I'm an OpenOffice devotee, but your daughter would probably be best off with Word. I don't know how "online" your daughter's school district is, but if she's submitting any papers via course management systems (Blackboard, WebCT, ANGEL, etc.), she may be instructed by her teachers to use Word only (despite any obvious compatibilities to the contrary).
I just bought an
HP 1020 recently -- 2500 pages per cartridge (and only $60 per replacement cartridge), and about 15 pages a minute. The quicker she can print, the quicker she can get to writing the next draft.
What a wonderful, responsible parent you sound like. Will you parent some of my students? 'Cause I guarantee you
nobody's reading their papers before they hand them to me.
If they hand them to me.
EDIT: I should have mentioned that the HP 1020 is supposedly not Mac compatible. But it works just fine with the HP 1022 driver, which you can get
here.
