The lpc move command is used to move jobs in one queue to another queue on an individual basis, while the lpc redirect command redirects all incoming jobs to a new queue. Edit the printcap file so it has contents indicated below, use checkpc -f to check the printcap, and then use lpc reread to restart the lpd server.

We first stop the queues so that the jobs will remain in them. We then use the lpc move fromqueue id toqueue command to select a job in the fromqueue and move it to the toqueue. A list of job numbers, job IDs, or glob patterns to match job IDs can be used to select the job.
The lpc redirect fromqueue toqueue will cause all incoming jobs to be redirected to the specified queue. You can execute the following commands and observe the results.
h4: {243} % lpc redirect lp lp2 Printer: lp@h4 forwarding to 'lp2' lp@h4.private: redirected h4: {244} % lpq -a Printer: lp@h4 (printing disabled) (redirect lp2) Queue: no printable jobs in queue Printer: lp2@h4 (printing disabled) Queue: no printable jobs in queue h4: {245} % lpr /tmp/hi h4: {246} % lpq -a Printer: lp@h4 (printing disabled) (redirect lp2) Queue: no printable jobs in queue Status: job 'papowell@h4+935' removed at 09:08:21.410 Printer: lp2@h4 (printing disabled) Queue: 1 printable job Server: no server active Rank Owner/ID Class Job Files Size Time 1 papowell@h4+935 A 935 /tmp/hi 3 09:08:21
To turn redirection off, use lpc redirect queue off as shown in the example below:
h4: {247} % lpc redirect lp off Printer: lp@h4 forwarding off h4: {248} % lpq Printer: lp@h4 (printing disabled) Queue: no printable jobs in queue Status: job 'papowell@h4+935' removed at 09:08:21.410
