mixMasterLabels

Command-line Python tool to generate labels from a saved McMaster-Carr order webpage.

For each order item, it generates one label file containing:

• McMaster part number
• Description
• QR code pointing to the product page
• Product image from McMaster (if available from the saved page)

Use --qty if you also want the quantity printed on each label.

Install

python -m pip install -r requirements.txt

Usage

python mixmaster_labels.py /path/to/saved-order.html /path/to/output-dir --format pdf --label-size 4x2in
python mixmaster_labels.py /path/to/saved-order.html /path/to/output-dir --format png --label-size 100x50mm --dpi 300 --qty
python mixmaster_labels.py /path/to/saved-order.html /path/to/output-dir --format png --order-info
python mixmaster_labels.py /path/to/saved-order.html /path/to/output-dir --format png --image-fill

Arguments

• input_html: saved McMaster-Carr order webpage HTML file
• output: output directory, or a file path whose .png/.pdf extension selects the format
• --format: optional explicit format (png or pdf), otherwise inferred from extension
• --label-size: label dimensions (WIDTHxHEIGHTin or WIDTHxHEIGHTmm), default 4x2in (4"x2")
• --dpi: rendered label DPI (default 300)
• --order-info: include line number, qty, price, subtotal, PO, and order date
• --image-fill: zoom and center-crop the product image to fill the image box

Each label is written as its own file named partnumber.png or partnumber.pdf.

PDF and PNG output both create one file per order item.
