On iPrint Appliance 1.1, when you enable a printer for mobile printing, the server performs additional background tasks such as driver download, installation, and configuration. Though the printer is immediately enabled for mobile printing, the print jobs might go through the default driver configured for local and remote renderer(s). If the default driver is not compatible with the printer then it can lead to poor quality printing. It is recommended that you test the printer by issuing test prints to ensure that newly enabled printer is configured correctly.
Check the mobile server logs for any related errors to ensure that there are no failures with the printer configuration at the local or remote renderer(s). If you notice errors in the mobile server logs indicating a failure at the local or remote renderer(s), try following steps to resolve the issues.
Disable the printer for mobile printing to avoid users printing to it.
Ensure that the print manager is running.
Ensure that the Driver Store is running.
Ensure that the driver is present in the Driver Store for the renderer platform, and is associated with the printer.
Try installing the printer from the IPP page for the corresponding platform on which renderer configuration failed. This shows the exact error indicating the underlying problem.
Enable the printer for mobile printing after fixing the error.
