There are some issues with printing and margins. See this thread:
Printer Margin Issues. Be sure to send in the feedback that you need this to work better!
The black and white issue can be attacked by using the PDF button on the print command to save the output as PDF. Open the resulting file in Preview, select Save As... and save it again, except this time turn on the Quartz Black and White filter. Now you can print in black and white. For some reason, Apple took the ability to run this filter out of the Print dialog in Leopard!
