Fixing those pesky PNGs

24th March 2011

I’ve been struggling with PNG colour matching for a while. It’s fine on my Linux boxes, with a standard sRGB colour profile, but on Macs and Win/IE with an ICCP in place, the colours never match up with the CSS colours. This is always frustrating, as PNGs are so nice for proper alpha transparency.

Canon iP1500 Ubuntu Driver

27th January 2010

The iP1500 is a cheap, reliable little printer, but Canon didn't bother with Linux drivers until recently. They now publish a driver for this printer, but it is a bit old and compatible with RHEL 3 and Suse 9.1, so in rpm format.

Apple annoyingly disabled CUPS browsing on Leopard. It always worked in previous versions and is particularly wierd as they own the CUPS project.
