Print Procedure Errors

Cause. The data line contained a file-system CONTROLBUF operation.

Effect. If this error code is returned by the PRINTREAD procedure, the data line

contains a file-system CONTROLBUF message for the print device. The format of the

CONTROLBUF message is

data-line [0] = operation

data-line [1] = buffer address

data-line [2] = count operation

Recovery. The print procedure should pass the CONTROLBUF message to the

device by way of the file-system CONTROLBUF procedure. The CONTROLBUF

procedure is documented in the Guardian Procedure Calls Reference Manual.

Cause. The print process does not recognize a device name that was received in a

supervisor request.

Effect. The spooler takes the device in question offline. If the error occurs before the

job has finished printing, the job remains in the spooler print queue. If the job has

finished printing but the device has not been closed, the job is deleted from the print

queue.

Recovery. Using Spoolcom, restart the device (for example, issue the DEV

$LP, START command).

If the error persists, stop and then restart the print process.

If the error occurs after you have stopped and restarted the print process, shut down

the spooler and then warmstart it.

Cause. The print process received a request from the supervisor to open a device that

is already open.
