Here's a suggestion for saving some money and it's free
and good for the environment.
Say I pay my insurance bill online. I print a copy of that to a pdf file. If it posts to my account, I delete the pdf with no ink, no paper wasted.
Or if I buy some items from Kohl's. Once I have the items in hand and I know I'm not going to return them I delete the pdf. I do this with all my receipts, etc.
I use PrimoPDF
http://www.primopdf.com/index.aspx to print to a pdf. I only use the free version, not the Nitro version. Totally unnecessary to pay money for the program as it's perfectly adequate with all the extras they try to charge you for. It installs like a printer so when you go in and select print instead of choosing your printer, choose primopdf. It's also a great way to send documents to other people.
ETA - I did just buy a Canon PIXMA wireless printer from Walmart. Anyway it was $50 and will accomodate more than one computer wirelessly. I've printed a bunch of papers plus 50 "licenses" for cubscouts on super high quality photo print and have only use 1/4 of the sample cartridges that came with it. It also has the option to add extra large cartridges which print more pages for only slightly more money.
