Once you have wi-Fi it's easy enough I think, I have an app epson iprint which allows me to print to my epson printer. Printer needs to be a wifi one though too. Alternatively work coud be emailed to teacher who could print then if needed.
I too have a pupil who uses a Neo2 (he's dyslexic & dyspraxic). It's rugged, basic and dull enough to be secure! It saves everything automatically to one of 8 files.
An ipad would be more flexible though, if it's more an issue of the barrier between brain and paper. She could write, draw, mind map notes... and she can only play if it has games on it. Something like Popplet maybe?
I have had a student with dyspraxia use one of these Neo2 to type written assignments which were then printed, if that's of any help. It was durable enough, made for being transported around in a schoolbag. Although if it has been recommended that your child use a laptop then the school should try and facilitate that. Perhaps an iPad would be useful, you can get very sturdy cases for them and you can lock it so that there is only access to whatever apps/note taking software needed for school.
Agree and if you have an EP and/or OT report to back up the recommendations so much the better. Do they stay in one room by in large or move around lot ? Laptop use could be an issue otherwise and she needs to be able to touch type first.
Go into school and meet with SENCO and teacher to discuss IEP, bring suggestions of items that might help including how they can be used. Tell them you will provide them if they will work with them and to get back to you with their plan.
