What is the present cost of Laser Printer for PC. How much 4GB/8GB pen drive costs now? How much expenditure it will be if I print 20 pages(Black & white) from a laser printer in my home? Is it worth purchasing a laser printer or it is better to get computer printout in market.

If your going to use WWG modles it is really worth getting color prints. As far as a thumb drive to carry it, I carry 6 sets on a 1G drive and have space left. I think Kinko's is around 20-25 cents a print. Buying a color laser is not a cheap upfront cost but I think you will find you save money on toner vs ink long term.

There is some debate about which is better though inkjet or lasers

I have a 4GB USB thumb drive that cost me $9 USD. It has all of my WWG purchases on it in both unzipped and zipped format for a total of 58 folders and files.

I saw an advertisement on 26 November 2010 for an 8GB thumb drive that was $12 USD. That was a two day special. The price of those drives vary greatly from store to store. Some charge a premium price for them. I always check all of the sales papers to see if anything shows up at a discount price.
