Your Chromebook is a great little device, but you've probably noticed that you can't connect to just any printer. Chromebooks can't download software, which means that printer drivers can't be installed, so you can't connect via USB. So what can you do?
All Chromebooks can print to a "Cloudprint" wifi-enabled printer. It takes a bit of setup and about 20-30 minutes. However, once you've set it up to print via your home network, it works pretty well. If the links provided don't provide enough guidance, you may need to consult the help guides for your specific model of printer.
If you don't have a Cloudprint-ready printer or don't want to tackle the setup, the easiest solution would be for your child to log in to their @mylcusd.net Google account on your home computer (that's connected to your printer), and print from there.
For our students' safety, we limit who they can email and share Google Docs with--up through 10th grade, students can only email within the LCUSD domain, so students can't email or share docs with parents for printing.
