hostserver.co.acmeproducts.com instead of *.acmeproducts.com).
    4. Click OK.
  3. If the parent server of the input device is defined on a Linux computer, update the system setting to specify the hosts that can submit jobs using the LPD protocol.
    If the base product is installed on AIX, you only have to do this step if the parent server of the input device that receives jobs from LPD is a Linux secondary server.
    1. Click the Administration tab.
    2. In the left pane, click Settings → System.
    3. In the Hosts allowed to submit LPD jobs field, type the allowed host names or IP addresses.
      Separate host names and IP addresses with semicolons.

      • You can use wild cards in host names and IP addresses (for example, *.acmeproducts.com or 192.*). A value of * means that all hosts are allowed to submit jobs. Values that contain only numbers, decimal points, and wild cards are compared to IP addresses. Values that contain wild cards and at least one alphabetic character are compared to host names. An empty value means that no hosts are allowed to submit jobs.
      • The default value is *.
      • You cannot submit jobs to LPD input devices from the primary computer.
      • If you experience long wait times or missing jobs, set the LPD host entries to IP addresses or fully qualified host names (such as hostserver.co.acmeproducts.com instead of *.acmeproducts.com).
    4. Click SAVE.
  4. If the parent server of the input device is defined on an AIX computer, make sure the computer is configured to accept jobs submitted using the LPD protocol.
    1. On the AIX computer, log in as the root user.
    2. Make sure that the LPD daemon is installed and running.
      To start the LPD daemon using the System Management Interface Tool (SMIT), click Print Spooling → AIX Print Spooling → Manage Print Server → Start the Print Server Subsystem (LPD daemon).
    3. Add the host name or IP address of the systems that you want to allow to submit jobs to the /etc/hosts.lpd file:
      1. In SMIT, click Print Spooling → AIX Print Spooling → Manage Print Server → Add Print Access for a Remote Client.
      2. In the Name of REMOTE CLIENT field, type the host name or IP address of the system that you want to allow to send jobs to the Ricoh ProcessDirector server.

        • If you are not using Domain Name Services (DNS), you must fully qualify the host name. For example: mathomhouse.micheldelving.org.
        • You cannot submit jobs to LPD input devices from the primary computer.
      3. Click Enter.
  5. On each system that you authorized to submit LPD jobs, determine if the print command lets you specify a server name. If it does not, do one of the following steps to create a print queue on the system to send jobs to the LPD input device.

    • The LPR client that is supplied with the base operating system in some versions of Windows and that is available as an optional feature of other versions lets you specify a server name. If you use this LPR client or an equivalent, you do not have to create a print queue on Windows.
  6. To create a print queue on SLES 12.0:
    1. Log in as the root user.
    2. Start YaST.
    3. Click Hardware → Printer. With Printer Configurations highlighted, click Add. Click Connection Wizard, and then select Line Printer Daemon (LPD) Protocol.
    4. In the IP Address or Host Name field, type the host name or IP address of the system where the LPD input device is defined.
    5. Type the name of the LPD input device in the Queue Name field, and click OK.
    6. In the Set Arbitrary Name field, type the name of the LPD input device. This name must be unique on this Linux system. Although LPD input device names are case-sensitive, Linux does not allow you to define multiple LPD input device names that are alike except for case. For example, you cannot define one LPD input device called HotFolderLPD and another called hotfolderlpd.
    7. Click OK.
  7. To create a print queue on Red Hat 6.7 through latest 6.X:
    1. Log in to the operating system as the root user.
    2. From the Gnome Desktop, click Applications → System Tools → Terminal.
    3. In the terminal window, type system-config-printer.
    4. Select Printer on the New drop-down menu.
    5. Click Network Printer and select LPD/LPR Host or Printer.
    6. In the Host field, type the host name or IP address of the system where the LPD input device is defined.
    7. Type the name of the LPD input device in the Queue field, and then click Forward.
    8. In the New Printer window, click Forward.
    9. Click Forward again.
    10. Type a name for the LPD input device in the Printer Name field.
    11. Click Apply.
  8. To create a print queue on Red Hat 7.1 through latest 7.X:
    1. Log in to the operating system as the root user.
    2. From the Gnome Desktop, click Applications → Utilities → Terminal.
    3. In the terminal window, type system-config-printer.
    4. Select Printer on the Add drop-down menu.
    5. Click Network Printer and select LPD/LPR Host or Printer.
    6. In the Host field, type the host name or IP address of the system where the LPD input device is defined.
    7. Type the name of the LPD input device in the Queue field, and then click Forward.
    8. In the New Printer window, click Forward.
    9. Click Forward again.
    10. Type a name for the LPD input device in the Printer Name field.
    11. Click Apply.
  9. To create a print queue on AIX:
    1. Log in as the root user.
    2. Start SMIT.
    3. Click Print Spooling → AIX Print Spooling → Add a Print Queue → Remote → Standard processing.
    4. In the Name of QUEUE to add field, type the name of the LPD input device.
    5. In the HOSTNAME of remote server field, type the host name or IP address of the system where the LPD input device is defined.
    6. In the Name of QUEUE on remote server field, type the name of the LPD input device.
  10. On the Ricoh ProcessDirector system, copy and modify a workflow that contains the processing steps that you want the jobs that are submitted using the LPD protocol to follow.

