New HPLIP version 2.8.6 available in hplip website. Please add it to portage.
Yes, Please do!!!!!!!!
I tried 2.8.6 by copying the ebuild from 2.8.5 on my new HP F2280 which is only supported by this latest version. At first it didn't work, it bailed out with a foomatic-rip or gs error in cups error_log (with cups set to debug mode) when printing a testpage. Don't have the log anymore so cannot lookup the exact error. After upgrading to net-print/foomatic-filters to version 3.0.20080507 everything seems to work fine on my new HP F2280. (I had 3.0.20070501 installed first as 2.8.5 required).
hplip-2.8.6b was just committed today. Thanks for reporting. Denis.
