java - pos打印机CUP服务器Ubuntu 16的打印问题

Question

我在Ubuntu 16上安装了cups服务器，安装了POS打印机后，经过测试测试页和lpr命令行命令，工作正常；在java中使用PrintJob，java找到打印机，但没有打印机任何东西....

解决这个问题的一些想法？

我前段时间也遇到过同样的问题，我这样做了，也许可以帮助你。让我知道。

public static boolean imprimirDocto(String documentPath, String printerName) {
        File f = new File(documentPath);
        try {
            PDDocument doc = PDDocument.load(f);

            PrinterJob pj = PrinterJob.getPrinterJob();

            PrintService[] ps = PrintServiceLookup.lookupPrintServices(null, null);
            PrintService printService = null;
            if (ps.length > 0) {
                //This searchs for all the printers, and looks for the 'printerName'
                for (int i = 0; i < ps.length; i++) {
                    System.out.println("Printer name: " + ps[i]);
                    if (ps[i].getName().toLowerCase().contains(printerName.toLowerCase())
                            || ps[i].getName().contains(printerName)) {

                        printService = ps[i];

                        System.out.println("Setting the printer...");
                        pj.setPrintService(printService);
                        i = ps.length;
                    }
                }

                pj.setPageable(new PDFPageable(doc));
                pj.print();

                return true;

            } else {
                return false;
            }

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return false;
        }
    }
