For example, in Ubuntu 8.04, when a file was added to the print cue, it printed immediately if the printer was ready. In 10.04, there's a 10-15 second delay between the start of the job, and when the printer actually starts printing. From searching the Internet exhaustively, I've found people using other Linux distros reporting a similar problem, but no solutions offered.

This is the SNMP code getting the final page count; add "*cupsSNMP: False" to your PPD file and the delay will disappear.
