• A printer is in error (e.g. a paper jam that the user was unable to clear)
• A printer's toner level is low
• Other errors occur in the printing process

• Define costs on a per-printer basis
• Full differential charging models taking into account standard sizes, size category, area, color/grayscale or duplex mode
• Combine with filters for precise control over charges and use
• Apply discounts to encourage use of grayscale and duplex printing
• Page-level color detection - users are only charged the color rate on pages that actually contain color.

• Automatically detect and delete duplicate jobs.
• Prevent large jobs from being printed on slow printers (encourage the use of high volume printers).
• Stop jobs of certain names/types. A great way to stop someone accidentally printing the "accounts.xls" file that results in 20,000 pages!
• Catch invalid paper sizes before jobs arrive at the printer. No more "manual feed" or "Load A5" blinking messages!
• Restrict access by domain group, maximum cost, color mode, size and more.

Filters are backed up by customizable messages. These can be used to inform users of why restrictions are in place. For example, "This job has been denied. Please don't print jobs over 100 pages on the ink jet printer. Use laser printer X instead."
