I never was able to make my 6 year old HP Designjet 488CA work with the old printer driver (HP has no updated driver available, they no longer support the printer) and Mac OS9 With Vectorworks 9.5. I upgraded to a new Mac with OS 10.4.9 and new Vectorworks 12.5 software, downloaded Gimprint and everything's working fine. My abrasions from being dragged into 2007 are healing nicely.
