# qr_labels

I was packing boxes and nerd-sniped myself by deciding I needed a labelling
|
|
|
|
|
and cataloguing system to help me keep track of what was there.
|
|
|
|
|
|
|
|
|
|
To do that I needed to print labels for boxes, and figured it might be useful
|
|
|
|
|
if they also had QR codes on them.

I thought there would be a simple online tool to create PDF pages of identical
|

|
|
|
QR labels, but apparently not.

# Synopsis
|
|
|
|
|
|
|
|
|
|
Generate a page with 6 labels, where the QR code represents the string
|
|
|
|
|
"hello world" and the printed label is the same,
|
|
|
|
|
|
|
|
|
|
qr_labels -code "hello world" -code-is-label -rows 3 -cols 2 -output labels1.pdf
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Generate a page with 24 labels, with the code being a URL and the text label
|
|
|
|
|
being a different string. Adjust the sizes of the code and the font and include
|
|
|
|
|
borders between each label:
|
|
|
|
|
|
|
|
|
|
qr_labels -code "https://www.youtube.com/watch?v=dQw4w9WgXcQ" -label 'innocent link' -rows 6 -cols 4 -size 30 -font-style BI -borders -font-size 20 -output labels2.pdf
