A network printer (P4014n) would not collate when printed to from a Windows 7 workstation. Windows XP workstations on the same network would collate. Collate is the checkbox in the bottom right of the printer dialog that would keep a report in printed order. In this example, we used the end of day report.
The printer was installed on Windows 7 using an IPP ((Internet Printing Protocol) port instead of a standard TCP/IP port as used on Windows XP machines. Reconfigured the printer port to print to the TCP/IP port allowed collate to work.
