@mathr that b/w image looks pretty neat!
hmmm, with narrow everything it doesn't print well - visible aliasing both horizontally (thin vertical gaps occasionally) and vertically (slightly thicker horizontal lines occasionally), not sure where it's coming from (printer is allegedly at 1440dpi, PDF is vector). maybe some part of the print head is clogged due to the third party ink cartridges I bought last time.
