I actually ran into this problem today — being forced to print something out with no printer around. The solution is Kinkos, which is ridiculous.
I do own a printer (that came bundled with an iMac I bought way back when) but it has been out of ink for months. To me the hassle to replace the ink just to use it once in the next six months outweighs the benefit.
The solution is pretty obvious though: everything you need to print out now should be completely digital in the next couple of years. I already sign documents without printing them out, get movie tickets without printing them out, get boarding passes without printing them out, etc. We’re almost there.
Now 3D printers on the other hand…
