How to install Canon LBP3100B printer driver for Mac OS X Lion 10.7.3

The CAPT driver works on 10.7.3, so that is not your issue.

With the printer connected to the Mac via USB cable, it should appear in the Default Add Printer browser. So when you click the plus to add a printer and select Default view, do you see the 3100?

If it is not shown, this is not a fault of the driver but either the USB cable or the printer. Since USB cables have caused all sorts of printing issues over the years then I suggest you start there. If you have another USB printer cable then connect this between the LBP3100 and the Mac and see if the printer is listed. You can also open System Information (Applications > Utilities) and under the Hardware section in the left sidebar, select USB. The top right pane will show all USB busses on the Mac and the printer should be listed under one of these busses if the cable is okay.

A couple of things to note.

After downloading the driver you need to run that CAPT installer. You cannot browse to this CAPT installer from the Add Printer browser. By running the CAPT installer it will copy the Canon files to the correct location on the Mac.

With the CAPT installer completed you then add the printer via the Print Using menu by choosing "Select printer software" - not by choosing "Other". If you then typed CAPT in the search window, this will short list all the models of CAPT printers and your LBP3100 will be one of them.

Hi PAHU,i've recently upgraded my iMac to 10.8. I downloaded the latest Canon driver (version 3.55) from Canon site, and tried to add the Canon LBP3100 for the first time to my iMac. I did what you said, and I can see LBP3100 CAPT in the driver list, and added the printer. However, when I tried to test printing, it stays "sending the file to the printer" in the statusmonitor, and evetually it doesn't print any pages at all.

Do you have any solutions to fix this problem? thanks in advance

The first thing to check is the printer queue that has been created on the 10.8 Mac.

From Finder, navigate to Applications > Utilities and open System Information. In the left column, select Printers. In the right column, select the LBP3100 and copy and paste back here the entry that starts with URI.

thanks for the reply. I followed ur steps to check the printer queue. I could only copy the URI link (which is:

usb://Canon/LBP3100/LBP3108/LBP3150?serial=0000A29AIAWT), however, i couldn't paste to the same place (if im not getting wrong?).

Please see the screenshot as below. Is everything correct there? I still couldn't print anything. 😢

Thanks for showing me the URI. I did mean just copy and paste it back here so I could see what you have set.

So the print queue URI is incorrectly set. The most likely cause is the CAPT Backgrounder process is not running on your Mac. To check, open Activity Monitor and browse through the list. If you don't see the CAPT Backgrounder then open Finder and navigate to HD > Library > Printers > Canon > CUPSCAPT > Backgrounder. Here you will see the CAPT Backgrounder icon. Double-click it. Nothing will appear to happen but if you check Activity Monitor again, the CAPT Backgrounder should be listed. If it is, open Print & Scan, remove the current LBP3100 printer and add it again. Then open System Information again, select Printers and check the LBP3100 print queue URI. It should look something like "cnbma://localhost:59687". If it does, then see if you can print.

OMG!!! This works!!!

I followed every step you listed!! you brilliant!!

it does show this:

URI: cnbma://localhost:59687

I tested printing successfully.

Thanks so much for that!!

Really appreciated!! 🙂

I had a similar problem with the print queue URI being incorrect (printer Canon LBP3100 and OS 10.8). The backgrounder was running. I contacted Canon and they suggested to reset the printing system:

You can do this by going to the apple sign in the top left corner of the screen -> system preferences -> Print and Scan -> Right click under the list of printer (in the white area) or hold CMD and left click and press "Reset printing system". Then, please add your printer and try to print.

I did it and it worked.

I hope this helps others that have the same problem.

Hi,

I have had trouble also loading my LBP3100B with OSX 10.9.1. I have downloaded the driver from the Canon website and ran the app file with it saying it had installed but with no luck when i go to load the printer. I attempted to follow the same instructions however when i go to add the printer in printers and scanners, the drivers do not show up. Any help would be much appriciated.

Try restarting the Mac. This can help to make newly installed printers appear in the Printer Software window.

Champion! That worked. Thanks.

Hi,

I've followed all the steps but still can't get anything to print. I just get connected printer cannot be used.

Please Help!!!😟
