Chrome window opened by Cypress keeps asking to add printer

Current behavior

I have a printer in my wifi network. Every time I run a Cypress test locally, the Chrome instance Cypress opens to run the tests in shows a notification whether I want to add the newly found printer in my network to Google Cloud Print. This gets quite annoying after some time.

Desired behavior

Deactivate the Google features of Chrome and prevent the notification from showing up by default as it isn’t necessary for test execution.

Steps to reproduce

Add a printer to your network, npm run cypress:open and run any test locally.

Versions

Cypress v2.1.0 Chrome v65 Mac OS v10.13.4

I believe that the --disable-device-discovery-notifications Chromium flag may silence these notifications.

Could you try adding this to your cypress/plugins/index.js file and let me know if this works?

module.exports = (on, config) => {
  on('before:browser:launch', (browser = {}, args) => {
    if (browser.name === 'chrome') {
      args.push('--disable-device-discovery-notifications')
      return args
    }
  })
}

If this works, we can very easily automatically do this in Cypress when launching Chrome.
