Description

Graphic Printer

The I/O based on this I/O device definition creates graphical information that can then be directed to a graphic printer or to a disk file. This is the default option.

Note: To print to a Graphic Printer, a printer driver must be installed on your computer.

Printer

The device is formatted for printing, as character-based output, and is directed to one of Magic xpa's logical printers. You can redirect a Printer device to a disk file by defining an expression, in the Exp/Var column, which evaluates to a valid file name at runtime.

File

Defines either an input or output disk device, depending on the value of the Access property. The device’s path and name are specified by the expression referred to in the Exp/Var column.

Requester

The Requester I/O device is used by Batch tasks of an project that are invoked by a Call Remote operation or an internet request.

The output made to this I/O device is transmitted back to the calling task or browser upon the completion of the task that opened the device.
