Duplex printing on Brother broken update 2.8?

It seems like update 2.8,1 fixes things. After applying the update I tried the following things on my HL-5250DN:

1. Set the duplex setting on the printer to "on" and selected None for two-sided printing in the layout section of the print dialog.

This printed duplex (expected behavior).

2. Set the duplex setting on the printer to "off" and selected None for two-sided printing in the layout section of the print dialog.

This did not duplex (expected behavior).

3. Set the duplex setting on the printer to "off" and selected "Long Edge Binding" for two-sided printing in the layout section of the print dialog.

This did duplex (expected behavior).

So the question is, how do I set duplex printing to be the default behavior without just turning it on at the printer (because the driver cannot override that)?

Glad they heard our cries! Just downloaded and installed the 2.8.1 update and it works fine with my HL-5250 DN, and it works fine with duplex, unlike 2.8.

It'd be nice if we could've gotten some confirmation. Geesh!

It looks like I am good to go here too. Duplexing seems to be working fine.

I just installed the new Brother 2.8.1 driver update, printed two pages and duplex works on my HL-5370DW. The new update seems to have also fixed a problem where my printer would not feed paper from the manual tray unless I set paper feed specifically to "manual tray". After the 2.8.1 update, it fed from the manual tray on "Auto Select", as it should.

I own a Brother HL-2140 Laser printer as well as a Canon Pixma MP160 inkjet and a Canon Pixma MP560 inkjet at home. I just recently installed the Brother 2.8.1 driver update and for some reason the "two page printing" option is still disabled, not only for the Brother, but also for both Canon printers.

I even tried installing the printer drivers directly from Brother and Canon but there's still no change. This is unbelievably frustrating.

...for some reason the "two page printing" option is still disabled, not only for the Brother, but also for both Canon printers.

Given that this problem affects the Canon printers as well as the Brother and still happens when you download drivers directly from the printer company websites, I don't see how it could have anything to do with the Brother printer update.

ASilva156, the Brother Printer Update that broke our duplexing didn't "disable" the "two page printing" option on our Brother printers. You could still select it, but it just didn't happen. Further, I don't see how the Brother Update could affect the Canon.

This makes me think that perhaps you need to go to each of your printers preferences and be certain that the duplexing options are shown as added on to your printers. Also, you could try deleting the printers and adding them again ...in fact, that might be the best option. A restart after adding/deleting printers is a good move.

I had the same issue with my Brother HL-5370DW printer not duplex printing but not sure what triggered it. I went to the Brother site and downloaded the driver, installed it and went right to duplex printing. Thanks for the thread.

morsed - The latest Brother Printer Update 2.8.1 from Apple fixes the problem introduced by the original 2.8 Update. It's now safe to use Software Update for this.

I'm having the opposite problem with my Brother MFC-8890DW. It's stuck on duplex and I can't turn it off. Have tried everything mentioned in these pages to no avail.

Is there somewhere we can go in Library to delete all the driver stuff besides the printers folder?

What about the scanner driver? Where can that be found into order to delete it?

Make sure you don't have Duplex forcibly enabled in the hardware, i.e. on the push button interface.

Menu >

4. Printer > Ok

3. Duplex > Ok

Off > Ok

Yeah, that was the problem, don't know how it got set to on. Maybe I did that when it wasn't printing duplex before.

Thanks Derek!

It's great that duplex printing is now working. Has anyone checked if SINGLE sided printing still works? It sure doesn't work for me.

If I turn duplex off (e.g. print single sided) in the print dialog then print, it comes out double sided.

Very frustrating :-(
