<h1>Homebox Label Generator</h1>
<p>
The Homebox Label Generator is a tool to help you print labels for your Homebox inventory. These are intended to
be print-ahead labels so you can print many labels and have them ready to apply
</p>
<p>
As such, these labels work by printing a URL QR Code and AssetID information on a label. If you've disabled
AssetID's in your Homebox settings, you can still use this tool, but the AssetID's won't reference any item
</p>
<p>
This feature is in early development stages and may change in future releases, if you have feedback please
provide it in the <a href="https://github.com/hay-kot/homebox/discussions/273">GitHub Discussion</a>
</p>
<h2>Tips</h2>
<ul>
<li>
The defaults here are setup for the
<a href="https://www.avery.com/templates/5260">Avery 5260 label sheets</a>. If you're using a different sheet,
you'll need to adjust the settings to match your sheet.
</li>
<li>
If you're customizing your sheet the dimensions are in inches. When building the 5260 sheet, I found that the
dimensions used in their template, did not match what was needed to print within the boxes.
<b>Be prepared for some trial and error</b>
</li>
<li>
When printing be sure to:
<ol>
<li>Set the margins to 0 or None</li>
<li>Set the scaling to 100%</li>
<li>Disable double-sided printing</li>
<li>Print a test page before printing multiple pages</li>
</ol>
</li>
</ul>
