You’ve nothing to worry about. If they’re still in the sealed packages, then no harm was done at all, just wait a few hours for them to warm up to room temperature so they don’t get any condensation moisture on or in them when you open them. If they weren’t in sealed packaging, once they warm up for a few hours and any condensation moisture is evaporated, they’ll work like nothing happened too. I do it all the time with toner cartridges I carry around for troubleshooting or just transporting from one site to another.

Just give everything time to warm up before you start unpacking and running and you’ll be fine.

Best of luck & enjoy your new printer.
