# This label class provides attributes for Bioscan tube labels. The labels have
# two stickers, side and cap.
#
# The side contain a 2D barcode image and four text lines.
# * The barcode image contains human barcode.
# * The first line contains parent barcode and well range for PCR2 Pool tube
#   and only the parent parcode for others.
# * The second line contains current tube barcode without prefix and number of
#   pooled samples, the third line contains the labware purpose.
# * The third line contains current tube labware purpose
# # The last line contains date of printing.
#
# The cap contains two text lines.
# * The first contains barcode prefix.
# * The last contains current tube barcode without prefix.
#
# Initially, this arrangement was only intended for Traction compatibility of
# Lib PCR XP (final) tube. However, difficulty of printing 1D barcodes for PCR2
# and Lib PCR tubes made us using 2D barcodes for all three Bioscan tubes.
#
# Only Squix printers are used for printing labels for Bioscan labware from
# Limber. We do not send the print requests to PMB service, instead we send them
# directly to SPrint service, which talks to Squix printers.
