New version 1.6.9 available in hplip site. Copiyng 1.6.7 ebuild in portage overlay and renaming it to 1.6.9 compiles ok in x86 (using an AMd Athlon Xp 2600+). After compilation, i tried to print a cups test page in cups web administration page, a hp test page using /usr/share/hplip/toolbox and a 4 page document using Acrobat Reader, and it works OK.
This version fixes some bugs and add support for new printers and CD/DVD label printing.
I can confirm that this compiles well, and works well. In fact, all previous versions currently in portage won't let me scan, but 1.6.9 seems to have fixed the problem
thanks, fixed!
