Bax, I appreciate all your help. Now it asks for Device. What now?

Hi,
I had loads of problems getting my 3820 to work as well, I have it connected on the usb port.
/dev/usb/lp0

if your printer connected to the usb port?

No. Connected through parallel port.

Oh,
I'm new to linux, but would the list of modules that my computer is loading be any use to you? Or the driver settings that I picked? I used linuxprinting.org to generate a ppd file (I think its a ppd file). Or anything else?

Where did you put the ppd file?

Hi,
Thats a good question, I used YaST2 which is the SuSE installer. So it was an option, use ppd file. I don't know what it did with it.

I know you tried http://localhost:631, but I thought it had /admin on the end (http://localhost:631/admin), does that make a difference?

One thing I will say is that I endded up reinstaling SuSE because the install was nackard by acpi being enabled while it was being installed. This nackard usb, SCSI and loads of other stuff (probably my printer as well). So I reinstalled with acpi=off as a kernel-parameter and it all works properly now.

just tried it, the only link that worked was:
http://localhost:631/
odd....

http://localhost:631/ works and it brings up the CUPS page. I go through the "Add a Printer" process but it does not work. What did you put when it asks you for a "Device" eg. SerialPort#1,SerialPort#2...

Er... My device was:
/dev/usb/lp0

I gues that if yours is the only printer on the computer and is on the parallel port then is will probably be:
/dev/lp0

Sniff

hmm... Well it gives you a bunch of options like

AppSocket/HP JetDirect
Internet Printing Protocol (http)
Internet Printing Protocol (ipp)
etc.

If I just choose AppSocket/HP JetDirect and type in /dev/lp0 it doesn't work. I've been hearing all this talk about a ppd file. Am I missing something with this?

You should have an option for parallel port 1. I believe I mentioned earlier to check and see if you printer is supported in Linux/CUPS. If CUPs doesn't have the printer listed, do a little Googling. See if ANYBODY has gotten this printer to work in Linux. A .ppd file is somehwat like a Windows driver. Seriously, if you Google a bit, good things will happen. I'm not trying to tell you to RTFM but Googling should solve your problem.

Well I don't have an option for a parallel port 1 so I guess this is a hardware issue. I'll google a little bit for an explanation.

CUPS has the printer driver listed but I don't get the option for parallel port 1.

Okay I've made a significant accomplishment towards getting my printer working. I found a post, while Googling(Thanks bax), that said this problem could be in the BIOS. I rebooted and changed the BIOS settings from Let OS detect Peripherals to Define Parallel Port as LPT1. I reboot and KUDZU comes up and says new hardware found HPDeskJet 3820. WoooHoooo! Everythings cool right? Wrong. It still doesn't work. CUPS know has the option to use Parallel Port #1 so I use that but it still doesn't print anything. I also used the Printing tool and it detected the printer as well but when I go to print a test page it says:

There was an error printing the test page

Arggggg....

Crashed_Again:
you said that you solved your problem with http://localhost:631
you got forbidden access or something and then you fixed it and got into CUPS. What did you do to fix this problem?

I , too cannot configure CUPS because I can't access port 631 on the local host. I think it is a network problem but my network settings seem okay when I check them (ifconfig eth0 and such ) but I am not sure if I would really know if a setting was wrong with my network.
