I'm having trouble printing with Gentoo, and CUPS. I have configured CUPS and the HP driver correctly (well I think) and when I go to print a test page it'll print a page which is 100% black. THis happens on 600dpi, and not on 300dpi, but I want 600dpi since the quality of images on 300dpi is bad.
I've recently found a small app named ufed which helps you choose USE flags for Gentoo. It reads the /etc/make.conf and gives you a list of all the USE flags available and alows you to read a description, select and save new USE flags. It's usful since I don't know each and every USE flag off by heart.
