Home printers may be installed on school Windows computers IF it can be done without installing the printer software package. Printer software often adds extra services (slowing down the computer) as well as changing the way the computer handles media files. You cannot install printers on Chromebooks, but here are options for home print with those.
For best results:
1) Plug the printer in with a USB cable. Windows will install most printers automatically.
2) If it is a wireless printer, use "Add Printer" (in Devices & Printers) to search for the printer. Depending on the home network setup, this may or may not work correctly.
If a download is necessary, you should first check with HelpDesk or Mr. Hall to make sure you use the "Driver Only" installer and not the complete software package.
