Print

@Alexandre-Venditti69 well you put the image on the screen by using a url ,

<img src="url...",

so there u have the url u need to use to print

u may have to extract it again from the html content at the time of the print request,
but u can use the dhtml API calls to get it, or jQuery

if u add a known ID= to the img tag

document.getElementById(…)
then u can get the value of the src=

[Alexandre-Venditti69]

@sdetweil i think if you use that, then u would have to add code to that to get to the image…
Of course, bugsounet told me i ve have to add console.log(payload) on the notification.
i ve start to write a new fonction in Ext-Selfies.js, and his node_helper.
texte du lien this exemple script print on défaut printer , but how i can writte it to resolve the payload

[sdetweil]

@Alexandre-Venditti69 console.log(notification)
will dump out the structure of the notification object so u might find the url there

@sdetweil

showLastPhoto: function(result, sendResult = true, showLastOnly = false) {
    var autoValidate = showLastOnly ? true : result.options.autoValidate
    this.IsShooting = true
    var con = document.querySelector("#EXT-SELFIES")
    con.classList.add("shown")
    var rd = document.querySelector("#EXT-SELFIES .result")
    rd.style.backgroundImage = `url(modules/EXT-Selfies/photos/${result.uri})`
    rd.classList.add("shown")
    if (autoValidate) {
      if (this.config.usePreview) {
        var preview = document.querySelector("#EXT-SELFIES .preview")
        preview.classList.remove("shown")
      }
      setTimeout(()=>{
        this.lastPhoto = result
        if (sendResult) this.sendNotification("EXT_SELFIES-RESULT", result)
        this.closeDisplayer()
      }, this.config.resultDuration)
    }
  },

  validateSelfie: function(result) {
    var preview = document.querySelector("#EXT-SELFIES .preview")
    preview.classList.remove("shown")
    var pannel = document.getElementById("EXT-SELFIES-PANNEL")
    pannel.classList.add("shown")

    var sendIcon = document.getElementById("EXT-SELFIES-SEND")
    sendIcon.onclick = ()=> {
      this.lastPhoto = result    // Sauvegarde le selfie en local
      this.sendNotification("EXT_SELFIES-RESULT", result) // Envoi la notif pour EXT-SSender
      this.closeDisplayer()
    }

Dans cette partie, j’ai rajouté à SendIcon :

this.sendSocketNotification("printResult", payload)

Mon node helper reçoit cette notification et exécutera printResult  function (payload) {}

Est ce un bon début ?

@sdetweil thanks for your intention 🙏🏼

[Alexandre-Venditti69]

@sdetweil I read the print.js library, it is of substantial size, does such a volume remain “compatible” with a simple raspberry?

[sdetweil]

@Alexandre-Venditti69 no clue… raspberry pi 3 has 1 gig or memory and pi4 can have up to 8gig.

sorry, I have no idea.
I would have thought u could print directly from the browser, and not have to go to the helper.

never tried printing
