The PosPrinterBase class verifies that the application has the device opened, claimed, and enabled. PosPrinterBase validates the parameters and device state, and may throw PosControlException exceptions with the following values:

Value

Meaning

Illegal

a) The requested printer station must be PrinterStation.Receipt, PrinterStation.Journal, PrinterStation.Slip; or b) the requested printer station doesn’t exist (that is, the value of the CapRecPresent, CapJrnPresent, or CapSlpPresent property is false).

If no exception is thrown, the PosPrinterBase class calls ValidatePrintImpl.
