Thanks for that. I read most of your paper, and you seem to be doing what we're trying to do, namely: - counting pages successfully printed by the printer, not pages in the job - use SNMP instead of proprietary solutions to collect info from the printer The problem I have is that synchronous printing and page counting causes a 17 second delay between jobs, due to the time taken between end of spooling and the first page coming out, which is due to the long paper path of our HP LaserJet 8150. I've drawn a diagram: http://www.dcs.warwick.ac.uk/~csuwf/printing.pdf (there's a .ps too) I have a solution currently being developed which involves using PJL to set the PJL-job-name of the job to the job-id (integer) from the print server. A filter will do this, then fork. The parent will return (so the server can immediately send the next job to the printer) and the child will be left alone to collect info from the printer about how the job did as and when it appears. This should enable accurate job-based page counting, which means fast asynchronous printing with no delay associated with the paper path being emptied and refilled. If anyone is interested in this, or has already implemented it, please let me know. Ashley GC.
