(FORTUNE Small Business) – It's almost five, you need that report printed and bound on your client's desk by tomorrow morning--or even later tonight--and she's a thousand miles away. Do you (a) rush to Kinko's, seethe quietly while waiting, then desperately try to beat the FedEx deadline, or (b) sit down at your computer, click the mouse a few times, and go home?

If you chose b, you've probably signed up with one of the new overnight or same-day online printing services. I tested three of them, and while they all work basically the same way--upload a document over the Net and let the service do the printing, binding, and delivery for you--significant differences exist in cost, delivery options, and especially the quality of the final product. Choose the wrong service, and the document you designed to be as stylish as a fashion model may emerge looking like Frankenstein's monster.

Cost? Who cares when it has to be done so quickly? Our test file (a ten-page WordPerfect for Windows file containing full-color graphics and footnotes, and with a typeface that can't be found on most Windows systems) cost about $60 to get printed and bound at the neighborhood Kinko's and then shipped overnight via FedEx. I was pleasantly surprised to discover that Mimeo.com cost only $21 for the same thing, NowDocs, $27, and Kinkos.com, $37. Not bad. Let's hope that lasts.

Overnight delivery seems glacially slow when you can get it there in a matter of hours. NowDocs.com offers two-hour delivery to 16 cities (if ordered by 6 p.m.), and Kinkos.com has four-hour delivery to 20 cities (8 p.m. deadline). If you aren't sending that presentation to a major burg, both offer overnight options for the rest of the country. Mimeo.com doesn't do same-day delivery but can ship overnight anywhere in the U.S. or Canada with a procrastinator-friendly 10 p.m. cutoff. Each service met its promised delivery goals during our tests.

While it's tempting to pick a service based solely on speed, quality must come first. NowDocs bungled things: The photo that belonged on page two of my report appeared on page one, the typeface was close to the one I specified but not a perfect match, and the printed text had a slightly uneven look. Kinkos.com came close to perfection, but Mimeo.com's printout edged it out with sharper text and subtler colors in the photos.

If it can wait till tomorrow, I'll send my next document through Mimeo.com. But if it has to be out today, I'll hope the destination is in the Kinko's service area. Either way, long lines and deadline pressure look to be a thing of the past.
