I thought 5.0.4 was the latest. My mistake, the firmware rev was 5.0.4 , the driver shows 5.0.2. I looked in the executables, and no version number is listed, but the date is March 29th. They could have written an error into the version checking strings , and or the history cache is not being pointed in the right direction.
I have seen problems all too often when installing multiple HP printer drivers on Macs where the utility changes pointers in any which way. It's probably one or the other.
Thanks, Neil. It's good to hear that your driver is 5.0.2., too! Does your system tell you that the driver needs updating, too? Is there a way of cleaning out the cache? I wonder if other folks are experiencing this.
I wrote to HP about this, and haven't heard anything back yet..
