打印机无法从 DeviceHub 接收作业

Question

我有这个问题中描述的确切情况：Device Hub communication with printer queue

由于这个问题既没有被接受的答案，也没有可接受的答案，我再次问这个问题。

我已经用 Acumatica 配置了 DeviceHub，并显示了我的打印机。我通过 PXAction 发送打印作业。执行操作后，DeviceHub 记录作业的成功接收，但打印机队列从未接收到它。

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");
}

有人能给我指出一个有用的方向吗？

编辑：

经过进一步测试，我发现了以下内容：

Acumatica 将使用内置的打印流程成功打印到我的 DeviceHub 打印机。但是，在打印其中一项作业时，DeviceHub 日志会显示 POLL 事件。当尝试从我的代码打印时，DeviceHub 记录了一个 NT 事件，该事件永远不会进入打印机队列。

经过进一步测试，在 2019 R1 中，日志略有变化。从 Acumatica 打印发票也会导致 NT 事件。但是，与在 Acumatica 中创建的作业与在代码中创建的作业有一条不同的地方。

绿色 = Acumatica 的工作

橙色 = 代码中的作业

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

如果我理解正确，那么您需要通过Automation Steps 屏幕添加报告并将其与DeviceHub 关联。
示例是为 Invoices 编写的，当流程将在需要打印 Invoice 的情况下工作时，将使用这些设置：

public class CustomEntry : PXGraph<CustomEntry>
{
 [PXQuickProcess.Step.IsBoundToAttribute(typeof(UsrPath.SO303000.Balanced.Report.PrintLabelReport), false)][PXQuickProcess.Step.RequiresStepsAttribute(typeof(SOQuickProcessParameters.prepareInvoice))]
 [PXQuickProcess.Step.IsInsertedJustAfterAttribute(typeof(SOQuickProcessParameters.prepareInvoice))]
 [PXQuickProcess.Step.IsApplicableAttribute(typeof(Where<Current<SOOrderType.behavior>, In3<SOOrderTypeConstants.salesOrder, SOOrderTypeConstants.invoiceOrder, SOOrderTypeConstants.creditMemo>, And<Current<SOOrderType.aRDocType>, NotEqual<ARDocType.noUpdate>>>))]
 protected virtual void SOQuickProcessParameters_PrintInvoice_CacheAttached(PXCache sender)
 {
 }
}
public static class UsrPath
{
 public static class SO303000
 {
    public static readonly Type GroupGraph = typeof(SOInvoiceEntry);
    public static class Balanced
    {
        public const string GroupStepID = "Balanced";
        public static class Report
        {
            public const string GroupActionID = "Report";
            public class PrintLabelReport : PXQuickProcess.Step.IDefinition
            {
                public Type Graph
                {
                    get
                    {
                        return UsrPath.SO303000.GroupGraph;
                    }
                }
                public string StepID
                {
                    get
                    {
                        return "Balanced";
                    }
                }
                public string ActionID
                {
                    get
                    {
                        return "Report";
                    }
                }
                public string MenuID
                {
                    get
                    {
                        return "Print Label";
                    }
                }
                public string OnSuccessMessage
                {
                    get
                    {
                        return "<Invoice form> is prepared";
                    }
                }
                public string OnFailureMessage
                {
                    get
                    {
                        return "Preparing Invoice form";
                    }
                }
            }
        }
     }
  }
}

        Dictionary<string, PXReportRequiredException> dictionary2 = new Dictionary<string, PXReportRequiredException>();

Configuration of the Device Hub

Answer 2

我不愿将此作为答案发布，因为代码与 Vardan 发布的代码非常相似。但是该代码对我不起作用，而该代码可以。它实际上来自他引用的同一个链接，但它来自最后链接的源代码，这是由于我对他的帖子的评论而添加的。我稍微修改了代码，因为我不需要它来完成他所做的一切。

希望它可以帮助别人。

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：

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();
  }
}
