Re: (Score:3)
That's only nominally 240V. Many circuits that are called 240V are actually 208V split phase, i.e. the voltage between two phases of a three phase, 120V phase to ground circuit. Since the voltage ratings are usually given +/- 10%, a device that's designed for 220-230V can use either 240V or 208V. And electric ranges often draw more than 30A. More powerful modern ones can be 40A for single oven or 50A for dual oven models.

Re: (Score:3)
It all depends on how much and how you use it. If you were to print only some single sheet documents the inktjet is probably cheaper, because otherwise the printer would have to heat up for each print (smaller cartridges would also be cheaper) . If you have to print 50 pages at once once a week (and let the printer be off in between) the laser is cheaper. Everything boils down to how you use it.
Except inkjets don't take well to only being used occasionally. You end up having to clean the print heads for every document, wasting a lot of ink and several test pages in the process.
Re:All that current? (Score:4, Interesting)
A laser printer is always cheaper, hands down, no questions asked, every time, unless you want photorealistic pixel-perfect quality, don't mind the cost, do it regularly and need to have it done immediately or without anyone ever seeing a potentially horribly illegal printout.
Laser printers can sit on the shelf for years, literally, and the first or second page printed will look as good as the last one from years ago. If the storage room is dry enough, unused laser printers and their toner will last for ages, they're ready for printout in seconds - if you manage to get the driver working after all these years - and the quality doesn't diminish in the least.
Inkjet printers, on the other hand, will dry out. Print heads will be slowly blocked by solidifying ink. Nozzles will be blocked after 3-9 months in storage, depending on humidity of surround air, requiring head cleaning, which wastes ink, test runs that waste ink and if nothing helps the almost iconic all-black page, where the ink slowly comes through the solid residue, also wasting ink. After 12-15 months, tiny ducts within print heads will be all-solid ink, with at least some nozzles never to be recovered through any means. For HP or Lexmark models, where the print head is included in the cartridge, getting a new cartridge will recover the printer - after investing 30-50 EUR on the cartridge. For Epson and Canon models, where the print head is irreplaceable, this means game over.
I think it helps to make one thing clear:
As long as brand-new b/w laser printers are under 100 EUR, and under 200 for color, and digicam printouts are less than 0,10 EUR when ordered online or a local 7-11-type store, all typical "home" use cases of an inkjet printer collapse immediately.
- Small digicam printouts run 0,30 EUR per page. Online order is less than half of that.
- Black-and-white pages, medium volume (1000 pages/year), run at 0,15 EUR per page. Laser printers run at 0,07 EUR per page for this.
- B/W pages, low and lowest volume (100 or 10 pages/year) run at 1,50 EUR per page, if calculated realistically, since the printer must be paid-for, and then the ink dries up after a year of no printing. Local copy shops print out at 0,15 EUR per page and their ink never dries, their quality should be perfect (or you'd find another one) and you don't need to buy your own printer first.
- Color pages, lowest volume, run at 2,00 EUR, since there's two cartridges drying up after a year and needing to be replaced. Local copy shops do it for 1,00 EUR per page.
- Color pages, medium volume, run at 0,30 EUR per page, laser printers can do for 0,15.
So the rule of thumb can be put shortly:
"For a typical home today, it is never economical, not useful and not beneficial to buy a new inkjet printer or a new inkjet cartridge."

As far as I know, it's very difficult to cause a dangerous situation with UK wiring, unless you've got some dodgy imported stuff or have some bad DIY. The fuse in the plug of the power strip will prevent you overloading the socket.
However, I've seen travel adaptors sold for use by Americans in the UK without a fuse (or covers over the terminals, or plastic sheaths around the base of the prongs). This is dangerous, since the circuit breaker is usually 30A... a short circuit in an appliance with a US plug connected to one of these adaptors could draw 30A, until the appliance's wire catches fire. (A travel adaptor sold in the UK for use by Americans would have a 3-5A fuse in the adaptor.)
Of course, none of this would be necessary if the circuit breaker was, say, 15A. Although then you'd have to have a more substantial cable for your laptop charger and table lamp.

