Hi all (hope your there too, Till)

After an LM 7.2 install/print struggle, I'd like to pass on a few printer
related 'gotcha's' that I believe are problematic. I'll try and be as
terse as I can (I have trouble being terse). Comments are most welcome.

#1: /dev/lp0 vs /dev/lp1

When I upgraded from redhat 5.2 to 6.2 there was a big deal about how
*now* the first parallel port is lp0, in lieu of lp1. I seem to remember
the reason being kernel related, but it may have been my own redhat ==
linux subconscious. During my install of LM 7.2 I automatically chose lp0
as the parallel printer port and the install did *not* see the printer.
Moreover, the CUPS documentation suggests that, in general, parallel
printers are on lp1. Also, the "add printer" wizard from the kups tool
still tells me I don't have a printer (it's on lp0 and working great now),
and the wizard's parallel port list only shows "parallel port #1". I
suspect both the LM 7.2 install routine and the kups wizard are broken in
this respect, and if this is the case, then the many people fleeing from
the redhat 7.0 mess to Mandrake might have some serious headaches.

#2:  CUPS http://localhost:631/adm

Although this tool does see lp0, I suspect it will work if and only if you
have a good /etc/cups/cupsd.conf file. At the moment, this
http://localhost:631/adm does *not* work here, although I managed to get
it to work very briefly during a blitz 'trial & error" session. I think it
has to do with the "broadcasting" entries in the cupsd.conf file (see
below). Nonetheless, this tool, which can configure your cupsd.conf file,
will be useless unless you have a working cupsd.conf file to begin with.
If I'm mistaken here, please let me know, because my default cupsd.conf
file from the LM 7.0 install had all the important entries remmed out.

#3:  The /etc/cups/cupsd.conf file / 

I think this file could use a few more comments, or be fully docummented
elsewhere. CUPS is new, and a 'man cupsd.conf' assumes a degree of
knowledge (as it should) that was not needed with the admittedly
'brain-dead'  LPD. After 4 years of battling with redhat, I like to think
that I'm no longer a total Linux newbie. But, like many Linux users, I
don't administer a multi-machine network, and the occasional comment
relating to a single loopback system would be very helpfull. "Should
broadcasting be on? Should I be broadcasting to 127.0.0.1? The comments
certainly do not have to be comprehensive; a *single* sentence aimed at the
home user who is not on a LAN, nor a LAN administrator, would be
appropriate, I think, since a whole lot of mandrake/CUPS users are one
home machine. Of course, that is what the wizards are for. But if the
wizard is broken, or if it assumes underlying knowledge of the system,
then that wizard is worse than useless. I think the kups "add printer"
wizard is both broken and dangerous: you need to be lucky for it to work.

Dave.
(and aren't you glad I wasn't verbose?)
