Could not print on MFP through Laserfiche Scan

Hi there,

One user is using MFP with Java version 12.x, and it failed to print successfully from our application Laserfiche Scan 1.1.

In our application, we will convert doc to pdf first, and then print pdf from the MFP directly using print service. When user tries to print any document from Laserfiche Scan, it will be failed. It will finally process printJobFailed event. Attached is the log found from the machine. It said 'PDL leak detected', and then "FUNCTION USE STATE ERROR RETURN!! ret = -99"

Do you know why the printJob could not run successfully from the log?

Thanks a lot,

Juan
