Thanks Ben for some great ideas. Based on your tests, spooling is very fast. Printing is slow.
Printing to a local port c:\test.prn is also very fast. Printing to an "HP Laserjet 4" printer is pretty fast. 3-4 seconds. The Konica is configured to use a Standard TCP/IP port. Bidirectional support is grayed out. Print Spooling is enabled. Network port on the Cisco switch and the Konica are set to Auto Negotiate.
