QUESTION :
I have a Linux computer with HP printer connected through USB. While my friend who lives elsewhere has a Windows 7 laptop.
I would like to share my printer with him due to some important work. Is it possible to share printer over the internet in this cross-platform environment?
ANSWER :
So here is one method you could use, it is Google Cloud Print, this allows you to add a printer from Chrome Settings that you have connected to your computer and then you can then share this printer using Google to your friend
Here is a step by step instruction: http://www.laptopmag.com/articles/how-to-set-up-google-print-on-your-chromebook
Quick and Dirty of it:
Open Chrome, go to Settings > Advanced Settings, Click Add
Printers (Might be labeled “Manage”, it was on mine)
Click Add Printers on the Next Page
Click on the Printers you want to Add
Click Manage your printers
Select a Printer and Click Share
Send it to your friend
This should allow your friend to access the printer using Chrome
There is also a Google Cloud Print Driver that should allow access to the printer from any application. Printer Driver Download
EDIT: I just went through all these steps myself just now to verify it work, Update Answer with the steps I took. I verified that this does work.
