Cups got an upgrade on debian which removed all my printer config in cups and hplip. After an insurection by the professors here in the zoo i had to fix it pronto.
Hplip software (my blog) would not find a ppd file for an older printer and the newer ones also seemed to mia. I used cups instead which could find the things.
The only thing i used hplip for was photo printing on weird sizes.
i decided to make and compile the madam maybe it still has a use ?
The 3.18.6 release needs pyqt5-dbus which is only available in debian testing when i write this.
I was unable to compile it.
I am not running a testing distro just for a printer server.
I managed to connect to the usb printers with the older hplip i had complied over a year ago after messing about in the settings.
Not sure why they disappeared in the first place.
