Cups and Raspberry Pi – How to setup your print server

Print Server is one of those things that makes life easier.  I hooked up my Raspberry Pi and a Docker image in order to have a CUPS server and the Bonjour configuration.

Login to the Raspberry Pi and switch to root (sudo -s or sudo su –)

Check lsusb to see if you can see the USB device.

 root@raspberrypi:~# lsusb 
Bus 001 Device 005: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 004: ID 8564:1000 Transcend Information, Inc. JetFlash
Bus 001 Device 006: ID 0424:7800 Standard Microsystems Corp.
Bus 001 Device 003: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub
Bus 001 Device 002: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
root@raspberryp:~#

If you don’t see it, check to see that the device is properly plugged in.

Check again, and you’ll see your manufacture for your printer listed. (highlighted in red)

 root@raspberrypi:~# lsusb 
Bus 001 Device 007: ID 03f0:7411 Hewlett-Packard
Bus 001 Device 005: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 004: ID 8564:1000 Transcend Information, Inc. JetFlash
Bus 001 Device 006: ID 0424:7800 Standard Microsystems Corp.
Bus 001 Device 003: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub
Bus 001 Device 002: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
root@raspberrypi:~#

Further, I am able to see the exact model that is connected:

 root@raspberrypi:~# lsusb -v | grep -A 20 Hewlett-Packard 
Bus 001 Device 007: ID 03f0:7411 Hewlett-Packard
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            0 (Defined at Interface level)
  bDeviceSubClass         0
  bDeviceProtocol         0
  bMaxPacketSize0        64
  idVendor           0x03f0 Hewlett-Packard
  idProduct          0x7411
  bcdDevice            1.00
  iManufacturer           1 HP
  iProduct                2 Photosmart C4600 series
  iSerial                 3 |||MASKED|||MASKED|||MASKED|||

I’ll use these details downstream in order to install and use the HP driver.

If you still don’t see the USB device, you should check dmesg and look at the pattern for USB.

 [3077006.701281] usb 1-1.2: new high-speed USB device number 7 using dwc_otg
[3077006.831891] usb 1-1.2: New USB device found, idVendor=03f0, idProduct=7411

[3077006.831917] usb 1-1.2: Product: Photosmart C4600 series
[3077006.831925] usb 1-1.2: Manufacturer: HP

If you don’t see it, unplug and plug the device back in.

Copy the Dockerfile and the cupsd file locally (in the folder etc-cups/cupsd.conf). Cupsd is configured to listen on all interfaces: Listen 0.0.0.0:631

Build the Docker image (based off of this image https://github.com/a0js/rpi-cups and uses a different base image https://hub.docker.com/r/arm32v7/debian/ ) docker build -t cups-pi/cups-pi .

Run the Docker image to start the print server

root@raspberrypi:/data/cups-printer# docker run -d -p 631:631 --privileged -v /var/run/dbus:/var/run/dbus -v /dev/bus/usb:/dev/bus/usb -h myhostm.mydomain.org --name cupsm cups-pi/cups-pi:latest
fe6d9bc34c66911f05b011ef185fce95947efb965e90ef2b4ecdd0f1c3a32d68

It’s important to use the -h if you want to remotely access via hostname.

Login to the console http://myserver.mydomain.org:631/admin using print:print

Click Add Printer

Select a local printer “HP Photosmart C4600 series (HP Photosmart C4600 series)”

Click Continue

Click Share This Printer

Click Continue

Click Add Printer

Select Media Type – Letter

Click Set Default Options

Click Add

When you find the Printer, you can add the printer

You now have an image ready for use with a CUPS printer.  (If you rebuild, you may have to re-setup the default printer…. Just warning you ahead of time).  You can always look at http://myhost.mydomain.org:631/printers/HP_Photosmart_C4600_series

If you need to connect to the console, you can look at the docker ps

root@raspberrypi:/data/cups-printer# docker ps
CONTAINER ID        IMAGE                    COMMAND                CREATED             STATUS              PORTS                                    NAMES
fe6d9bc34c66        cups-pi/cups-pi:latest   "/usr/sbin/cupsd -f"   5 minutes ago       Up 5 minutes        0.0.0.0:631->631/tcp                     cups

Extract the CONTAINER ID, and look at the /bin/sh

root@raspberrypi:/data/cups-printer# docker exec
-i -t fe6d9bc34c66 /bin/sh

Then look at the /var/log/cups files, specifically the error_log

  1. I ended up externalizing the cups configuration from the image – docker run -d -p 631:631 –privileged -v /var/run/dbus:/var/run/dbus -v /dev/bus/usb:/dev/bus/usb -v /data/cups-hp/cups:/etc/cups -h <> –name cupsp cups-pi/cups-pi:latest (note the map to /etc/cups, I ended up doing this to simplify restoration.
