Sending data to a printer in Java
提问by Andrew Lynch
The code below sends data to a printer however, while it reaches the printer queue it comes back with a Unable to convert PostScript file.I thought that this would be overcome by specifying the flavor but this is not the case
下面的代码将数据发送到打印机，当它到达打印机队列时，它返回一个Unable to convert PostScript file.我认为这可以通过指定风味来克服，但事实并非如此
import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintException;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;
import javax.print.attribute.PrintServiceAttribute;
import javax.print.attribute.standard.PrinterName;
public class New1 {
public static void main(String[] args) {
try {
String s = "Hello";
// byte[] by = s.getBytes();
DocFlavor flavor = DocFlavor.STRING.TEXT_PLAIN;
PrintService pservice = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob job = pservice.createPrintJob();
Doc doc = new SimpleDoc(s, flavor, null);
job.print(doc, null);
} catch (PrintException e) {
e.printStackTrace();
}
}
}

Using only JPS you will have problems with Mac. My suggestion is use Java 2 Print API + Java Print Service.
仅使用 JPS 会在 Mac 上出现问题。我的建议是使用 Java 2 Print API + Java Print Service。
Java 2 Print API is something like 1990 style. To avoid to create your code using Java 2 Print API you could use PDFBox http://pdfbox.apache.orgas a framework.
Java 2 Print API 有点像 1990 风格。为避免使用 Java 2 Print API 创建代码，您可以使用 PDFBox http://pdfbox.apache.org作为框架。
With PDFBox you could create a PDF document (http://pdfbox.apache.org/1.8/cookbook/documentcreation.html) but instead of save, print it using that code:
使用 PDFBox，您可以创建一个 PDF 文档（http://pdfbox.apache.org/1.8/cookbook/documentcreation.html），但不是保存，而是使用该代码打印它：
PrinterJob printJob = PrinterJob.getPrinterJob();
PrintService service = PrintServiceLookup.lookupDefaultPrintService();
printJob.setPrintService(service);
document.silentPrint(printJob);
It works fine in my Mac.
它在我的 Mac 上运行良好。
