Hi smart app won’t print in colour !

Like most on here I can no longer print colour from my iPhone hpsmart app. There is no option other than black and white. I have been on many forums and also chatted to ho themself but no one has a soloution why this has started to happen. I’ve tried every trick there is to try and get it to work including all these tips on apple forum. I pay a subscription for my ink which I will be cancelling if I cannot fix the issues. So annoying. Pleas has anyone managed to fix it ?
