Yes, which is defined as acceptable in the requirements speficiation of the system.

The thing is, printers go off-line, they go off to service (or get on location service). When replacing toner or doing repairs you manually print test pages on the printer. That's why it is nice to have accounting finished at the end of the job. Otherwise some poor user will get to pay for the test pages.

Due to the amount we print the cost per page pretty much averages out, black or colour prints. Also, this is less important, as a black printout may cost more (if it is 100% black) than a colour one (if it is 1% coloured). Also, our students do not have much choice. All printers are the same brand and they have default printes defined depending on workstation and lab. ----------------------------------------------------------------------------- YOU MUST BE A LIST MEMBER IN ORDER TO POST TO THE LPRNG MAILING LIST The address you post from MUST be your subscription address If you need help, send email to [EMAIL PROTECTED] (or lprng-requests or lprng-digest-requests) with the word 'help' in the body.
