I've tried Sibelius and Finale, and while they are extremely powerful, they are also extremely complex to use.
The software I use is called Noteworthy Composer, and while it doesn't have 'true' support for drum notation, in that you can't put a snare in the right place and have it sound like a snare (you can use midi remapping tools to fix this, which is what I do), you can change noteheads, and do most notation-related things.
The only features that I would like that it is really missing is pre-mapped, or internally mappable percussion notation (ie. the midi mappings), and the support for odd subdivisions other than triplets. Fortunately, for things like quintuplets, you can insert text markings, and invisible tempo markings and time signature changes to get around that shortcoming.
Entering notation is quite easy - you use the arrow keys to move around the staff, the Enter key to place a note, and Space to place a rest. Select the active note value from whole notes through to 32nd notes with the 1 - 6 number keys (64th notes are available but not mapped to a shortcut key), or click on the button in the toolbar. 7, 8 and 9 provide accidentals, and are toggle buttons. As I said, it is VERY easy to use straight out of the box, it also has a small, but dedicated community who provide a lot of help and ideas for things.
Unfortunately, I have just discovered the demo version doesn't allow you to save or open anything, but You'd most certainly be able to draw something up (It'll take you about 30 seconds to write up a 4/4 rock beat once you've got the hang of it) and then take a screenshot, though
I don't know if the demo allows you to print, and if so, then you'd probably be able to print to PDF using CutePDF or something like that.
Anyway, you can get the demo here:

Oh, and it's also quite cheap for powerful notation software - USD $49
I apologise for sounding like a walking advertisement
. I've been using the software since around 1998 or so, I think originally on version 1.1. If you can find a copy of the 1.75 demo or earlier, you could save your transcriptions up to 10 times, so that might work out for you
. I personally didn't purchase the full version until about 5 years ago, when I found out someone had used MidiOX and MidiYoke to re-map midi channels for drum notation. I have posted a list of what I consider appropriate mappings on the forum.
