Set Printer

This action specifies the name of the printer to be used for printing the active label.

[Note] Note

This action overrides the printer selected in the label properties.

This action is useful when printing an identical label on multiple printers. Always nest this action under the Open Label action to provide the label with the reference for the preferred printer.

This action reads the default settings (such as speed and darkness) from the selected printer driver and applies them to the label. If you don't use the Set Printer action, the label gets printed using the printer defined in the label template.

[Warning] Warning

Pay attention when switching the printers, e.g. from Zebra to SATO, or even from one printer model to another model of the same brand. Printer settings might not be compatible and the label printouts might not appear identical. Also, label design optimizations for original printer, such as internal counters, and internal fonts, might not be available on the newly selected printer.

About group identifies the selected action.

  • Name: allows you to define a custom action name. This makes actions easily recognizable on the solution's list of actions. By default, the action name is taken from its type.

  • Description: custom information about the action. Enter a description to explain the purpose and role of action in a solution.

  • Action type: read-only information about the selected action type.

Printer group specifies the printer name to be used for the current print job.

  • Printer name: select it from the list of locally installed printer drivers, or manually enter a printer name. Select Data source to dynamically select the printer using a variable. If enabled, select or create a variable that contains the printer name which is used if the action is run.

Action Execution and Error Handling

Each action can be set as a conditional action. Conditional actions only run when the defined conditions allow them to be run. To define these conditions, click Show execution and error handling options.

Execution options are:

  • Enabled: specifies if the action is enabled or disabled. Only enabled actions will execute. This functionality may be used while testing a form.

  • Condition: defines one-line programming expression that must provide a Boolean value (true or false). When the result of the expression is true, the action will execute. Condition offers a way to avoid executing actions every time.

Error handling options are:

  • Ignore failure: specifies whether an error should be ignored or not. With Ignore failure option enabled, the execution of actions continues even if the current action fails.

    [Note] Note

    Nested actions that depend on the current action do not execute in case of a failure. The execution of actions continues with the next action on the same level as the current action. The error is logged but does not break the execution of the action.

Example 41. Example

At the end of printing, you might want to send the status update to an external application using HTTP Request action. If the printing action fails, action processing stops. In order to execute the reporting even after the failed print action, the Print Label action must have the option Ignore failure enabled.


  • Save error to variable: allows you to select or create a variable to save the error to. The same cause of the error is also saved to internal variables ActionLastErrorId and ActionLastErrorDesc.
