The answer really depends on what the business centre facilities are. Some printers have "Airdrop", and others I have used have an email address for the printer, so you just address it to that device to make it print.

As others have said, a thumb drive to the printer - although I would be more wary of using it on a shared computer to avoid infection.

Most hotels have allowed me to email the reception who then have printed out the single page etc.
