前言

很久沒有寫博客了(大概有4個月的樣子了吧)，從2015年8月份開始一直忙于公司的系統，直到2016年6月底全部上線；包含4個廠區，每個廠區都是上千人的規模，而負責搞這個項目的算上我只有2個人，說多了都是淚：

美工？沒有

測試人員？沒有

DBA？沒有

架構師？沒有

運維？繼續沒有

估計大家都沒遇見過這樣的工作吧？哈哈.

歷經艱難、跟各個部門(IE、PE、生產、PMC、QA等)唇槍舌戰、好在在6月底總算是全部上線，總算是一點欣慰，畢竟決定了接手這個項目，那就要用心去做，只有用心了才能做好。

吐槽完畢，下面開始說正事兒

********我是華麗的分割線************************************************

公司的系統上線之后，我也稍微可以緩口氣了，加班稍微少了一點，一般到了下午6點半就能下班，所以我還是決定將2015年初整理的這套項目拿出來繼續優化，該項目已Web模式為主、客戶端模式為輔，互相結合使用；目前主要包含以下幾個主要功能模塊：

本文主要說一下打印的問題，在生產制造業中條碼打印是非常頻繁的，也是必不可少的；我曾經親身經歷過這么一件事情：生產線在進行包裝的時候，打印了兩張卡通標簽，但是操作員在將卡通標簽貼在盒子上的時候貼反了，也就是說標簽上面的序列號與盒子里面裝的實物完全對不上，為此在海關被攔截了，當時廠里派了QA、生產、貨倉與IT一同去海關處解決這個問題，我剛好在其中，整個過程是非常繁瑣的，為此公司高層也要求必須杜絕這種品質事件，故我們也是采用了"在線打印"的方式進行包裝，并且只有QA才有標簽重打的權限。

這個故事反應了生產線的真實現象，所以我這邊采用如下方式完成打印：

function PrintLabel(box) {
 var api = '<%=MTS.Utility.MtsTool.GetApi() %>';
 var lurl = api + "?type=3&action=get_carton_sn&carton_sn=" + box;
 $.ajax({ url: lurl,
 cache: false,
 dataType: "text",
 success: function (data) {
 if (data == null || data == undefined) {
 alert("");
 return;
 }
 var arr = data.split("|");
 if (arr[0] == "0") {
 alert(arr[2]);
 return;
 }
 var t = eval("(" + arr[2] + ")"); // 
 try {
 var labelId = $("#hid_LabelId").val();
 window.external.PrintLabel("", t.key, t.value, ",", labelId);
 } catch (e) {
 };
 }
 });
 }

以上代碼是Web應用程序中的腳本，主要是通過API獲取需要打印的數據，這里返回的是text類型，其實也可以返回Json格式的數據；用戶完成包裝之后系統會按照包裝規則產生一個唯一的卡通箱號，那么這個箱號就作為API的參數 carton_sn= box傳進去，根據該箱號返回真實的包裝數據；然后通過window.external調用客戶端的打印函數。

通過如下代碼獲取本地默認打印機：

//獲取默認打印機
 System.Drawing.Printing.PrintDocument pringdocument = new System.Drawing.Printing.PrintDocument();
 string pring_name = pringdocument.PrinterSettings.PrinterName;//打印機名

因為我這里的客戶端程序就是對Web程式加殼了，通過這個客戶端程序就可以方便的獲取本地默認打印機，采用這種方式比在網頁中安裝 activex 控件要爽的多，誰用誰知道.

網頁傳過來的參數以鍵值對為標準：

 string[] keys = key.Split(splitKey.ToCharArray(), StringSplitOptions.None);
 string[] values = value.Split(splitKey.ToCharArray(), StringSplitOptions.None);

我這里調用BarTender進行打印，代碼如下：

 format = (BarTender.FormatClass)engine.Formats.Open(filename);
 format.SetNamedSubStringValue(key, value);
 format.PrintSetup.Printer = printerName;
 BarTender.Messages msg = null;
 format.Print("0", false, 1, out msg);

以下代碼是Code 128格式的條碼：

public class Code128
 {
 private DataTable m_Code128 = new DataTable();
 private uint m_Height = 40;
 /// <summary>
 /// 高度
 /// </summary>
 public uint Height { get { return m_Height; } set { m_Height = value; } }
 private Font m_ValueFont = null;
 /// <summary>
 /// 是否顯示可見號碼 如果為NULL不顯示號碼

 public Font ValueFont { get { return m_ValueFont; } set { m_ValueFont = value; } }
 private byte m_Magnify = 0;
 /// <summary>

 public byte Magnify { get { return m_Magnify; } set { m_Magnify = value; } }

這樣一來，操作員手上沒有多的條碼，必須包裝完成之后系統才會一對一的打印一份條碼出來，完成一個產品的包裝就貼一個條碼，很大程度上面避免了條碼混亂的問題.
