We had blue coming out purple on one of our 800ps plotters,
and plotters with a newer version of firmware have a paper
option called 'Plain Paper-ec' that fixed it for us.  Have
you tried that one if available?

  I have an HP Design jet 800 that has been getting VERY heavy use (25 42"x47"

  We have since reset the printer to factory defaults, reinstalled the
  drivers, tweaked all of the available software settings, attempted a custom
  color profile made specifically for the paper from HP's website, verified
  that we are at the latest firmware version, changed paper rolls and swapped
  out ink cartridges.  None of this has worked.  Blue still prints out as
  purple.
  
  Has any one seen this behavior or know what we could do to fix it?
  
  Thank you.
