About Printing QR Codes

Sticky labels and plastic placards with QR codes can be created to be placed on devices or near systems, making it very easy to find key documentation for that device or system.

Scanning a QR code

If you see a QR code label or placard on or near a device or system of interest, simply open the camera app on your phone and point the camera at the QR code such that the entire QR code is in the frame. You will have better results if the code fills a significant portion of the camera frame and is reasonably well focused. When the software recognizes and decodes the QR code, it will draw yellow lines around the corners of the code and display a yellow button at the bottom of the camera’s view. Tapping that button opens the internet browser and displays documentation for the device or system.

The following QR code label image, when scanned, will open the browser on your phone, and take you to this page on the home documentation website. Give it a try.

If all you want to do is use a QR code found around or home to find information about whatever it is that has one on it, you’re done here. Read on if you want to print a QR label or 3D print a placard then read on.

Generating and Printing QR Codes

Prerequisites

If you want to print a sticky label or 3D print a placard, you will first need to know how to use the Obsidian editor to edit the vault that contains the source code for this documentation. Read about how to do that, then come back here.

Labels can be placed conspicuously or hidden away under or on the back of a device. In any case, they should be placed so that it is reasonably easy to scan the QR code with a phone. If it is placed so that it is (mostly) out of plain sight, the device will need to be picked up and temporarily oriented to scan the QR code. Choose a placement that allows for reasonably easy use, while not being unacceptably tacky and gawdy.

Plackardstor labels representing a system might typically be placed on a key device of that system, or on a wall, for example, near a cluster of devices that ar pe part of that dystem.

  • Sticky labels, printed using the Brother QL700 label printer in the Lab, are intended for placement on devices inside the building.
  • 3D printed placards, created using the 3D printer, are intended for placement outside.

a specific device or near t while editing the documentation vault using Obsidian. The labels and placards are stuck/glued to selected devices and systems in order to make it as simple as possible to see specific documentation about the device or system to which the QR Code is affixed.
