In general, the first paycheck from a new employer is usually an actual paper check, because they want you to get your 1st payment before the direct deposit is set up.

I've even been given a pro-rated paper check from the accounting department on the first day (as part of onboarding), for 1st day wages, as soon as I get into the office and shown to my desk/work area.

It's an act of good will because they are paying you for work you did on your first day (instead of cheating you to say "we'll pay you when everything gets set up", they are upfront with the "day worked deserves fair wage" principle)
