To keep jobs in FIFO order you could adjust the file C:\Program Files\Xerox\FreeFlow Core\MantisService.exe.config to have the maximum simultaneous jobs set to 1. It will impact performance as one job will process at a time. See key below.
<add key="maxSimulJobs" value="2" />
i am using a manifest to print an order i need FIFO for. i use distrubute node to distributer to two different
job tickets - two different stocks. each printer of the two has collect job documents bui cannot get the right order at the print queue.
