Printer either does not print black or prints it faintly.  Tried maintenance tool suggestions to no avail.  Is it fixable?  Is it worth getting serviced.    Mark Luna
Is there a software fax manager that allows sending and receiving faxes w/o having to use the printer panel?  I've used HP AIOs for years and I'm used to managing sending and receiving faxes via a software utility. Mark Luna
