Well, I just looked up Print Spooler on the web 
and it seems to be a separate programme used by other apps to send stuff to the printer. So someone would need to write one of those as well as write printing support into the actual apps?

Like CUPS (the print spooler packaged with KDE), for example; but it would have to be packaged separately if you don't want to recommend KDE.

It would be nice if there was some way to print from the normal tablet environment, so it would be exactly like it is now but there would be a "print" option in the menus of certain applications.

You should get an adapter, they only cost a few pounds/euros/dollars but they let you do lots of interesting things with the tablet. Attaching a keyboard alone has made it worth my while.
In order to know the power requirements of the peripherals befor plugging them to your tablet, you can connect them to a linux machine and issue the command "lsusb -v". This dumps a lot of information for each connected usb device. Most of this information is arcane for me, but you can easily spot the line about MaxPower.
Of course, you don't have to worry about power consumption if the peripheral is self-powered (such as a printer), or you are connecting it to the tablet through a self-powered hub.
What I'm still not sure about is: what could happen to your tablet if you exceed the allowed power consumption? I think that the usb device simply won't work, but... Can someone confirm that there is no damage for the tablet?

Correct. The tablet will nicely reject devices that ask nicely for more power than possible, but if a device (like a USB fan/light/flowerpot/whatever) draws more power without asking, the N800 detects the overcurrent and shuts the port down. No damage.

The reason I made the tutorial just about the keyboard is precisely because I didn't want people to think this would work with all USB peripherals.
However, it does actually work with a Flash drive, at least mine worked fine every time I tried it, and that's my next tutorial.
This method should also work with USB HDDs if they have an external power supply.

I don't think there can be any damage to the device supplying the power.

Is it theoretically possible that a developer could add printer support to a maemo app? It would be nice for example to have Xournal with printing support.
