Thank you so much for responding. It is terribly lonely when you are new to
linux and it is not cooperating. I hate having to go back to NT4 to get
serious work done just because I cannot print in cups.
I did solve the hostname problem and changed it back to the default
(localhost.localdomain). But that is not the whole problem with my cups.
Although that change now lets me access http://localhost:631 cups will still
not let me add a printer.
HOWEVER, I now have another lead but do not know how to follow it correctly:
I may have mentioned that in all my attempts to get cups to work, on 2
fleeting occasions, kups did show that a local printer was correctly
installed at lp0 !!!! I had indeed installed a printer when I installed
Mandrake 7.2 but it just would not show up as present when I start up kups
and I could not add a printer in kups because it would tell me that it could
not find any parallel ports. At first I did not know what caused the
installed printer to correctly show up during those 2 fleeting occasions.
But, by dint of trying and trying (and numerous hours wasted), I suddently
could reproduce it!
****If I am connected to the internet via dialup modem on my standalone not
networked pc, the printer shows up as installed! However, as soon as I go
off line, the installed printer dissappears.
So, - my cups system only seems to find the printer if I am connected to the
internet but not otherwise. Does this give anyone a hint where it can help
me get cups to work?
Incidentally the way to change hostname is via harddrake/linux
config/network, but to get the change to be really effective I need to
reboot (or restart something if I knew how). The default name originally
installed by Mandrake installation was localhost.localdomain.
Someone please help me. I cannot believe I am the only one having this
problem with cups.
Thanks.