    To copy and modify one or more workflows:

    1. Click the Workflow tab.
    2. In the Workflow Objects portlet, click the Workflows tab.
    3. Select the workflow that you want to copy, and click Copy workflow (Copy workflow icon).
    4. Right-click the workflow that you want to copy, and click Copy.
    5. Type a name for the new workflow, and click OK.
    6. Name the copy of the workflow, fill in or edit other values that you need, and click Continue.
    7. Select each step and click Properties (Properties icon) on the Workflow Editor portlet. Modify the properties as necessary.
      Remove ${Job.InputFile} from the Job name property in the SetJobPropsFromTextFile step.
    8. Right-click each step and select Properties. Modify the properties as necessary.
      Remove ${Job.InputFile} from the Job name property in the SetJobPropsFromTextFile step.
    9. If you have the AFP Support feature installed and the AFP resources (such as fonts, overlays, and page segments) required by the jobs that are processed through this workflow are not going to be sent inline with the input file, make sure that those resources are available to the Ricoh ProcessDirector system. We recommend that you move these resources to /aiw/aiw1/resources or /usr/lpp/psf/reslib, so that they are available to all the components of Ricoh ProcessDirector. If you cannot use those directories, you can set the AFP resource path property on one of the steps in the workflow to refer to the directory or directories that hold the resources.

      • The AFP resource path can be set as a default job property on various step templates, including EnableRepositioning, PrintJobs, and ConvertLineDataJobIntoAFP. You only need to set the value on one of the steps; the others inherit the value.
    10. When you are finished updating the workflow, click Save workflow (Save workflow icon).
    11. To use the workflow, go to the Workflow Objects portlet. Select the workflow and click Enable workflow (Enable workflow icon).
    12. To use the workflow, save and enable it by changing Image, the Save & Enable/Disable switch, to the On position.
    13. Repeat these steps if you want to create additional workflows.
  11. On the Ricoh ProcessDirector system, configure an input device so that it assigns the correct workflow or workflows for the input files that it receives. We recommend that you copy and rename one of the supplied LPD input devices, then verify or update the settings described below.
    1. Click the Administration tab.
    2. In the left pane, click Devices → Input Devices.
    3. Right-click the input device that you want to copy and select Copy.

      • The new input device is the same type as the copied input device. For example, you cannot create a new LPD input device by copying a hot folder.
    4. In the left pane, click Show all tabs to display all the properties for this input device.
    5. Verify or update the values for these properties:

      Input device name

      Make sure that the input device name does not include any spaces. The LPR client cannot process names with spaces.

      It is best to limit the input device name to 8 characters. Depending on the print command that you use, you might have to create a print queue on the sending system with the same name as the input device. Some systems truncate print queue names to 8 characters.

      Folder location

      The directory on the primary computer that receives jobs from authorized hosts. Make sure that the file system is set up so that the directory you list here is large enough to handle the amount of data that the LPR client sends without filling the file system.

      Staging location

      The directory that Ricoh ProcessDirector moves input files to before they are submitted as jobs. Make sure that the file system is set up so that the directory you list here is large enough to handle the amount of data that the LPR client sends without filling the file system. Remember that there might be two copies of an input file in the system at any time, one in the Folder location directory and one in the Staging location directory.

      Parent server

      The Ricoh ProcessDirector server where the files will be received; for example, a submitter would specify this server name on the lpr or lprafp command. The server specified here must be configured to accept jobs over the LPD protocol.
    6. To assign workflows to jobs, with either single or multiple input files:

      • Input devices with a Linux parent server cannot create a parent job with multiple children. Instead, one parent job and one child job are created for each input file.
      1. Set the Submit step property to SubmitInputFiles and the Workflow property to ParentNoPrint.
      2. Determine how you want the input device to assign the workflow for each single job or child job. You can select one of these:
        • Set the Child workflow initialization step property to SetJobTypeFromRules and use the Child workflow parsing rules property to specify the name of the control file that can set the workflow from a value of an option of the print command.
          Ricoh ProcessDirector provides two sample control files that are used to set the workflow. The sample control files, called receive_lpd_jobtype.cfg and receive_lpd_pdf_jobtype.cfg, are installed in the /aiw/aiw1/samples/rules/ directory. You can copy one of the files to the /aiw/aiw1/control_files/rules/ directory and modify it to meet your needs, then update the value of the Child workflow parsing rules property to point to your file.
        • Set the Child workflow initialization step property to SetJobTypeFromFileName and use the Child workflow pattern property to specify the string that Ricoh ProcessDirector should look for in the input file name and use as the workflow name. If you use this method, you must make sure that a workflow with the corresponding name exists.
  12. If the control file that you created in the previous step sets job scheduling properties such as Media or Job size based on the values of options of the print command, make sure that the corresponding scheduling properties are set on the target printers in Ricoh ProcessDirector. If the scheduling properties do not match, the jobs are not automatically scheduled to those printers.
  13. Make sure that the LPD input devices are connected and enabled.

    • The LPD input device does not return status information in response to the lpq command.
  14. From a host system that you authorized, submit some test jobs. If errors occur, correct the errors that messages from the host system or Ricoh ProcessDirector identify.
