[Samba] Re: SAMBA 2.2.3a <-> LPRng 3.8.x

[Patrick Powell]

The 'problem' (Sigh... note the quotes, guys)

is that Samba, bless its little heart,  it trying desperately
to deal with the fact that it has to map 'UNIX' print jobs to
'SMB' print jobs.  The way that it tries to do this is by
putting in a 'magic cookie' in the job name using the lpr '-Jcookie'
option.  After spooling the job it then uses 'lpq' to scan the
queue to get the print job.

There are two solutions to this:

a)  add a new option to lpr to cause it to attach
    an explict magic cookie to the job that can be
    used for removal:

    lpr --cookie=...

    lprm --cookie=...

    and update Samba to use it...

b)  Do not use -J, let Samba have it...

c)  us 'lp', not lpr,  and get the request id:

    h110: {144} % lp /tmp/hi
    request id is papowell at h110+786

    Sigh...
