我在双面打印机上以横向模式打印 JasperReports 报告。在此,我将支持PCL5和PCL6打印驱动程序。
在互联网上搜索时,我发现了以下代码片段来完成这项工作:
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.print.Book;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import java.awt.print.PrinterException;
import java.awt.print.PrinterJob;
import javax.print.PrintService;
import javax.print.attribute.HashPrintRequestAttributeSet;
import javax.print.attribute.PrintRequestAttributeSet;
import javax.print.attribute.standard.OrientationRequested;
import javax.print.attribute.standard.Sides;
public class PrintingTest {
public static void main(String[] args) {
try {
//This are for configuration purpose
String orientation = "LANDSCAPE";
String duplexMode = "LONG_EDGE";
int pageOrientation = 0;
PrintRequestAttributeSet atr = new HashPrintRequestAttributeSet();
if ("Landscape".equals(orientation)) {
atr.add(OrientationRequested.LANDSCAPE);
pageOrientation = PageFormat.LANDSCAPE;
} else if ("Reverse_Landscape".equals(orientation)) {
atr.add(OrientationRequested.REVERSE_LANDSCAPE);
pageOrientation = PageFormat.REVERSE_LANDSCAPE;
} else {
atr.add(OrientationRequested.PORTRAIT);
pageOrientation = PageFormat.PORTRAIT;
}
if ("LONG_EDGE".equals(duplexMode)) {
atr.add(Sides.TWO_SIDED_LONG_EDGE);
} else {
atr.add(Sides.TWO_SIDED_SHORT_EDGE);
}
//Printing to the default printer
PrintService printer = javax.print.PrintServiceLookup
.lookupDefaultPrintService();
//Creating the printing job
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setPrintService(printer);
Book book = new Book();
PageFormat pageFormat = printJob.defaultPage();
pageFormat.setOrientation(pageOrientation);
// Appending a exampledocument to the book
book.append(new ExampleDocument(), pageFormat);
// Appending another exampledocument to the book
book.append(new ExampleDocument(), pageFormat);
// Setting the Pageable to the printjob
printJob.setPageable(book);
try {
// Here a could show the print dialog
// printJob.printDialog(atr);
// Here I pass the previous defined attributes
printJob.print(atr);
} catch (Exception PrintException) {
PrintException.printStackTrace();
}
} catch (PrinterException ex) {
ex.printStackTrace();
}
}
public static final int MARGIN_SIZE = 72;
private static class ExampleDocument implements Printable {
public int print(Graphics g, PageFormat pageFormat, int page) {
Graphics2D g2d = (Graphics2D) g;
g2d.translate(pageFormat.getImageableX(),
pageFormat.getImageableY());
// Only on the first two documents...
if (page <= 1) {
// Prints using one inch margin
g2d.drawString("Printing page " + page + " - duplex...",
MARGIN_SIZE, MARGIN_SIZE);
return (PAGE_EXISTS);
}
return (NO_SUCH_PAGE);
}
}
}
这在 PCL6 上工作正常,但是,当在 PCL5 上测试时,我注意到LONG_EDGE和SHORT_EDGE规则被简单忽略。在这两种情况下,作业都以 LONG_EDGE 的形式发送。这不会是一个问题,除了 Java AWT 打印API通过逆时针旋转所有页面90º来解决横向打印,从而导致它在 SHORT_EDGE 模式下打印。 / p>
Obs:通过使用 SWT API SHORT_EDGE 和 LONG_EDGE 两种配置正确打印>。但是我无法在 SWT 兼容的打印请求中转换碧玉打印请求。
我的问题是:有没有人遇到过这种情况?给出了哪种解决方案?
根据我的观察,我发现了这些可能的解决方案:
不是让 AWT 转动页面并发送纵向打印请求,而是强制它将其作为横向打印请求发送;
找到一种方法,当页面处于横向模式时,反转 LONG_EDGE 和 SHORT_EDGE 命令。请注意,对于这一点,我有义务纠正两者都被视为 LONG_EDGE 请求的问题。
转换 JasperReports 以使用 SWT 打印 API 。
答案 0 :(得分:1)
不确定它有用但我6年前遇到过这个问题,唯一的解决方案是使用打印机(Xerox)功能通过.xpf文件接收打印指令。例如:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xpif SYSTEM "xpif-v02012.dtd">
<xpif cpss-version="2.01" version="1.0" xml:lang="en">

<requesting-user-name syntax="name" xml:space="preserve">domain user</requesting-user-name>
</xpif-operation-attributes>
<job-template-attributes>
<copies syntax="integer">1</copies>
<finishings syntax="1setOf">
<value syntax="enum">3</value>
</finishings>
<job-recipient-name syntax="name" xml:lang="en-US" xml:space="preserve">domain user</job-recipient-name>
<job-save-disposition syntax="collection">

与需要打印的文件一起发送到打印机。
