Hi list,
I've a printer model HP ENVY 5530 (AIO) configured in wifi. I've 
configured this printer on my C7(1511) workstation using hplip and cups.
Printer is installed e configured. After installation I try to send a 
test print page and it is printed. After reboot, I try to print other 
doc, and I got it printed only on grey-scale and if I try to send 
another test print page from hplip or cups I obtain a gray-scale print 
and half page with wrong size (like if the "image" is printed on A3).

If I remove printer and re-add it, the test page output mode is color 
but after a reboot it come back to gray-scale mode but in configuration 
is selected color.

hplip version is 3.13.7.

Can someone point me in the right direction?

thanks in advance.
