Fiscal printer integration sample for Poland

  • Artigo

This article provides an overview of the fiscal integration sample for Poland in Microsoft Dynamics 365 Commerce.

The Dynamics 365 Commerce functionality for Poland includes a sample integration of the point of sale (POS) with a fiscal printer. The sample extends the fiscal integration functionality and supports the POSNET THERMAL HD 2.02 protocol for fiscal printers from Posnet Polska S.A. The sample enables communication with a fiscal printer that is connected via a COM port by using a native software driver. It was implemented and tested by using a software emulator that Posnet provided for the Posnet Thermal HD FV EJ fiscal printer. The sample is provided in the form of source code and is part of the Commerce software development kit (SDK).

Microsoft doesn't release any hardware, software, or documentation from Posnet. For information about how to get the fiscal printer and operate it, contact Posnet Polska S.A.

Scenarios

The following scenarios are covered by the fiscal printer integration sample for Poland:

  • Sales scenarios:

    • Print a fiscal receipt for cash-and-carry sales and returns.

    • Capture a response from the fiscal printer, and store it in the channel database.

    • Taxes:

      • Map to the fiscal printer's tax codes (departments).
      • Transfer mapped tax data to the fiscal printer.

    • Payments:

      • Map to the fiscal printer's methods of payment.
      • Print payments on a fiscal receipt.
      • Print change information.

    • Print line discounts.

    • Gift cards:

      • Exclude an issued/re-charged gift card line from a fiscal receipt for a sale.
      • Print a payment that uses a gift card as a regular method of payment.

    • Print fiscal receipts for customer order operations:

      • A fiscal receipt isn't printed for a customer order deposit.
      • Print a fiscal receipt for carry-out lines of a hybrid customer order.
      • Print a fiscal receipt for the pickup operation for a customer order.
      • Print a fiscal receipt for a return order.

    • Print the customer information that is specified for a sales transaction on a fiscal receipt. An example of this information is the customer's VAT number.

  • End of day statements (fiscal X and fiscal Z reports).

  • Error handling, such as the following options:

    • Retry fiscal registration if a retry is possible, such as if the fiscal printer isn't connected, isn't ready, or isn't responding, the printer is out of paper, or there is a paper jam.
    • Defer fiscal registration.
    • Skip fiscal registration, or mark the transaction as registered, and include info codes to capture the reason for the failure and additional information.
    • Check the availability of the fiscal printer before a new sales transaction is opened or a sales transaction is finalized.

Gift cards

The fiscal printer integration sample implements the following rules that are related to gift cards:

  • Exclude sales lines that are related to the Issue gift card and Add to gift card operations from the fiscal receipt.
  • Don't print a fiscal receipt if it consists only of gift card lines.
  • Deduct the total amount of gift cards that are issued or re-charged in a transaction from payment lines of the fiscal receipt.
  • Save calculated adjustments of payment lines in the channel database with a reference to a corresponding fiscal transaction.
  • Payment by gift card is considered a regular payment.

Customer deposits and customer order deposits

The fiscal printer integration sample implements the following rules that are related to customer deposits and customer order deposits:

  • Don't print a fiscal receipt if a transaction is a customer deposit.
  • Don't print a fiscal receipt if a transaction contains only a customer order deposit or a customer order deposit refund.
  • Print the amount of the previously paid deposit on a fiscal receipt for a customer order pickup operation.
  • Deduct the customer order deposit amount from payment lines when a hybrid customer order is created.
  • Save calculated adjustments of payment lines in the channel database with a reference to a fiscal transaction for a hybrid customer order.

Limitations of the sample

  • The fiscal printer supports only scenarios where sales tax is included in the price. Therefore, the Price include sales tax option must be set to Yes for both stores and customers.
  • Daily reports (fiscal X and fiscal Z) are printed by using the embedded Shift report format.
  • Printing a bar code on fiscal receipts is considered a potential customization, because this feature isn't supported in the embedded formats and can be implemented only by using the customizable Super-format report.
  • The fiscal printer doesn't support mixed transactions. The Prohibit mixing sales and returns in one receipt option should be set to Yes in POS functionality profiles.

Design of extensions

The fiscal printer integration sample for Poland is based on the fiscal integration functionality and is part of the Commerce SDK. The sample is located in the src\FiscalIntegration\Posnet folder of the Dynamics 365 Commerce Solutions repository. The sample consists of a fiscal document provider, which is an extension of CRT, and a fiscal connector, which is an extension of Commerce Hardware Station. For more information about how to use the Commerce SDK, see Download Commerce SDK samples and reference packages from GitHub and NuGet and Set up a build pipeline for the independent-packaging SDK.

Note

The fiscal printer integration sample for Poland is available in the Commerce SDK as of Commerce version 10.0.29. In Commerce version 10.0.28 or earlier, you must use the previous version of the Retail SDK on a developer VM in LCS. For more information, see Deployment guidelines for the fiscal printer integration sample for Poland (legacy).

Commerce runtime extension design

The purpose of the extension that is a fiscal document provider is to generate printer-specific documents and handle responses from the fiscal printer. This extension generates a set of printer-specific commands in JavaScript Object Notation (JSON) format that are defined by POSNET specification 19-3678.

Request handler

The DocumentProviderPosnetProtocol request handler is the entry point for the request to generate documents from the fiscal printer.

The handler is inherited from the INamedRequestHandler interface. The HandlerName method is responsible for returning the name of the handler. The handler name should match the connector document provider name that is specified in Commerce headquarters.

The connector supports the following requests:

  • GetFiscalDocumentDocumentProviderRequest – This request contains information about what document should be generated. It returns a printer-specific document that should be registered in the fiscal printer.
  • GetSupportedRegistrableEventsDocumentProviderRequest – This request returns the list of events to subscribe to. Currently, the following events are supported: sales, printing X report, and printing Z report.

Configuration

The configuration file for the fiscal document provider is located at src\FiscalIntegration\Posnet\CommerceRuntime\DocumentProvider.PosnetSample\Configuration\DocumentProviderPosnetSample.xml in the Dynamics 365 Commerce Solutions repository. The purpose of the file is to enable settings of the fiscal document provider to be configured from Commerce headquarters. The file format is aligned with the requirements for fiscal integration configuration.

Hardware station extension design

The purpose of the extension that is a fiscal connector is to communicate with the fiscal printer. This extension calls the functions of the POSNET driver to submit commands that the CRT extension generates to the fiscal printer. It also handles device errors.

Request handler

The FiscalPrinterHandler request handler is the entry point for handling the request to the fiscal peripheral device.

The handler is inherited from the INamedRequestHandler interface. The HandlerName method is responsible for returning the name of the handler. The handler name should match the fiscal connector name that is specified in Commerce headquarters.

The connector supports the following requests:

  • SubmitDocumentFiscalDeviceRequest – This request sends documents to printers and returns the response from the fiscal printer.
  • IsReadyFiscalDeviceRequest – This request is used for a health check of the device.
  • InitializeFiscalDeviceRequest – This request is used for printer initialization.

Configuration

The configuration file for the fiscal connector is located at src\FiscalIntegration\Posnet\HardwareStation\ThermalDeviceSample\Configuration\ConnectorPosnetThermalFVEJ.xml in the Dynamics 365 Commerce Solutions repository. The purpose of the file is to enable settings of the fiscal connector to be configured from Commerce headquarters. The file format is aligned with the requirements for fiscal integration configuration.
