Yes, Universal Print Drivers are certainly limited to specific languages and the process of learning which is which could be more streamlined, I agree. I want to provide you two different links. It is up to you if you wish to respond but I think you deserve to have this information as it sounds like you have been a good customer for a rather long time.
Connect with the HP Executive Team - Click this link if you have any suggestions, solutions, ideas, and observations to help HP better serve you.
Contact HP - If you have any other questions or form of feedback, here is the basic site. You can navigate through here if you so choose to find a way to ensure you have reached out to a department higher than myself with your feelings you have expressed above.
Lastly, let me know if I can be of any more assistance. It appears you have resolved your scanning problem but if I read that wrong just indicate here where I can help you and if I can't, once again, I will point you in the right direction.
I only speak on behalf of myself on the forums but thank you for sticking it through and remaining an HP customer. I hope you are not having any more problems but I am happy to help you if so.
