Configured new HP printer to work with new (i.e. intel chip or ios) Macs just fine.
The one older iMac G5 PowerPC is the problem. It printed, but only in B&W.
I installed the latest gutenprint (I knew it as cups and gimp, I'm an old timer tech). Then I had several models of drivers to choose from (blindly) when adding the printer.
Looked at documentation on site and it talked about color vs b&w being a basic choice. Um, where? How?
Printer model HP Photosmart 6520
IMac G5 OSx version 10.5.8
Test printed from iWorks with text and some graphic scribbles in diff colors. Output fine, just grey scale, no colors. Old direct USB connected HP printer worked fine so know iMac and software are capable of color. Just want more desk space while learning new before ditching old. Thanks.
