2018年写了一个标签打印机(TSC TX600)，标签打印程序，实现功能是通过串口读出设备ID生成二维码和设备信息，用于esp8266 smart config配网。源码和资料：https://download.csdn.net/download/u012854263/12080191 package com.aiyun.print; import java.awt.print.Book; import java.awt.print.PageFormat; import java.awt.print.Paper; import java.awt.print.PrinterException; import java.awt.print.PrinterJob; import java.io.File; import java.util.HashMap; import java.util.Map; import javax.print.Doc; import javax.print.DocFlavor; import javax.print.DocPrintJob; import javax.print.PrintService; import javax.print.PrintServiceLookup; import javax.print.SimpleDoc; import javax.print.attribute.HashPrintRequestAttributeSet; import javax.print.attribute.PrintRequestAttributeSet; import javax.print.attribute.standard.Copies; import com.google.zxing.BarcodeFormat; import com.google.zxing.EncodeHintType; import com.google.zxing.MultiFormatWriter; import com.google.zxing.common.BitMatrix; public class PrintLabel { public static void CreateQRCode(String content, String path, String fileName) { // 二维码生成 MultiFormatWriter multiFormatWriter = new MultiFormatWriter(); Map hints = new HashMap(); hints.put(EncodeHintType.CHARACTER_SET, "UTF-8"); hints.put(EncodeHintType.MARGIN, 0); BitMatrix bitMatrix = null; try { File file = new File(path, fileName + ".jpg"); bitMatrix = multiFormatWriter.encode(content, BarcodeFormat.QR_CODE, 17, 17, hints); MatrixToImageWriter.writeToFile(bitMatrix, "jpg", file); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } public static void PrintInit(String ID, String QRCodeName1) throws PrinterException { // 通俗理解就是书、文档 Book book = new Book(); // 设置成竖打 PageFormat pf = new PageFormat(); pf.setOrientation(PageFormat.PORTRAIT); // 通过Paper设置页面的空白边距和可打印区域。必须与实际打印纸张大小相符。 Paper paper = new Paper(); // 1点为1英才的1/72，1英寸为25.4毫米。A4纸大致为595×842点 // A4纸的尺寸是209*296 点数是209/25.4*72=593 296/25.4*72=839 //85 57 // ------新版本标签规格 30*20--------- int label_width_new = 85; int label_height_new = 57; paper.setSize(label_width_new, label_height_new); paper.setImageableArea(0, 0, label_width_new, label_height_new);// 设置打印范围 // ------旧版本标签规格 35*25--------- // int label_width_old = 100; // int label_height_old = 70; // paper.setSize(label_width_old, label_height_old); // paper.setImageableArea(0, 0, label_width_old, label_height_old);// 设置打印范围 // 设置打印配置 pf.setPaper(paper); // 添加打印类 QRCodeInfo qrcode = new QRCodeInfo(ID, QRCodeName1); book.append(qrcode, pf); // 设置打印数据的格式，此处为图片gif格式 DocFlavor psInFormat = DocFlavor.INPUT_STREAM.GIF; // 设置打印属性 PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(new Copies(1));// 打印份数 // 查找所有打印服务 PrintService[] services = PrintServiceLookup.lookupPrintServices(psInFormat, aset); // 将所有查找出来的打印机与自己想要的打印机进行匹配，找出自己想要的打印机 PrintService myPrinter = null; for (int i = 0; i < services.length; i++) { // System.out.println("service found: " + services[i]); String svcName = services[i].toString(); if (svcName.contains("TSC TX600")) { // 指定打印机 //if (svcName.contains("AYZN_Print")) { // 指定打印机 //if (svcName.contains("ZMIN X1i")) { // 指定打印机 System.out.println("OK"); myPrinter = services[i]; } } // 获取打印服务对象 PrinterJob job = PrinterJob.getPrinterJob(); // 获取打印服务对象 if (myPrinter != null) { try { job.setPrintService(myPrinter); // 设置打印类 job.setPageable(book); // 打印 // System.out.println("--》打印数据"); job.print(); } catch (Exception pe) { pe.printStackTrace(); } } else { System.out.println("no printer services found"); } } }
