I had no idea that this could even be done. I'll look into it today.

Over the weekend I was thinking of doing something rougher than that.

The accounting script is called twice by ifhp - once in the beginning 
and once at the end (filestart and fileend). At filestart, for job M, I 
was thinking of dropping a file in (for example) 
"/var/run/printaccounting/printerN" with a username and pagecountM, and 
at fileend, removing that file. If the next printjob in printerN's spool 
"finds" a file in the directory, it can "correct" the quota of username 
by (pagecountM+1 - pagecountM).

That's a bit of a hack though. So I take it there is no neat way to tell 
LPD to disallow removal of active jobs? In most academic environments 
with enterprise printers, the removal of an "active" job does nothing 
because the job has been spooled anyway!

Cheers,
Iordan
