RNAirPrint Configuration

After instalaltion RNAirPrint requires you to configure your locally (USB) or network attached printers. To do that, first call up the CUPS web interface. This can be done either from within Dashboard using the “RNAirPrint” icon on the front page or by clicking on the “Launch” button for RNAirPrint on the “Installed Apps” page. And lastly, you can go to the main web page by entering “https://<ip of your NAS>:631” directly into your browser’s address bar. Once at the main web interface, switch to the “Administration” tab.

There you then click on the “Manage printer” button.

Selection_006

To add a printer, click on the “Add printer” button in the menu that comes up:

Selection_007

This will trigger a request for authentication. To authenticate, use the username “root” together with the password you have set for accessing the web interface of your ReadyNAS:

Selection_008

After successful authentication you will be presented with a list of choice for attaching a printer. There are three sections: Local Printers, Discovered Printers and Other Network Printers. If your printer was automatically discovered it should show up in one of the first two sections. If it isn’t – which is the case most of the times – you first need to tell CUPS where to find your printer. This is done in the third section. Choosing AppSocket/HP JetDirect works well for most modern printer but to be safe you may wish to consult your printer’s manual.

Continuing with this setup, you will be asked for a URL where your printer can be reached by CUPS. You can enter either a host name or an IP address. If unsure the IP address is the better choice in most cases.

Selection_010

After clicking on “Continue” you’re taken to an input form where you can add some description for the current printer and also enable sharing the printer on the network.

Selection_012

When giving a name to the printer make sure that there are no spaces in it. If you want to be able to use that printer from an iOS device, make sure to enable the “Share This Printer” option. After clicking “Continue” yet again you can finally select a manufacturer. Make sure to click on “Continue” and keep the mouse clear from the “Add Printer” button on this screen!

Also try to use a short, meaningful description because that’s the name the printer will show up as on iOS devices.

Selection_013

Next comes the model selection. As you can see, I use a pretty old Samsung printer 😉

Selection_014

Now you can finally click the “Add Printer” button to add your printer to CUPS. However, you’re not finished yet. One final screen allows you to set the default properties like page size and resolution .CUPS should use for that printer.

Selection_015

One last click on “Save Default Options” and you’re done.

Testing With Your iOS Device

To test whether your iOS device can see the printer properly, fire up Safari and open a random webpage. Tap on the “Share” button to the left of the address bar and select “Print” from the menu that pops up.

You will now see an empty list of printers. Tap on “Select printer”.

This should bring up a list of available printers where hopefully the one that you just defined shows up as well. From the screenshot it is also obvious why a short description is better. Oh well.

After tapping on the printer, thereby selecting it, you may also get a panel with some options you can change for the current print process.

Adding your printer to Windows 7

You can also add the printer attached to your ReadyNAS to your Windows 7 PC. Since the steps needed aren’t really obvious, here’s how: (Click on the images to view in original size, Images © by Lianna – thanks!)

For this part, the printer we’re using is an HP Laserjet 1012, connected to the USB port of the ReadyNAS. Please note that Windows will use the name you gave the printer.

The problem there is, that you’ll later on need the URL to the RNAirPrint printer definition so you can tell Windows where to find the printer information. The general name for this URL is http://[ip.of.readynas]:631/printers/[name.of.printer]. If you don’t know the URL, just go to the “Admin” tab of the RNAirPrint config and click on “Manage Printers”:

cupsAdmin

There select the printer you want to add to Windows:

cupsPrinterQueue_withAddressBar

Take note of the URL your browser shows you. Copy it somewhere safe (a Notepad window might be a good idea) and while doing so remove the “s” from the https:// in the URL address so that it’s just http://.

Now on your Windows PC open the “Add Printer” dialogue from the “Devices and Printers” menu. Click on “Add a network, wireless or Bluetooth window”:

Win7AddPrinter1

Since Windows won’t find the printer automatically, we’ll need to give it some help there. To do this, click on “The printer I want isn’t listed”:

Win7AddPrinter2

This will open another input box, where you need to select the “Select a shared printer by name” option and fill in the URL (again: not the https:// one but the one with http:// instead) you copied from the RNAirPrint admin earlier.

Win7AddPrinter3

With a click on “Next” you tell Windows to go and retrieve the printer information. If everything went ok, it will display the usual dialogue for selecting the printer driver.

Win7AddPrinter5

Just select the appropriate driver and finish the installation as you would do for a locally attached printer. The printer attached to your ReadyNAS should now show up on your list of available printers in Windows.
