打印机无法从DeviceHub接收作业

时间：2019-06-10 14:11:50

标签： c# acumatica

我对这个问题有确切的描述：Device Hub communication with printer queue

由于该问题既没有接受也没有可接受的答案，所以我再次提出问题。

我已经用Acumatica配置了DeviceHub，并且显示了我的打印机。我正在通过PXAction发送打印作业。执行该操作后，DeviceHub会记录作业的成功接收，但是打印机队列从未收到该作业。

这是我的代码，因为这是StackOverflow：

public PXAction<PX.Objects.CR.BAccount> PrintAddressLabel;

[PXButton(CommitChanges=true)]
[PXUIField(DisplayName = "Print Label")]
protected void printAddressLabel()
{
  BAccount baccount = Base.Caches[typeof(BAccount)].Current as BAccount;
  string bAccountID = baccount.BAccountID.ToString();

  Dictionary<string, string> parameters = new Dictionary<string, string>();
  parameters["BAccountID"] = bAccountID;

  PXReportRequiredException ex = null;
  ex = PXReportRequiredException.CombineReport(ex, "ZRCRADDR", parameters);
  SMPrintJobMaint.CreatePrintJobGroup("DYMOLABEL", ex, "Address Label");
}

有人可以指出我的帮助方向吗？

编辑：

进一步测试后，我发现了以下内容：

Acumatica将使用内置的打印过程成功打印到我的DeviceHub打印机。但是，当打印这些作业之一时，DeviceHub日志显示一个POLL事件。尝试从我的代码打印时，DeviceHub会记录一个NT事件，该事件永远不会进入打印机队列。

在进一步测试中，2019 R1中的日志略有变化。从Acumatica打印发票也会导致NT事件。但是，与在Acumatica中创建的作业和在代码中创建的作业相比，只有一行不同。

绿色= Acumatica的工作

橙色=代码中的工作

代码发送的作业中缺少行Printer DYMOLABEL - printing PDF to \\*printer*。

如果我的理解正确，那么您需要通过Automation Steps屏幕添加报告，并将其与DeviceHub关联。
为发票编写了示例，当该过程将在需要打印发票的情况下进行，然后将使用以下设置：

public class CustomEntry : PXGraph<CustomEntry>
{
 [PXQuickProcess.Step.IsBoundToAttribute(typeof(UsrPath.SO303000.Balanced.Report.PrintLabelReport), false)][PXQuickProcess.Step.RequiresStepsAttribute(typeof(SOQuickProcessParameters.prepareInvoice))]

                        return "Print Label";
                    }
                }
                public string OnSuccessMessage
                {
                    get
                    {
                        return "<Invoice form> is prepared";
                    }
                }
                public string OnFailureMessage
                {
                    get
                    {
                        return "Preparing Invoice form";
                    }
                }
            }

Configuration of the Device Hub

答案 1 :(得分：0)

我不愿意将此作为答案发布，因为代码与Vardan所发布的代码非常相似。但是该代码对我不起作用，而此代码对我有用。它实际上来自他引用的同一链接，但最终来自链接的源代码，由于我对他的帖子发表了评论，因此添加了该链接。我已经稍微修改了代码，因为我不需要它来做他所做的一切。

希望它可以帮助其他人。

自定义类：

[System.SerializableAttribute]
public partial class PrintParameters : IBqlTable, PX.SM.IPrintable
{
  #region PrintWithDeviceHub
  public abstract class printWithDeviceHub : IBqlField { }

  [PXDBBool]
  [PXDefault(typeof(FeatureInstalled<FeaturesSet.deviceHub>))]
  [PXUIField(DisplayName = "Print with DeviceHub")]
  public virtual bool? PrintWithDeviceHub { get; set; }
  #endregion

  #region DefinePrinterManually
  public abstract class definePrinterManually : IBqlField { }

  [PXDBBool]
  [PXDefault(true)]
  [PXUIField(DisplayName = "Define Printer Manually")]
  public virtual bool? DefinePrinterManually { get; set; }
  #endregion

  #region Printer
  public abstract class printerName : PX.Data.IBqlField { }

  [PX.SM.PXPrinterSelector]
  public virtual string PrinterName { get; set; }
  #endregion
}

public class CsPrintMaint : PXGraph<CsPrintMaint>
{
  public void PrintReportInDeviceHub(string reportID, Dictionary<string, string> parametersDictionary, string printerName, int? branchID)
  {
    Dictionary<string, PXReportRequiredException> reportsToPrint = new Dictionary<string, PXReportRequiredException>();
    PrintParameters filter = new PrintParameters();
    filter.PrintWithDeviceHub = true;
    filter.DefinePrinterManually = true;
    filter.PrinterName = printerName;

    reportsToPrint = PX.SM.SMPrintJobMaint.AssignPrintJobToPrinter(reportsToPrint, parametersDictionary, filter, 
           new NotificationUtility(this).SearchPrinter, CRNotificationSource.BAccount, reportID, reportID, branchID);

    if (reportsToPrint != null)
    {
      PX.SM.SMPrintJobMaint.CreatePrintJobGroups(reportsToPrint);
    }
  }
}

BusinessAccountMaint扩展程序： 

public class BusinessAccountMaint_Extension : PXGraphExtension<BusinessAccountMaint>
{
  public PXAction<BAccount> printAddressLabelNH;
  [PXButton(CommitChanges = true)]
  [PXUIField(DisplayName = "Print Label (NH)")]
  public virtual IEnumerable PrintAddressLabelNH(PXAdapter adapter)
  {
    int? branchID = this.Base.Accessinfo.BranchID;
    Dictionary<string, string> parametersDictionary = new Dictionary<string, string>();
    BAccount bAccount = this.Base.Caches[typeof(BAccount)].Current as BAccount;
    parametersDictionary["BAccount.BAccountID"] = bAccount.BAccountID.ToString();

    CsPrintMaint printMaintGraph = PXGraph.CreateInstance<CsPrintMaint>();

    printMaintGraph.PrintReportInDeviceHub("ZRADDRBA", parametersDictionary, "DYMOLBLNH", branchID);

    return adapter.Get();
  }
}
