我尝试使用IPP(Internet打印协议)在第二个纸盘上打印文档。我正在使用此npm IPP-Library

但是在任何时候我尝试打印文档时,我的打印机都会显示一条消息,说明我需要在第一个纸盘和控制台输出中添加纸张Printed: successful-ok

var ipp = require("ipp");
var PDFDocument = require("pdfkit");
var concat = require("concat-stream");

var doc = new PDFDocument;
doc.text("Hello World");

doc.pipe(concat(function (data) {
    var printer = ipp.Printer("MY_URL");

    var file = {
        "operation-attributes-tag": {
            "requesting-user-name": "admin",
            'attributes-charset': 'utf-8',
            'attributes-natural-language': 'de'
        },
        "printer-attributes": {
            "media-col": {
                "media-source": "tray-2"
            },
        },
        data: data
    };
    printer.execute("Print-Job", file, function (err, res) {
        console.log("Printed: " + res.statusCode);
    });
}));

doc.end();

我尝试的其他变体是(来自here):

var PDFDocument = require("pdfkit");
let fs = require('fs')
var ipp = require('ipp');
var uri = "http://10.1.205.71";


var msg = new Buffer(
  '0200'+ //Version
  '000201e6d5f2'+
  '01'+ //Operation attributes tag (your information in the Operation attributes might be different)
    '47'+ //charset tag

      '747261792d32'+ //tray-2
    '37'+ //end of collection
    '00000000'+ //name length and value length
  '03', 'hex');

var doc = new PDFDocument;
doc.text("Hello World");

var buffers = [];
doc.on('data', buffers.push.bind(buffers));
doc.on('end', function(){
  var buf = Buffer.concat(buffers);
  var catBuf = Buffer.concat([msg, buf]);
  ipp.request(uri, catBuf, function(err, res){
    if(err){
      return console.log(err);
    }
    console.log(JSON.stringify(res,null,2));
  });
});
doc.end();

但后来我收到了这条错误消息:

我的打印机不支持IPP,但我在Macbook上共享它,它为所有共享打印机提供IPP服务。 如果我正在使用第一个纸盘并且纸上有一切都很好,但对于我的项目,也需要在其他纸盘上打印。

属性&#39;从Get-Printer-Attributes列表和其他托盘中返回的列表第二篇论文支持media-source,但 第一个纸盘工作。

有谁知道如何在另一个纸盘上成功打印?

更新:我还尝试了另一台打印机,但我遇到了同样的错误。

更新22.06.17:它仍然很困惑,并且没有任何线索如何解决这个问题。

this pull request似乎可以解决您遇到的问题。在ipp的作者合并拉取请求之前,您可以通过在项目目录中运行以下命令来更新npm包以指向该补丁:

npm i --save ipp@github:jaymcaliley/ipp

答案 1 :(得分:0)

对您发送的请求的响应,状态代码为400,发送给打印机的请求。

这可以在on line 30看到。

这可能是由防火墙配置或错误的网络设置引起的。

您需要在此示例中正确指定打印机的URL,并检查此URL是否有效以及打印机是否响应它:

  var printer = ipp.Printer("http://NPI977E4E.local.:631/ipp/printer");

自从我求助以来已经有一段时间了。感谢所有人的贡献=)

我从这里和Github尝试了所有建议的解决方案,但它们都没有奏效,但我找到了解决问题的解决方案。

var ipp = require("ipp");
var PDFDocument = require("pdfkit");
var concat = require("concat-stream");

var doc = new PDFDocument;
doc.text("Hello World");

doc.pipe(concat(function (data) {
    var printer = ipp.Printer("MY_URL");

    var file = {
        "operation-attributes-tag": {
            "requesting-user-name": "admin",
            'attributes-charset': 'utf-8',
            'attributes-natural-language': 'de'
        },
        "printer-attributes": {
            // OLD WAY WHICH DOES NOT WORK
            //"media-col": {
            //    "media-source": "tray-2"
            //},
        },
        // SOLUTION 
        "job-attributes-tag":{
            "media":  ["tray-2"]
        },
        data: data
    };

    printer.execute("Print-Job", file, function (err, res) {
        console.log("Printed: " + res.statusCode);
    });

}));

doc.end();

我试过这个,因为here(4.2.11)media描述为:

  

&#34;媒体&#34;的价值观包括中等名称,中等规模,输入 -      托盘和电子表单,以便一个属性指定媒体。
