I'm a tutor, I help people make use of their computers/tablets/phones etc...
Many of my learners benefit from step-by-step instructions on simple stuff like turn the computer on, start the internet, close everything and start again.
I keep finding it a criminal waste of time getting a couple of sheets printed when I'm on-site!
I've seen very efficient office admins using portable printers but I have ZERO knowledge on them!
Any recommendations or advice on what to expect?
