B4J Question How to print on thermal paper jfx8print

[Reminisce]

Hello, I want to be able to get the height of nodes on this panel and print this panel on a thermal printer paper. It is an invoice for a restaurant menu.

Dim pnlheight As Int = 0
    
    
    For Each v As B4XView In pnlprint.GetAllViewsRecursive
            
        If v  Is CustomListView Or v Is Label Or v Is ImageView Then
            pnlheight = pnlheight +  v.Top + v.Height
        End If
    Next
    
    Log(pnlheight&"pnlheight")
    'clvtoprint.AsView.Height= pnlheight
    pnlprint.Height = pnlheight

The code above, doesn't set the correct height.

    Dim pj As PrinterJob = PrinterJob_Static.CreatePrinterJob
    pj.ShowPageSetupDialog(Null)
    pj.PrintPage(pnlprint)
    pj.EndJob

hello!
maybe this link will help you..

B4j Print JavaFX8

Here is a B4j library written in B4j to access the full Printer modules provided with JavaFX8. Full source code is available. At it's simplest, you can print a node using: Dim P As Printer = Printer_Static.GetDefaultPrinter Dim PJ As PrinterJob = PrinterJob_Static.CreatePrinterJob2(P)...

what i can say is that in my case i had to construct an html ( with the data that i needeed) and then print it.

Thank you, creating an html in my case would be an overkill. I just want to adjust the panel's height to fit the items and send it to a particular thermal printer 🖨..

Thanks, i fixed it already, i created a variable that summed the height of individual nodes. Then i did..

Pnlprint.height = allheight + 5dip

I Reminisce have the same problem could you show an example of how to add the nodes ☹☹

Just loop through the views on the CLV, and get the individual height inside the loop, create a variable that adds each of this height inside the loop.

Finally, set your panel height to the variable and maybe add some dip to it.. Like in my example above.
