Please help us with the following details:
Would you please try to clean the print head and then try to print once as well.
my lightroom version is 4.4 64-bit
my operating system is windows 10 upgrade from windows 7
my printer is hp photosmart c6280 all-in-one.
I have cleaned my heads and it has made no difference, but it works fine printing from my pictures folder but will not print straight from lightroom it was, then it suddenly decided not to, I find I get better quality photo,s when printing from lightroom but at the moment I cannot print from it, it seems as though the printer is not reconizing lightroom.
many thanks MR. P. CHANEY
