so I have a HP officejet 4622. If I'm understanding this correctly, there will be some form of CUPS similair to my old UBUNTU setup where you use a web interface to wirelessly send docs to print? will this beta allow me to do anything different, now than the hp dekjet 842c attached to my mini? I'm afraid I'm following here, but not getting it. I see the VPDF print doc, but nothing under postscript. I thought somewhere there had to be a web interface.
