Error " settings to access the printer '"' are not valid."

I have an application ASP.Net MVC that makes product sale and printing of this sale we work with several brands of thermal printers (not tax) such as: Tanca, Bematech, Epson, among others.. we use to print the windows spooler, however, recently the customer bought a computer that already comes with the printer integrated into it.. when we send the print of the sale the following error occurs: "The settings to access the 'CUSTOM_IMPRESSORA' printer are not be."

We are doing the printing as follows:

    public void impressaoVenda(VendaModel venda, String itens)
    {
        PrintDocument printDoc = new PrintDocument();
        PrintController printController = new StandardPrintController();
        printDoc.PrintController = printController;

        PaperSize paperSize = new PaperSize("BOBINA", 800, 999999);
        printDoc.DefaultPageSettings.PaperSize = paperSize;
        printDoc.PrinterSettings.DefaultPageSettings.PaperSize = paperSize;

        String nomeImpressora = venda.Funcionario_Logado.Impressora;

        int vias = 1;

        printDoc.PrinterSettings.PrinterName = nomeImpressora;
        printDoc.DocumentName = "Cupom";

        this.itens = itens;
        this.venda = venda;

        printDoc.PrintPage += new PrintPageEventHandler(this.PrintPageVenda);
        printDoc.Print();

        limparObjetosImpressao();
    }

The error occurs in the following Line:

    printDoc.Print(); 

Do not reach or enter the method.

Has anyone been through this?
