Bulk Label Printing

Overview

The Bulk Label Printing feature allows you to generate and print QR code labels for multiple inventory items simultaneously. This feature is essential for efficiently deploying a QR code-based inventory system across your warehouse or facility.

Key Benefits:

  • ⚡ Time Savings: Generate hundreds of labels in minutes instead of hours

  • 🎯 Selective Printing: Filter items by category, location, or status

  • 👁️ Preview First: Review all labels before committing to print

  • 📄 Print-Optimized: Labels automatically format for A4 paper (3 per row)

  • 🏷️ Complete Information: Each label includes QR code, name, SKU, location, and description

Using the Label Printing Feature

Step 1: Select Filters

The first step is to filter which items you want to print labels for.

Category Filter

Filter items by their assigned category:

  1. Click the Category dropdown

  2. Select a specific category (e.g., “Electronics”, “Chemicals”, “Consumables”)

  3. Or select “All Categories” to include items from all categories

Example: Print labels only for “Office Supplies” category items.

Location Filter

Filter items by their physical location:

  1. Click the Location dropdown

  2. Select a specific location (e.g., “Lab-A-Shelf-3”, “Storage-Room-2”)

  3. Or select “All Locations” to include items from all locations

Example: Print labels for all items in “Lab-B” to reorganize that laboratory.

Tip

Location Naming Convention: Use a consistent format like Room-Section-Shelf (e.g., Lab-A-Shelf-3) for easier filtering and organization.

Status Filter

Filter items by their active/inactive status:

  • All: Include both active and inactive items

  • Active Only: Only include items currently in use (default)

  • Inactive Only: Only include items that have been deactivated

Recommendation: Use “Active Only” to avoid printing labels for discontinued items.

Item Count Badge

As you adjust filters, the item count badge updates in real-time showing how many items match your criteria:

[42 items match your filters]

Example: If you select Category=”Electronics” and Status=”Active”, you might see “23 items match your filters”.

Step 2: Generate Labels

Once you’ve configured your filters, generate the QR code labels.

  1. Review the item count to ensure you’re printing the correct number of labels

  2. Click Generate Labels button

  3. A loading spinner appears with “Generating…” text

  4. QR code generation occurs (typically 5-10ms per item)

  5. A success toast notification appears when complete

Best Practices

Planning Your Label Deployment

1. Inventory Audit First

Before printing labels, audit your inventory to ensure:

  • All items have accurate locations

  • SKUs are unique and correct

  • Descriptions are complete

  • Inactive items are marked inactive

2. Print in Batches

Instead of printing all labels at once:

  • Print by category or location

  • Verify first batch scans correctly

  • Adjust label format if needed

  • Continue with remaining batches

3. Label Organization

After printing:

  • Cut labels carefully

  • Organize by location before applying

  • Keep extras for replacements

  • Store unused labels in a dry, dark place

Label Application

Placement Guidelines:

✅ Do: - Apply labels to flat, clean surfaces - Use the same placement on all items (consistency) - Apply at eye level when possible - Keep labels away from moisture/heat - Ensure QR codes are not folded or creased

❌ Don’t: - Apply labels to curved surfaces (QR codes may distort) - Cover labels with tape or plastic (reflections interfere with scanning) - Apply in direct sunlight (labels fade faster) - Apply to dirty/greasy surfaces (labels won’t stick)

Adhesive Options:

Testing QR Codes

After applying labels, test QR code scanning:

Method 1: Smartphone Camera

  1. Open your phone’s camera app

  2. Point camera at QR code

  3. Tap the notification/banner that appears

  4. Verify it displays the correct SKU

Method 2: LUStores Scanner

  1. Navigate to Sales page in LUStores

  2. Click Browse Items tab

  3. Click Scan Barcode button

  4. Point camera at QR code

  5. Verify item is added to quote with correct details

Method 3: Dedicated Scanner

  1. Configure scanner to output as keyboard input

  2. Click in a text field

  3. Scan QR code

  4. Verify SKU appears in the text field

If scanning fails, see Troubleshooting section.

  4. Improve Lighting: QR codes need adequate lighting to scan

    • Avoid shadows over the QR code

    • Avoid glare from overhead lights

    • Use indirect lighting

  5. Check QR Code Integrity: Ensure QR code is not damaged

    • No folds or creases

    • No marks or stains

    • Not covered by tape or lamination with glare

Labels Per Row Incorrect

Symptoms: - Labels not aligned in 3-column layout - Labels cut off at page edges - Uneven spacing between labels

Solutions:

  1. Browser Print Settings:

    • Set paper size to A4 (210mm × 297mm)

    • Set margins to Default (5mm)

    • Set scale to 100% (no scaling)

    • Disable “Headers and Footers”

    • Disable “Background Graphics” (optional)

  2. Printer Configuration:
