The device is constantly buggy, it works with a flash drive every other time and it's not about the flash drive, because with it, a similar device in the stolitsa shopping center works perfectly. The second one is set up somehow so that it cannot be sent from different devices to print at the same time, because due to the fact that someone out of turn sends everything to print via Wi-Fi, everything is buggy.
They won't let me in, I tried to get to the device in a mask and gloves twice (with a period of 3 months). But the persistent janitor does not let her into any.
