In the properties of an iPrint printer that I've installed on my
workstation, I tried to set it so jobs are printed directly to the printer
as opposed to spooling first. I can apply and ok this, but when I go back
into the properties it has reverted back to spooling.

I've encountered an issue which is resolved by creating a new TCP/IP
printer port, installing the printer that way and telling the driver to
print directly to the printer. I can't change this setting with iprint

Any ideas?
