Java获取配置打印机，并（佳博打印机）打印小票
因项目需求，需要打印类似超市的收银小票。
贴上代码，以供记录和参考。
一：获取电脑本地所有的打印服务。
@RequestMapping("/getPrint")
@ResponseBody
public Object getPrint(){
PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.BYTE_ARRAY.PNG;
PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor,printRequestAttributeSet );
//获取打印机列表
List<String> printList = new ArrayList<>();
for (int i = 0;i<printService.length;i++){
printList.add(printService[i].getName());
}
return new ReportResponse(printList);
}返回结果：
{
"header": {
"code": "200",
"memo": "success"
},
"result": [
"Microsoft XPS Document Writer",
"GP-U80250 Series",
"Fax"
]
}二：打印小票。
1：配置打印机
public class Printer {
private SalesTicket salesTicket;
public Printer(SalesTicket salesTicket) {
this.salesTicket = salesTicket;
}
public void printer(String printerName) {
//Book 类提供文档的表示形式，该文档的页面可以使用不同的页面格式和页面 painter
//要打印的文档
Book book = new Book();
//PageFormat类描述要打印的页面大小和方向
//初始化一个页面打印对象
PageFormat pf = new PageFormat();
//设置页面打印方向，从上往下，从左往右
pf.setOrientation(PageFormat.PORTRAIT);
//设置打印纸页面信息。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();
MediaSize mediaSize = new MediaSize(80, 3276, MediaPrintableArea.MM);
//paper.setSize(200,30000);// 纸张大小
//paper.setImageableArea(0,0,200,30000);// A4(595 X 842)设置打印区域，其实0，0应该是72，72，因为A4纸的默认X,Y边距是72
paper.setSize((double) mediaSize.getX(25400) * 72.0D, (double) mediaSize.getY(25400) * 72.0D);
paper.setImageableArea(0.0D, 0.0D, paper.getWidth(), paper.getHeight());
pf.setPaper(paper);
book.append(salesTicket, pf);
HashAttributeSet hs = new HashAttributeSet();
hs.add(new PrinterName(printerName, null));
PrintService[] pss = PrintServiceLookup.lookupPrintServices(null, hs);
if (pss.length == 0) {
throw new ServiceException(ErrorCodes.PRINTER_NOTHAVE);
}
//获取打印服务对象
PrinterJob job = PrinterJob.getPrinterJob();
//设置打印类
job.setPageable(book);
try {
// 添加指定的打印机
job.setPrintService(pss[0]);
// 打印执行
job.print();
} catch (PrinterException e) {
throw new ServiceException(ErrorCodes.PRINTER_ERROR);
}
}
}2：配置小票格式以及数据
public class SalesTicket implements Printable {
private List<GoodsInfoPo> goods;
private List<PayTypePo> payTypePos;
private String deptNum;
private String orderNum;
private Integer peopleCount;
private String orgName;
private String turntableInfo;
private Long orderPeopleNum;
private String orderPeopleName;
private String openTime;
private String payTime;
private Integer payCount;
private Double shouldPayAmount;
private Double truePayAmount;
private Double discountAmount;
private SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss EEE");
public SalesTicket(List<GoodsInfoPo> goods, List<PayTypePo> payTypePos, String deptNum, String orderNum, Integer peopleCount, String orgName, String turntableInfo, Long orderPeopleNum, String orderPeopleName, String openTime, String payTime, Integer payCount, Double shouldPayAmount, Double truePayAmount, Double discountAmount) {
super();
this.goods = goods;
this.payTypePos = payTypePos;
this.deptNum = deptNum;
this.orderNum = orderNum;
this.peopleCount = peopleCount;
this.orgName = orgName;
this.turntableInfo = turntableInfo;
this.orderPeopleNum = orderPeopleNum;
this.orderPeopleName = orderPeopleName;
this.openTime = openTime;
this.payTime = payTime;
this.payCount = payCount;
this.shouldPayAmount = shouldPayAmount;
this.truePayAmount = truePayAmount;
this.discountAmount = discountAmount;
}
@Override
public String toString() {
return "SalesTicket{" +
"goods=" + goods +
", payTypePos=" + payTypePos +
", deptNum='" + deptNum + '\'' +
", orderNum='" + orderNum + '\'' +
", peopleCount=" + peopleCount +
", orgName='" + orgName + '\'' +

", payTime='" + payTime + '\'' +
", payCount=" + payCount +
", shouldPayAmount=" + shouldPayAmount +
", truePayAmount=" + truePayAmount +
", discountAmount=" + discountAmount +
'}';
}
/**
* 打印方法
* graphics - 用来绘制页面的上下文，即打印的图形
* pageFormat - 将绘制页面的大小和方向，即设置打印格式，如页面大小一点为计量单位（以1/72 英寸为单位，1英寸为25.4毫米。A4纸大致为595 × 842点）
* 小票纸宽度一般为58mm，大概为165点
* pageIndex - 要绘制的页面从 0 开始的索引 ，即页号

switch (pageIndex) {
case 0:
return PAGE_EXISTS;
default:
return NO_SUCH_PAGE;
}
}
}3：实现接口：
@RequestMapping("/printReport")
@ResponseBody
public Object testPrint(@Validated @RequestBody PrintFrom printFrom){
Map<String,Object> map = new HashMap<>(1);
List<PrintContentPo> printContentPoList = printMapper.getPrintContent(printFrom);
for (PrintContentPo printContentPo:printContentPoList){
List<GoodsInfoPo> goods = printGoodsMapper.getPrintGoods(printContentPo.getPayId());
List<PayTypePo> payTypePos = printPayTypeMapper.getPayTypeList(printContentPo.getPayId());
for (GoodsInfoPo goodsInfoPo:goods){
if (goodsInfoPo.getIsCombo().equals(ComboType.COMBO.getCode())){
List<PrintGoodsComboPo> comboPoList = printGoodsComboMapper.getGoodsCombo(printContentPo.getPayId(),goodsInfoPo.getBarConfigId());
goodsInfoPo.setPrintGoodsComboPoList(comboPoList);
}
}
SalesTicket stk=new SalesTicket(goods,payTypePos,printContentPo.getDeptNum(),printContentPo.getOrderNum(),printContentPo.getPeopleCount(),printContentPo.getOrgName(),printContentPo.getTurntableInfo(),printContentPo.getOrderPeopleNum(),printContentPo.getOrderPeopleName(),printContentPo.getOpenTime(),printContentPo.getPayTime(),printContentPo.getPayCount(),printContentPo.getShouldPayAmount(),printContentPo.getTruePayAmount(),printContentPo.getDiscountAmount());
Printer p=new Printer(stk);
p.printer(printFrom.getPrinterName());
map.put("result","success" );
}
return new ReportResponse(map);
}4：注意事项：
主要实现方法就这些。
实体类，mapper和sql就不展示了。
另外，设置小票格式根据自己的需求配置。
谢谢！
