Hallo , i have written many times that youmust offer the HPLIP APP , but you do not.
Man people worldwide are using Hewlwt Packard Printers and by this MFP Printers for Print and Scan. Must they really search many time to find such way to install their printers? I think they go suddenly away and to MX linux o others. Ther is ! If someone test your software over USB and can not print - dramatically is that.
Next:
You also not have in your software download available Micrsoft fonts needed for wine, so people are have many problems using your wIne.
Next:
it is not good to say 18core run with 2 GB RAM. In reality there is really to small space. Only one programm is possible and the documents must be very small. Kubuntu and others are most smaller with their XFCE Versions and can run better with 2 GB ram.
So you can install Microsoft fonts:
I agree with you that Zorin Group shouldn't advertise that only 2 GB RAM are required for Zorin core.
I guess, You mean Xubuntu and not Kubuntu? Because Kubuntu is with KDE. But in common I agree with Point 3. 2GB RAM is ... thight.
For this, You must know that the Microsoft Fonts need an Licence Agreement. You will be ask for this when You install it. I think that is the Reason why it doesn't come preinstalled. It is a Licence Thing.
For the HPLIP GUI: Theoretically, You don't neccessarily need it because the hplip Package is installed and it should be possible to set up the Printer with the Printer Settings. Of Course this doesn't work every Time for everyone. And not everyone has a HP Printer.
