Notes on Printing
If you’d like to print any of these documents in black and white, you can just set your print settings to “greyscale” in the dialog box that appears when you press the print button.
Letter and A4 refer to the size of the paper each document is designed for—letter is most common in the US, while A4 is most common just about everywhere else.
Most of the pdf documents are in vector format so they can be used for hi-resolution printing.
