Environment:
Corporate print room with 22 networked printers. It is a mixture of HP 8000 series and 8100 series printers running nonstop, 24/7.
The jobs are one million plus pieces, broken into increments of 4000 with checkpoints.
The .dat file for each job is located on the server, for retrieval by each printer.
The Data file is located on a seperate machine with a drive shared to the network.
The printing portion of the network is split by three hubs, each supporting approximately 1/3 of the printers.
Problem:
During printing, machines (at random) stop with a 79E error, causing the correction of start point and restart of that machine. The printer will begin printing at the start of the spool job and reprint records which have already printed causing unwanted duplicates and spoilage.
This problem was discussed with the HP technician. Technician stated that it was a network issue, that the machine was losing data long enough for that particular machine to halt it process.
Question:
What can we do to prevent this loss of data, and what failsafes can be implemented to monitor and/or correct such errors as they occur?
