Thanks I tried the new driver. Installed with easy start - does not work - reads the printer - send a print job - then unable to send to printer error. Thinking about the 452dw so I could do the AirPrint. Got to read up on AirPrint, but it the short blurb I read sounded good. Thought I could ethernet the 451dn into the router and somehow print that way - nope. Even the chat with apple support said that for airprint the printer itself has to be wifi, but on another site it said to just use the ethernet. Figure the apple support chat would have gotten it right though - maybe?
As for the brother printers - seems like the 3 we have had at school had issues all the time. THe HP 452 somehow has a drum with the toner cartridges so there will not be drum replacement later. Still trying to figure all this out. Ordered the 452dw to the store - will arrive on Saturday so I have until then to make up my mind. Thanks again for any advice.
