webContents.print() doesn't work under Windows when 'deviceName' is provided

[gozzoo]

• Electron Version 4.0.7
• Operating System Windows 10 32 bit
• Last known working Electron version 3.1.3

Expected Behavior

webContents.print() should send print a job to the specified printer

Actual behavior

Nothing happens. Callback gets called much latter, for example on program exit.

printToPDF works though.

To Reproduce

let deviceName = 'HP LaserJet 1020'
let options = {deviceName, silent: true}
win.webContents.print(options, (err) => {
  if (!err)
    console.error('printing failed')
})

@gozzoo the options param you sent to webContents.print() is false.

It should be: let options = { deviceName: deviceName, silent: true }.

@popod my example seems to be correct.

Just to make sure I run this in node:

let deviceName = 'HP LaserJet 1020'
let options = {deviceName, silent: true}
console.log(options)

and the output is this:

{ deviceName: 'HP LaserJet 1020', silent: true }

It's called 'Shorthand property names' and was introduced in ES2015.

Anyways I just checked my actual code and it is:

  win.webContents.print({deviceName: 'HP LaserJet 1020'}, (err) => ... )

@gozzoo yes, my bad ! your code seems to be correct :)

I'm having problems with webContents.print() too..

I have the same issue.

Can confirm printing is working as intended on Electron 3.1.6

(Win 10 64 bits)

[shabeer-mdy]

it's work fine but I change the default printer settings portrait to landscape then it prints as portrait, why this happening?

i am too facing same issue. Any update till when this will be resolved. i have to use old version of electron because of this.

This is working correctly when just deviceName is provided: the root cause of this issue you're experiencing is the silent print, which I'm investigating separately and which there exist other issues for.
