You need to queiry the printer to find out what options it has, like the duplexor or extra trays, before they become available in prefrences.

Using the PCL driver:

If you look in properties and advanced or installed options (one of the tabs should be named something like that) you will find a "get info from printer" button. Hit it.

Using the PS driver:

If you look in properties and advanced or installed options (one of the tabs should be named something like that) you should just be able to make the duplex option available by selecting available next to duplexor in the list.

sorry i cant remember the specific tab names etc. but you should find it with a bit of digging.

I have the exact same issue, our commander wants to print duplex. However, after I try and go to the printer status, the search is unable to come up with or find the printer - even when specified by exact IP?

The printer is online, works fine, I can print to it and even browse to the web interface provided...but can't discover the availability...any ideas?

thanks.

First of all, the optional duplex unit must be installed.... it is NOT standard on this model.

Next:
1. Open Printers and Faxes and right-click the printer object.
2. At the bottom of the list, click Properties
3. A properties window with 8 tabs arranged in ONE row should open (if two rows, you opened the Post-Script driver by mistake; close and open the other driver); click the Options tab.
4. Click the "Get Information from Printer" box. After the operation completes, verify that a "Duplex Module" is listed in the "Items:" list.

Roger that.

We do infact have the duplex hardware piece installed. However, I was tracking all the way, but when you click the "Get Information fro Printer" box, it can't find the printer. I search by broadcast address, specific IP address...every option available, but for whatever reason it can't find the printer. I know the network layers are working fine because the printer prints, and I can PING, etc.

Any other suggestions? Maybe plugging in the printer directly, searching for it then changing the settings?

Thanks again.

IN FACT... we have several Dell 3110cn printers - and on about 1/2 - you can click the get information from printer and it works immediately - the other half...can't seem to find the printer.

Could this be a hardware issue? Or possible a network issue?

Figured it out!

Under the same "Options" tab, if you just highlight the "Duplexer" options, then under the drop down menu below, select, "Available" and it will give you the option when printing...it worked great.

I was just getting ready to reply...... Glad you got it figured.

On the systems that could not find the printer IP...... how were the drivers installled on those systems?

Are these systems on the same subnet as the printer?

1. They were installed just like any printer really, walking through the Add Printer / Fax Wizard through Server 2003, using TCP/IP as your port, then loading the drivers that I got from Dell.com. I had initially put the PS drivers in, but the zip file Dell gives you, has both.

2. We have 7 of the Dell 31XXcn series, they were spread out across 3 different subnets - at least 1 on each subnet worked, so it wasn't layer 2/3. I even took the time to upgrade the firmware on the printer - BUT - when I browsed to the web interface on the exact same model that did work...had the same firmware version? So you got me there, but that fix does work - just telling the print driver what it has installed.

Thanks! Have a good day.

I have the same problem on a 3000cn printer.  Been working fine on networked computers until now.  Now, I can use the Duplex from my original computer on the network, but it is unavailable from additional computers (but before it was available).  When I get to the "Get Information from Printer" button, it (and all other options on the Options tab) is grayed out.  So neither highlighting the Duplex option or clicking "Get Info" will work for me.  Any advice?
