Printing emails from Evolution

[Andrew]

I'm running karmic (ubuntu 9.10) with Evolution 2.28.1 and am having
problems printing emails - eg flight tickets from e-bookings. My
printers (HP colour laserjet 3500 and deskjet 1120C) appear to be
installed correctly and print OK from other applications, but apparently
refuse to respond to requests to print emails. Has anybody else
experienced this problem and any suggestions for solution please?
