Yes - I realized that my choice of words wasn't the best.

Then please rephrase or re-explain. We are not mindreaders.

I am aware of the driver requirement, but what I was trying to say is that I didn't have one USB printer that I wanted to work, I wanted to get the general idea of how to get any printer to work.

Then that is the question you should have asked.

Without further information, the answer is, again, to install cups (see / re-read the posts above) and use it.

If you have more thoughts on how Ubuntu handles a newly plugged USB printer, what it does and if the driver is not found, how it handles it?

You have to install your printer, the easy way is with cups - that is what cups is there for.

If it turns out that cups doesn't know about your printer, then we have a different problem, but please just start at the beginning.

I think you are (perhaps unintentionally) trying to make things more complicated than they really are.

Nothing succeeds like success. So far as I can tell, you have not been able to follow the hints given to get even a *SINGLE* printer to work. Once you understand the process of getting that first printer to work you can begin to generalize with all the long list of USB printers you have in mind.

It is very likely...the CUPS system covers a comprehensive list of printers and printer types from the get-go.

Did you install and start 'cupsys'? If so, have you then followed the simple steps to connect your system to the printer you have plugged in? If not, then do this:

Code:

apt-sys install cupsys

Work with us here....did you do as tredegar indicated?

tred@vaio:~$

If so, please post the results. The question is, 'do you have the right packages installed and the cupsd daemon running?'

Cups wants you to tell it how to handle a newly connected printer. It is not "Plug and Pray" in the true sense. It is, however, very simple to connect a new printer once you know how; a matter of a few minutes or seconds of effort.

Ok, I installed cups and now I have this:

Code:

root@ubuntu:~# ps -Al | grep cups
5 S     0  1536     1  0  80   0 -  1605 epoll_ ?        00:00:00 cupsd

I was also able to see the http://localhost:631

I did add a printer and everything is working fine with a printer.

You're on the right track!

Going back to your first post, you want to find a way to add printers (I assume that it isn't an infinite list of hardware, just what you have on-hand) and print to the queue which services the 'printer-de-jour' without a lot of hassel.

Are we on the right track?

That's correct. I just have a couple of printers on hand.

Yes, we are on the right track!!!

Thanks!
