Hello All
I Built a form to act as my report layout to print using JavaFX8 Lib, and I am printing in a USB windows POS printer.

It has no standard paper size,like A4, A5, etc, instead it used a 80mm X user defined length

I can print everthing correctly with the execption of the margins.
I am getting huge margins when i should get 0. is there a way to set 0 margins so it prints the form near to the paper margin ?

Any Ideas ?

I have done some more experiments and I always get an error.
Can anyone help, please

my code:

B4X:
    PrintForm.Initialize("PrintForm", 200,200)
    PrintForm.RootPane.LoadLayout("ticket") 'Load the layout file.
    printer_label_pax.text=CurRnd
    'printer_datetime.text = $"${datetime.date(datetime.now)} - ${datetime.time(datetime.now)}"$
   
    Dim PP As Paper
    PP.Initialize()
   
    Dim PC As Printer
    PC.Initialize()
   
    Dim PL As PageLayout
    PL.Initialize()
   
    PP = Paper_static.A6
    PC = Printer_Static.GetDefaultPrinter
    PL = PC.CreatePageLayout2(PP, PageOrientation_Static.PORTRAIT, "HARDWARE_MINIMUM")
   
    Dim PJ As PrinterJob
    PJ = PrinterJob_Static.CreatePrinterJob2(PC) 'CreatePrinterJob
    PJ.PrintPage2(PL, PrintForm.RootPane)
    PJ.EndJob
the error in the log:
