I had read that page (perhaps I should have said that I had ;-), but:
- before() and after() functions are not mentioned (I can guess that 
they are "normal" functions defined only in net.*);
- the arguments to after and before seem service names (f.i., "but 
want your service to be started before (or after) another service"), 
but... what kind of service is "net"? Is it net.lo, net.eth?, 
netmount? There is no "net" service... 

I'm using a notebook (HP dv5078) and an all-in-one printer (HP PSC 
1510). The hplip service has not worked until I removed it from the 
default runlevel and executed it in local.start.
I've found that hplip worked if started after iptables, didn't work if 
started before iptables.
I've contacted HP, and their answer was:

My default init sequence [was] is different:
- domainname
- net.lo
- syslog-ng
- anacron
- net.eth0
[- hplip, when it didn't work]
- cupsd
- gpm
- iptables
- netmount
- local -> hplip

I'ld like to try the sequence suggested by HP, but I can't understand 
what could I do. For example, how could I execute iptables (which is 
executed "before net", but after net.*) before net.lo?

Yes, I could try:
- replacing "before net" with "before net.lo" in iptables;
- adding "after iptables" to cupsd;
and so on, but even if some editing worked, eventually after a few  
booting failures, that would be a "blind workaround" ;-)
