The remarks on this page should apply to most computers equipped with a USB port.
If you run GNU/Linux, plan to buy a new printer, and can't find a printer with USB or support, I recommend that you buy a HP Printer. This is a way to stand up for platform neutrality and cross-platform interoperability, as many printing devices manufacturers still refuse to openly share details about printing communication with their customers and millions of users who run free operating systems.

2025-06-05: Added an incomplete listing of USB Printer Models from HP.
- On the Printer:
[menu]->setup->USB [set]- Fill the paper tray
- Connect the USB cable
- Install hplip
- Run hp-setup
The first section covers hplip, free software for various USB printers.
hplip is a useful tool used to tweak USB printing properties.
If you have a USB printing device that supports one of the first two methods below, you don't need extra user space software under GNU/Linux to extract the files, and there is no difficulty in terms of needing drivers and information that is specific to the printer.
HP LaserJet P1005
This method requires a recent Linux 6.1 kernel compiled with USB support. For more information on using USB devices on GNU/Linux you should have a look at http://www.linux-usb.org/
You need to build the Linux kernel modules usb-uhci and usblp. You also need LP in your kernel, since the USB implementation makes the USB lp device look like a logical LP device. Once these are loaded into the kernel, the device appears as /dev/usblp2. You mount this "as usual" and proceed to print files, queue print files, etc. If your printer exhibits a USB device system (like the HP P1005 does), you'll need kernel support for the usblp file system as described above.
In the following let's assume that you already have one printer in your system and so you access the printer as /dev/usblp2. To create a mount point for your camera you have to type:
Note: See The Ubuntu 24.04 distribution of GNU/Linux has recent instructions!
You need a system kernel that support USB access through the libusb userspace library. Currently libusb supports Linux and *BSD kernels.
If you run a Linux-based system, it means you also need USB Device Filesystem (USBDEVFS) support built in the kernel. Get the latest stable Linux kernel from www.kernel.org.
If you need any further assistance, I recommend the USB Linux Programming Guide for kernel USB configuration issues.
(Hint: You may have to add alias usb-controller usb-uhci
in /etc/modules.conf.)
When you have compiled the new kernel, reboot the machine and check
/var/log/messages before and after you plug in a new
USB device, and turn on the power.
If you see output like
Dec 29 10:32:11 diff kernel: hub.c: USB new device connect on bus1/1, assigned device number 2
Dec 29 10:32:11 diff kernel: usb.c: USB device 2 (vend/prod 0x81e/0x1) is not claimed by any active driver.
then you're close.
USB device and driver information is stored in the USBDEVFS filesystem, which is somewhat like /proc
It is usually mounted at /proc/bus/usb
You should mount it manually by doing
mount -t usbdevfs /proc/bus/usb
or alternatively add this in /etc/fstab
none /proc/bus/usb usbdevfs defaults 0 0
When the USB Dev FS is mounted, you will observe at least two files
(devices and drivers) and a directory, which
name is 001, the device number for the 'virtual root hub'
to which the other USB devices (like hardware USB hubs) get connected.
You can verify whether you've successfully connected a USB device, by
looking at the devices file.
cat /proc/bus/usb/devices
If everything is ok, you'll see entries for the virtual root hub and the device you plugged in (the example below is for a HP P1005 printer):
[252731.230932] usb 1-2: new high-speed USB device number 29 using xhci_hcd [252731.378816] usb 1-2: New USB device found, idVendor=03f0, idProduct=3d17, bcdDevice= 1.00 [252731.378834] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [252731.378840] usb 1-2: Product: HP LaserJet P1005 [252731.378845] usb 1-2: Manufacturer: Hewlett-Packard [252731.378850] usb 1-2: SerialNumber: BC0KF18 [252731.382168] usblp 1-2:1.0: usblp2: USB Bidirectional printer dev 29 if 0 alt 0 proto 2 vid 0x03F0 pid 0x3D17 [252735.087585] usblp2: removed
The device entry will disappear if you unplug or poweroff the device.
Now that devices are being detected, it's time to grab some additional software in order to print files to the printer. hplip, a printer library (released under the GNU Lesser General Public License), supports most USB printers, with some exceptions.
This was tested with the 3.23.12 version (from Sourceforge). In order to get it to compile, you'll need to compile and install hplip 3.23.12 first.
You need this even though USB support is in the kernel already.
Once libusb is installed, compile and install hplip following the instructions provided.
./configure; make; make install
On Ubuntu 24.04.3 LTS you can install hplip by doing
sudo apt install hplip
hplip provides a command line tool for operating some printing devices. After installation, check for USB support by doing
hp-setup
The output should be along the lines of:
to see the list of supported printers. Find the name of your printer, according to hplip. Now comes the exciting part, printing images.
Go into the directory that you wish to print images to, and type
If you see a message like 'Unknown port' from hplip, it either means that USB support didn't make it into a compile somehow.
The error message hplip reported the error 'error: No devices found on bus: usb' typically means that the USB printer isn't turned on or plugged in.
