DOVER <filename> causes the file to be printed on the Dover printer.
BOISE <filename> causes the file to be printed on the Boise printer.
IMPRINT <filename> causes the file to be printed on the IMPRINT printer.
ESPOOL <filename> causes the file to be printed on the ESP/Imagen printer.
XSPOOL <filename> causes the file to be printed on the XGP.

UNSPOOL allows you to selectively delete spooler requests.
QSPOOL displays the spooler queues: Q/D shows only Dover queue, Q/B Boise, etc.

You must be logged in to give any of these commands except QSPOOL.

Some spooler switches, which can follow the name of the file being spooled:

/NOTITLE	Suppress the header page
/NOHEADING	Suppress the header line on each page
/DELETE		Delete the file after listing
/DUMP		Spool in octal words

Page ranges can follow a filename (must precede any switches):
(n1,n2:n3,n4)	means page n1, pages n2 to n3 inclusive, and page n4

Time delay command - don't print the listing until specified time:
/HOLD = hhmm	where hhmm is 4 digits of 24 hour time (in the future).

For complete details on the use of SPOOL, see the printed Monitor Command Manual
or its online version in MONCOM.BH[S,DOC], with updates in MONCOM.UPD[S,DOC].
