Thanks for your replies about this.  I am sorry I have not responded 
before.  I got caught up in a CUPS upgrade which led to usblp and other 
problems about which I have written elsewhere.  On the other hand the 
above problem seems to have disappeared.  It seems now that LibreOffice 
only sends documents once for multiple copies whereas before it sent a 
long document including repeated copies.  I am using the generic 
postscript driver.
