Lr printing problems - Canon Pixma Pro 100s

Some help if possible. I've been printing successfully with this printer from my iMac using Lr Classic CC. Having not printed for a while I tried yesterday and today and found the colours awful, strong magenta casts on sand and harsh blues in the sky.
I have calibrated my screen and bought a new set of Canon Inks, which have previously been fine. The paper is Canon semi-gloss. The machine is about 18 months old and hasn't had heavy use. Is it something in Lr or with the printer?

I've attached the original image from Lr and a snap taken with my phone - which shows the resultant print pretty accurately.

Hopefully it's something simple, but any help is greatly appreciated.

Many thanks

I've heard that a magenta cast is due to managing colour with both the printer and LR. Make sure that it's managed by just one of them.
