Here is a python script I wrote a while back that does something like
you want.. The QR code is a URL (https://example.com/stuff/rack/1) and
there is some txt  "rack 1" underneath it. It has been a while since I
wrote it, so it looks like gibberish to me.

from PIL import Image, ImageDraw,ImageFont
import qrcode

qr = qrcode.QRCode(
    version=3,
    error_correction=qrcode.constants.ERROR_CORRECT_Q,
    box_size=10,
    border=4,
    )

image  = Image.new( "RGBA", ( 410, 480 ) ,"white");

qr.add_data('https://example.com/stuff/rack/1')
qr.make(fit=True)

img = qr.make_image()
print img.size
image.paste(img, (0,0), img.convert("RGBA") );


draw = ImageDraw.Draw(image)
font = ImageFont.truetype("/usr/lib/cinelerra/fonts/arial.ttf",60)
#font = ImageFont.load_default()
txt = "rack 1"
draw.text((100, 410), txt, (0,0,0), font=font)


image.save("qr.png")
