Sounds all to familiar
I remember when I was a lowly help desk bod. We bought new printers from a well known company which has a large research arm in America somewhere
New printers! Scan, fax, print, fast, A3, A4 and A5! Yummy!
After the engineer attempted to install the first printer, I told him I wasn't going to allow him to install the rest and risk leaving the company with no high capacity printing, and that I would do it instead. I un-boxed every machine, wheeled them around the buildings, opened every machine and connected the power supply board to the rest of the printer, upgrade the BIOS, faff around with drivers, and then get them all working with our fax software (which wasn't fun)
They worked OK after that
