For this scenario, the best printing method would be photocopying. Photocopying is very cheap for large quantities and suitable for single color, basic flyers that just need to be handed out on the street. Photocopying can produce 3000 copies very quickly at low cost. No special skills are required beyond operating a photocopier. While the quality may not be as high as other methods, for temporary flyers being given away, photocopying provides an excellent low-cost solution.
