Jobs Sent to a Windows Printer Have Pending Status

Problem

The LPS Status Client Application that allows the viewing of LPS printing activity from anywhere on the network. It allows pending jobs to be deleted and jobs to be reprinted on an as needed basis. Tree and Context views are provided to maximize the information that can be obtained. Any number of LPS servers can be monitored. Jobs can be viewed, resubmitted, or deleted with a right-click of the mouse. indicates jobs sent to Windows-configured Hewlett Packard (HP) printers are backing up with a Pending status and the printer is displayed as unavailable (red). Restarting the Loftware Service and removing pending jobs from the Loftware working directory (C:\Program Files (x86)\Loftware Labeling\WDDrop\OLEBPx) will often temporarily restore normal printing.

Explanation

There is a commonly enabled setting for HP drivers called Enable bidirectional support that, when combined with multiple configured printers using the same driver, can conflict with high-volume label printing from Loftware.

Solution

To resolve this issue, clear the Enable bidirectional support check box on all configured Windows drivers being used by Loftware to disable this setting.
