lprm vs. apsfilter

[Steffen Hein <s.hein@xxxxxxxxxx>]

Hallo friends,

running apsfilter since FreeBSD 2.2.8, I noticed  an
unpleasant behavior after the lprm command since
upgrades 4.0-4.3  ( in the default  installation. You
- better than me - identify the pertinent apsfilter
versions.)

Formerly, the lprm statement  recursively removed all
printing orders from the spooler and stopped the printer.
Since then, the last order seems to be removed , but my
printer (HP-Deskjet 850C) continues spitting out 'garbadges'.
There seems to be no conventional means to stop lp.
Page after page, two lines of  hieroglyphs, then the next page...
Further 'lprm' commands, even repeated from root (or off-
switching the printer,  clearing its memory, etc. ) have
no effect. - The spook only disappears after reboot.

A genuine UNIX command, such as lprm, should  remain
effective under any application - shouldn't it ?
