Method Details

getLogoData

public POSPrinterService.PrintDataPart[] getLogoData()

Data that describe the logo.

Returns:

Array containing POSPrinterService.PrintDataPart objects describing the logo.

getEscLogo

public static POSPrinterService.PrintDataPart getEscLogo(POSPrinterService.PrintDataPart obj,
 int type,
 int subtype,
 int ignored,
 String escdata,
 boolean negated,
 boolean valueispresent,
 POSPrinterService printer)

Checks whether the specified esc sequence parameters form a logo sequence. If so, it returns an EscLogo object. If not, the object given as first parameter will be returned.

Parameters:

obj - An object containing corresponding sequence parameters or null.

type - The sequence type (see EscUnknown, property Esc).

subtype - The subtype (see EscUnknown, property Subtype).

ignored - The value (see EscUnknown, property Value). Will be ignored.

escdata - If value is a data length, the corresponding data. Otherwise null.

negated - The negation flag (see EscUnknown, property Negated).

valueispresent - The present flag (see EscUnknown, property ValuePresent).

printer - This object, used to retrieve logo data.

Returns:

An EscLogo object, if the sequence is a well-formed logo sequence, otherwise obj.

validate

public void validateData(POSPrinterService srv,
 int station)
                  throws jpos.JposException

Description copied from class: POSPrinterService.PrintDataPart

Used to perform additional validation of the print data, if output to the given station occurs. To do this, simply the corresponding method of the POSPrinterInterface used by the given POSPrinterService will be called.

Specified by:

validateData in class POSPrinterService.PrintDataPart

Parameters:

srv - POSPrinterService to be used for validation.

station - Printer station used for validation.

Throws:

jpos.JposException - If not precisely supported with ErrorCode E_ILLEGAL, if not supported and no workaround is possible, with ErrorCode E_FAILURE.
