QTR not showing up in print tool

Dear All,

all of the sudden QTR disappeared from the print tool printer page

I have done the following:

  • deleted the QTR in the application folder and in the library in printers, QTR
  • deleted the print tool app in the application folder
  • deleted the quad tone printer (9900 pro k5)
  • fresh install of QTR
  • fresh install of the print tool, however installation did not ask for a license key/demo license
  • added a new printer (9900 pro k5)
    no change
    Operating system: Catalina v15.4
    I am a bit of a loos here. I have done this installation many times successfully …
