Class CommandRemovePrintJob

      org.simoes.lpd.command.CommandRemovePrintJob

public class CommandRemovePrintJob

extends CommandHandler

This class handles the Remove jobs Command in RFC1179. The RFC description is below:
5.5 05 - Remove jobs

+----+-------+----+-------+----+------+----+
| 05 | Queue | SP | Agent | SP | List | LF |
+----+-------+----+-------+----+------+----+
Command code - 5
Operand 1 - Printer queue name
Operand 2 - User name making request (the agent)
Other operands - User names or job numbers

This command deletes the print jobs from the specified queue which are listed as the other operands. If only the agent is given, the command is to delete the currently active job. Unless the agent is "root", it is not possible to delete a job which is not owned by the user. This is also the case for specifying user names instead of numbers. That is, agent "root" can delete jobs by user name but no other agents can.
Operand 1 = Queue name
Operand 2 = User name
Operand 3 = Print Job Number
NOTE: If user is Administrator or root they can delete any job.
