Computers replaced blueprinters decades ago, so you may have a problem there. Even if you can find a blueprinter, I doubt that you can find the needed ink and paper for it.

To create a new Programmable Search Engine, all you have to do is choose which sites to search and give your search engine a name. 1. From the Programmable Search Engine homepage, click Create a custom search engine or New search engine. 2. In the Sites to search box, type one or more sites you want to include in the search results. You can include any sites on the web, even sites you don’t own. Don’t worry, you can always add more later. 3. In the Name of the search engine field, enter a name to identify your search engine. For tips on naming your search engine, see Branding guidelines below. 4. Once you’re ready, click Create.
