Using Synology DS211j as an AirPrint Print Server for Brother HL-2170W

I have a Brother HL-2170W printer that I’m using as a wireless printer. One thing I wanted to do was use AirPrint from my iPhone to print if the need should arise, as it does from time to time. My Synology DS211j includes a USB print server with Bonjour and AirPrint support, so I knew I could plug my printer into it via USB and use it as a print server, but there was the issue of the already-configured wireless clients.

I wondered: Since I’m already using my printer wirelessly, can I just plug the printer into the NAS using the USB port and use both USB and wireless? The answer to that is actually yes, according to this post at UbuntuForums. You can use USB and either wired or wireless at the same time, but you cannot use both wired at wireless at the same time.

Now that I had that important issue aside, it was time for setting it up.

First, physically plug the USB cable from the printer to the NAS. You should be able to verify that the printer shows up in Control Panel > External Devices as shown here:

Once that’s done, click the printer to select it, then click USB Printer Manager > Set Up Printer:

Since the DS211j didn’t have a specific print driver listed for this model, I took the known-working driver configuration from my “Ubuntu and Brother HL-2170W” post, and set it up as shown below:

  • Mode: Network Printer
  • Advanced Settings: Enable AirPrint
  • Printer Brand: Generic
  • Printer Model: Generic PCL 5e Printer

After that, I hit Save and then Close, and I was able to print a test page successfully by clicking on the printer and then clicking USB Printer Manager > Print Test Page. One thing to be aware of is that the DS211j is a bit lacking in RAM, so print jobs can take a bit (up to 5 minutes) from the time they’re sent to the server until they come out of the printer.
