Looking to Print Customized Cards, Thanks for any feedback

One of Akoha‘s inherent charm is how it manages to tie an offline game with an online component. It gives much more meaning to the service, and certainly a better experience for members of the website.

One of my current ideas right now is to be able to print business cards-like from this section of TechEntreprise. So you sign up there, fill in a few information, and afterwards you could get a “member card” that can be used for local events, with details about what’s your profile (a web programmer, a designer, an investor etc.), and what you’re looking for. Other ideas:

• show the username so people can hook up with you just after the event,
• have color codes on the avatar depending on your profile,
• list projects you’re working now currently etc.
• being able to print on different kind of papers (such as a special color for a special category of the website’s members)
• being able to completely automate it (and not spend hours printing one business card)

Now, I’m vaguely aware that one can get sheets of blank business cards-like at a store like at Staples, and then print them from your laptop with a normal printer; but from my perspective, you need special software plus they do have a fixed size for the business cards.

Does someone here have experience in these sort of thing? what kind of setup is needed (such as what kind of printer)? Is it possible to print it with the HTML or TechEntreprise will have to render it in PDF?

Thanks for any feedback :-)
