Re: Print dialogs
In addition...
Printer drivers that don't use metric tonnes as the unit of measurement for the file size, can cope with something exotic like changing the connection between USB, cable, or Wifi without having to reconfigure/reinstall everything, and don't pop up useless information often to people who aren't even printing at the moment.
Printer dialogs that use every print opportunity to decide that the user wants to go back to printing in colour unless they find where the checkbox is hidden.
Printers that don't get through ink like a fish gets through water.
