Hi,

I noticed the print-manager kcm module correctly shows my printer's ink levels. I searched the code a bit and found they are described there as "marker levels" but I didn't find any reference to an implementation showing a warning when ink levels get low. So my question: is this implemented? If not, what would be the necessary parts to implement such thing? 

Reproducible: Didn't try

Steps to Reproduce:
ink gets low

Actual Results:  
nothing happens

Expected Results:  
a notification could be shown to the user informing about the low level