First proper company I worked for hired me because they were firing their (incompetent and expensive) outsourced IT and getting an in-house team. Most of the company servers were run out of a colo facility a couple of miles away but the head office ran half a dozen servers in a 48U rack in what was essentially an oversized broom cupboard.
Crowning moment of stupidity was when we discovered that, instead of installing the extra mains rail like they'd been paid to do, they'd instead used a daisy chain of gangplugs inside the cable ducting. One of these had obviously blown from the load previously - the plastic all around the socket was melted, as was the plastic insulation on the plug prongs itself. Why? It was a cheap gangplug (I doubt it even confirmed to British electrical standards, the plastic was exceptionally brittle) that was only rated for 3A (i.e. capable of delivering 720W max), but had been refitted with a 13A fuse (allowing 3.1kW) after the first fuse had blown (there were still brown burn marks on the fuse clips). It was warm, verging on hot, to the touch when I found it. Even more outrageous was the fact that the PAT people who'd been in two weeks previously hadn't noticed this error.
With proper cabling though, it's easy to run a dozen boxes off a regular 13A outlet... just woe betide someone plugging in the 3kW kettle or the 2kW laser printer at the same time.

As others have properly pointed out, the number of items is irrelevant, at least if safety was the intent of the question.
The total maximum current draw is more significant, as is the kind of load put upon the circuit. A refrigerator or air conditioner is a different load than a heater or hair dryer, which is a different load than a transformer-powered device, which is again different from a switching power supply device. They each have their little electrical "quirks" and draw power somewhat differently, and that does matter with regard to the load you're asking it to provide.
A lot of people think that the house wiring can supply a certain, finite amount of current, limited by the safe rating of the outlet. For example, they might assume a 15 amp 120V circuit can supply the 1800 watts the math suggests (A x V = W). Even if they're aware that this 1800W is only available at the breaker box, not after the losses in getting that power to your outlet, and even if they're aware that the utility may not be always supplying a steady 120V (if, for example, the utility drops voltage to 110V for a few hours a day, the maximum falls from 1800W to 1650 for that time period) they still see the power outlet as supplying a finite amount of energy.
That's not how it works (and professionals, please excuse the simplification of what is to follow). The outlet will happily and dutifully try to supply whatever you ask it to ... if you plug in 2200W of "stuff" into the outlet, your electrical system will try it's very best to give you the 2200 watts. It will probably even succeed for a while (maybe not 2200 watts, but some value greater than 15A and 120V), given a well implemented setup and solid work by the electrical contractor who built your home. In fact, the utility and your home wiring are often robust enough that you may get away with that overload enough times that you may believe the number of things you've plugged in is a safe load. After all, you plugged in that "extra" thingy and it worked, right?
It's protected by a breaker at the utility service entrance, right? That breaker is rated at [some value] so as soon as you ask for more electricity, it will trip and tell you it's too much, right?
Wrong. The breaker has no idea how much electricity you're asking for. It doesn't trip at 15 Amps and 120V. It senses heat, an indirect measurement of voltage and current, not a metered, precise amount. Breakers can fail, each time they trip they become somewhat less reliable, and they only are built to "guess" that a certain amount of heat is equal to a certain amount of electrical load. They're not speedometers.
So, it's an overload. There will be heat and sparks and who knows what happening inside the walls. Sooner or later, there will be a fire.
It's not like the garden hose where given your water pressure and size of lines, only so much water is going to come out. Ask your electrical system for more, and it will give you more. Until the fire, that is.
A certain safety margin is required, and that depends on the age and condition of your wiring, the quality of your utility's power delivery, and a few other factors. The best advice is to use a safe load limit as your guide; from standard North American power that would be probably around 1350 watts at the outlet. Go above, and trouble might be the next thing that happens.

That's not quite right. A resettable breaker (i.e. not a fuse that has to be replaced) measures two parameters. The first is indeed heat. That's to trip before the wire reaches dangerous temperatures in a moderate overload for a long time scenario.
