Error fetching ipp data: Invalid response from API - error log every 1 min

Also getting the same on a HP printer.

For context, my printer is not always switched on (as I print rarely) and in fact I use an automation for when my printer goes into ‘idle’ it turns off the power socket.

I would also love to see it handle the state better when the printer is offline. For example, instead of it showing as ‘unavailable’ it should show as ‘offline’ or something similar, like this custom component handles it https://github.com/elad-bar/ha-hpprinter. And maybe retain the last know value of the inks

same on lexmark

I am convinced that the sensor could show Unavailable, but the toner level should be the last known, not Unavailable

@ctalkington could you take a look at this issue?
