Member Function Documentation

IFieldDescription [] LinkOS.Plugin.Abstractions.IFormatUtil.GetVariableFields

(

string

formatString

)

Returns a list of descriptors of the variable fields in this format.

Parameters

formatString

the contents of the recalled format.

Returns

a list of field data descriptors. In CPCL the nth element of the list will contain the integer n and no name. In ZPL, each element will contain an ^FN number and a variable name if present. If the format contains multiple ^FNs with the same number, only the last one will be in the result. See IFieldDescription for an example of how variable fields look.

Implemented in LinkOS.Plugin.ZebraPrinterImplementation.

void LinkOS.Plugin.Abstractions.IFormatUtil.PrintStoredFormat	(	string	formatPathOnPrinter,
		Dictionary< int, string >	vars
	)

Prints a stored format on the printer, filling in the fields specified by the Map. The values of any format variables will be encoded using the default encoding type. See System.Text.Encoding for more information about encoding types.

Parameters

formatPathOnPrinter	the location of the file on the printer (e.g. "E:FORMAT.ZPL").
vars	a dictionary which contains the key/value pairs for the stored format. For ZPL formats, the key number should correspond directly to the number of the field in the format. For CPCL formats, the values will be passed in ascending numerical order.

Implemented in LinkOS.Plugin.ZebraPrinterImplementation.

void LinkOS.Plugin.Abstractions.IFormatUtil.PrintStoredFormat	(	string	formatPathOnPrinter,
		string[]	vars
	)

Prints a stored format on the printer, filling in the fields specified by the array. The values of any format variables will be encoded using the default encoding type. See System.Text.Encoding for more information about encoding types.

Parameters

formatPathOnPrinter	the name of the format on the printer, including the extension (e.g. "E:FORMAT.ZPL").
vars	an array of strings representing the data to fill into the format. For ZPL formats, index 0 of the array corresponds to field number 2 (^FN2). For CPCL, the variables are passed in the order that they are found in the format.

Implemented in LinkOS.Plugin.ZebraPrinterImplementation.

byte [] LinkOS.Plugin.Abstractions.IFormatUtil.RetrieveFormatFromPrinter

(

string

formatPathOnPrinter

)

Retrieves a format from the printer. On a ZPL printer, only .ZPL files are supported. On a CPCL printer, only .FMT and .LBL files are supported. This function will only pull CPCL files on ZebraLink Mobile printers (RW, MZ, QL+).

Parameters

formatPathOnPrinter

the location of the file on the printer (e.g. "E:FORMAT.ZPL").

Returns

the contents of the format file.

Implemented in LinkOS.Plugin.ZebraPrinterImplementation.
