14.4 Renderer Issues

14.4.1 Secure Renderer Registration Fails

On applying SUSE SLE security updates, registration to a secure renderer fails. To resolve this issue, do the following:

  1. On the appliance, execute the following commands:

    1. Make the /opt/novell/iprintmobile/bin/certman.sh script executable: chmod+x certman.sh

    2. sh certman.sh -t utils -c

    3. sh certman.sh -t cert -s

    4. sh certman.sh -t cert -g

  2. On the Windows computer, do the following:

On applying the security patches, the existing Remote renderer continues to work without any issues. The above issue is encountered with a new Secure Remote renderer or re-registration of the existing renderer.

14.4.2 RPC Error is Displayed When Accessing Management Console

Certificate validation fails if the third party certificate is already configured and activated before configuring iPrint Appliance server.

To resolve this issue, configure the iPrint Appliance server again and then upload and activate the certificates.

14.4.3 Upgrading iPrint Renderer From 1.0 or 1.0.1 to 1.1 Corrupts the iPrintRenderer.conf File

If you have upgraded the renderer from 1.0 or 1.0.1 to 1.1, the iPrintRenderer.conf file gets corrupted. On corruption of this file, the renderer also fails to uninstall.

To resolve this issue, do the following:

  1. Replace the contents of the c:/NDPS/Renderer/Conf/iPrintRenderer.conf file with the following:

    Word=doc,docx,rtf,docm,dotm
    Excel=xls,xlsx,xlsm,xlsb
    Powerpoint=ppt,pptx,pptm,ppsm
    inBuiltPDFRenderer=pdf
    #Adobe=pdf
  2. On your client workstation, uninstall the Renderer.

  3. Install the latest renderer. For more information, see Installing and Configuring a Remote Renderer.

14.4.4 PowerPoint Job Fails to Print

If the remote renderer configured with Microsoft Office 2013 is under continuous load, then it may fail to print PowerPoint jobs. This issue is not caused if the remote renderer is configured with Microsoft Office 2010.

To resolve this issue, stop and start the remote renderer.

14.4.5 Jobs Fails to Print

If the remote renderer is configured on Windows 8.1, Windows 2012, and Windows 2012 R2 server, then over the period of time, you might encounter consistent print failure. This is because the in-built pdf renderer might have stopped responding.

To resolve the issue, restart the remote rendering service using the following commands:

  1. To stop the renderer, run iprntrendcmd -q

  2. To start the renderer, run iprntrendcmd -l

14.4.6 Remote Renderer Status is Inactive

Sometimes the remote renderer status might change to Inactive and activating it from the Management Console also fails to change the status.To resolve this issue, restart the renderer using the following commands:

  1. To check the status of the service, run iprntrendcmd -s

  2. To start the renderer, run iprntrendcmd -l

14.4.7 Remote Renderer Status is Inactive After Appliance Upgrade

If you have a remote renderer associated with the iPrint Appliance, then upgrading the iPrint Appliance changes the remote renderer status to Inactive. To resolve this issue, follow the steps from Downloading the Remote Renderer to Registering the Remote Renderer to download, install, and register the new renderer.

14.4.8 iPrint Rendering Service Hangs

The iPrint Rendering Service might hang with the service status “Stopping.”

This issue is caused when the remote renderer fails to restart when using the configuration or registration commands.

To workaround this issue:

  1. Launch the Windows Task Manager.

  2. Click the Processes tab.

  3. Check the Show processes from all users box.

  4. Right-click iPrint Rendering Service.exe, then click End Process.

  5. Start the remote rendering service by using the iprntrendcmd -l command or through the window services panel.

14.4.9 Printer Drivers are Missing After Registering the Remote Renderer

After registering the remote renderer, self-signed and un-signed drivers are not installed.

To resolve this issue, run the command, iprntrendcmd -rt <FDN or IP Address>

On the prompt, accept the certificate for each driver.

14.4.10 Local Renderer Fails to Print the Password-Protected PDF Files

The local renderer fails to print password-protected or corrupt PDF files.

You might get a message in the audit page that the job is complete or success message for email printing, if the local renderer uses the pre-packaged driver for printing.

14.4.11 Printer Prints Junk Characters

When trying to print a document, the printer might print only junk characters in the following scenarios:

  • This issue is caused because the local renderer does not support all the font types. To resolve this issue, you can install the Microsoft TrueType fonts on your iPrint Appliance server.

    1. Log in as root.

    2. Type the following command to navigate to the fonts directory, then press Enter:

      cd /opt/novell/iprintmobile/fonts/

    3. Install the supported RPM files by typing the following command, then press Enter:

      rpm -ivh *.rpm

      The RPM files are now installed on the iPrint server.

    4. Run the script to retrieve the fonts by typing the following command, then press Enter:

      sh fetchmsttfonts-11.1-5.7.10-fetchmsttfonts.sh.txt

      The fonts are downloaded from Sourceforge and installed on your iPrint server.

  • Few of the Linux drivers might fail to print due to absence of certain filters. You can verify this information, using the command: lpstat -p

    The command displays the status of the drivers. Change the driver for which you have received the failure messages. This is applicable only for local renderer.

  • If the remote renderer is registered with Built-in-PDF Renderer for processing the PDF jobs, it might print junk characters for PDF files.

    To resolve this issue, you need to reconfigure the remote renderer using iprntrendcmd -c command.

  • If the remote renderer is not registered for PDF file processing, the printer might print only junk characters and not the actual content. This can be caused by an incompatible printer driver.

    To work around this issue, use the drivers that are compatible with your printer.

14.4.12 Remote Renderer Fails to Start Because of Login Failure

The remote rendering service might not start if the credentials provided are incorrect, or if the user account does not have the Log on as a service rights.
