19.9. Block Job Transfer
Options used:
-
send_block_format FLAG Transfer job as a block
In normal job transfer operations, the sender and receiver have a handshake interaction in order to transfer a print job. Each file is sent individually. The send_block_format option forces a Block Job Transfer operation. This causes the sender to transfer a single file containing all the job printing information, including control file and data files.
The transfer command line has the form:
The receiver will return any acknowledgement of a single 0 octet, and then the size bytes of the job will be transferred by the sender. At the end of the transfer a single 0 octet is added, and the receiver will indicate success by returning a single 0 octet. Any other value returned by the receiver indicates an error condition.
The file transferred by the sender is simply the command lines that it would have normally sent for job transfer, followed by the control or data file values.
