Most of us have home computers to format our job applications. I don't have a home printer, but I haven't printed a job application for nearly a decade; they have all been electronic submissions. Also, I use a personal email account and mobile phone rather than my current employer's when applying for a new job. It's easy and sensible to keep job applications separate from employer's equipment.
These days I'm getting contacted by via LinkedIn about job offers even though I'm not looking. The lack of privacy with LinkedIn is a concern.
