First, one need not spend $10,000 on a printer to get a wide gamut. To be specific, to PRINT wide gamut, you don't need to spend a lot of money. There is often an implicit association between managing color and printing wide gamut, however the two are actually separate activities. These days, the actual process of managing color is automated by ICM, which reduces the complexity of color management to choosing the right ICC profile for your printer and paper, and just printing. That will usually get you great results most of the time. So right now, I am assuming that, based on the wording used in your question, you are simply looking for the ability to print on a wide gamut printer, and not looking for a dissertation on the nuances of color management (which encompasses a lot more than just printing.)

The sub-$1000 Canon PIXMA Pro series and a couple Epson printers are all capable of printing wide gamut on a variety of papers with high quality pigment inks. Usually, a $10,000 printer gets you extra commercial-ready features, like ultra large format, roll printing, built-in hard drives to store queues prints, built-in color calibration features, monster ink tanks that can survive printing a single 60x40" print, etc.

Printing at a wide gamut is more about making sure your tones and colors are within the gamut of the printer, for the given type of paper, than anything. For that, you do not absolutely require a high gamut screen. You could, technically, get away with just Photoshop.

When it comes to printing, there is actually nothing that will stop you from printing a wide gamut print if you don't have a wide gamut screen. The printer will print what it's told to print. The difference is that you will have trouble judging the accuracy of the print if you have no accurate source of reference (i.e. a wide gamut calibrated screen) to compare it with.

The key thing about preparing an image for print on any printer is making sure the colors will fit within the gamut of the print. That means, for the given set of printer, ink and paper...do the colors of your print fall in or out of gamut. Photoshop, and even now Lightroom v4 and up, offer soft proofing. You can soft proof your photos, which will give you a simulation of how the image will look when printed, with the option of simulating black point and paper color tinting. For these particular features to be valuable, you still need a wide gamut calibrated screen...if your laptop can only cover 60% of sRGB, that's going to be tough.

Another feature that Photoshop offers is the gamut warning. With this, even on a non-calibrated and otherwise ineffective screen, you can at least see how much of your print may result in a gamut error, which either requires manual tuning to bring that region of your print back within gamut, or the use of a scaling ICM rendering intent. Relative Colorimetric will scale in a methematically pure manner, while Perceptual will scale in a manner that generally maintains how human vision perceives the photo. Using either of these rendering intents is usually sufficient to get a good looking, generally color accurate print. If for whatever reason these do not suffice, there are a number of techniques you can use to manually bring out-of-gamut colors back into gamut (usually with masking techniques and some desaturation of a hue-restricted color range), tweak black and white points, etc. (The details here are probably best left for other, more targeted questions.)

For the most part, when you print, so long as you are using a quality printer, with quality papers and a proper ICC profile, you really don't have to worry. Tell Photoshop or Lightroom to print, and it'll happen. Most of the time, your prints will come out extremely well. If you don't already have a hypercritical eye for the minor kinds of defects that an extra $9000 is going to help you fix, then you don't need all that other fancy crap anyway. You'll be satisfied with your prints. You will have to use direct judgement to determine if the color looks right, you won't have anything to compare to with a screen that only covers 60% of sRGB. A number of other print tests, such as for metamerism and gloss differential, are performed directly in various kinds of lighting and at certain angles to the light anyway, so a calibrated wide gamut screen is unnecessary.

So long as you don't expect 99% accurate color reproduction, which is really going to require a nice high end, high quality wide gamut screen such as the NEC PA272W, or an even higher end LaCie or Eizo, for best results, there is nothing that will actually PREVENT you from printing wide gamut prints on a $1000 to $1500 pigment-ink printer. For that matter, the NEC PA272W is only $1200, so you don't even need to spend two grand on a monitor. You could probably get away with spending $2000 in total on both a screen and a printer, and then you really wouldn't have anything to worry about at all. The printers only really need to get more expensive if you really need to print on papers larger than 13x19"...a 17x20" printer is probably going to start at around $1500 or so, and for anything larger than that your definitely looking at over $2000 just for the printer.
