After that Windows install recognised the printer automatically and worked correctly, OS-X install was fine once I entered the address, and there didn't seem to be a Linux driver but it worked OK as a generic PCL5e printer.
Which brings me to my only question - it appears to have two modes, PCL5e and UFR II. Windows installed both, the Mac driver only installed UFR II. Is there a reason why one or the other should be preferable under Windows?
Later because of difficulty editing this page I wasn't able to say that it's VERY fast - 2-3 seconds from standby to first page out, and about four seconds to print a double-sided page.
