Bug with Safari AirPrint - size of the printout is minuscule!

Hello

Me and other other HP users have been very frustrated with the lack of support from HP with regards to the above.

The problem is that since upgrading to iOS 11 AirPrint from safari has been rendered useless - the size of the printout is about 10-20 times smaller than an A4. AirPrint works fine when I’m using other apps.

I think this is a bug, but not sure how to report it!?

Thank you!
