Overview
If you are experiencing issues printing labels—such as nothing happening, incorrect alignment, or labels printing improperly—the fastest way to identify the issue is by checking the label PDF generated by Syncrostore.
This allows you to determine whether the issue is:
- A Syncrostore formatting issue, or
- A printer, driver, or browser issue
How Syncrostore Generates Labels
Syncrostore generates labels as a PDF file, where:
- Each label is placed on its own page
- The layout is pre-formatted for the selected label size
- What you see in the PDF is exactly what should be printed
The browser print preview is simply displaying this generated PDF.
If each label appears correctly on its own page in the PDF, Syncrostore has already produced a complete and accurate print file.
How to Tell Where the Issue Is
✅ If the PDF Looks Correct
- Each label appears on its own page
- Labels are aligned properly
- No gaps or spacing issues
- Print preview matches the PDF
This confirms Syncrostore has generated the labels correctly.
At this point, Syncrostore’s role in the printing process is complete.
Any issues after this point—such as:
- Nothing printing
- Labels printing too high/low
- Misalignment on physical labels
- Scaling or shifting
…are caused by your:
- Printer
- Printer driver
- Browser or system configuration
❌ If the PDF Looks Incorrect
- Visible gaps between labels
- Spacing or alignment issues
- Content cut off or formatted incorrectly
This indicates a Syncrostore issue.
Please contact support and include:
- A screenshot or copy of the generated PDF
- The label type/size you are using
Example of a Correct Label PDF
Below are examples of a correctly generated labels from Syncrostore.
When the label appears correctly formatted in the PDF (no gaps, proper alignment, one label per page), it confirms that Syncrostore has completed its portion of the process successfully.
Any issues that occur after this point are related to printer configuration, drivers, or browser behavior.
Incorrect labels with objects misplaced
Incorrect labels will have misplaced text, barcodes or prices.
If the issue is visible directly within the PDF (before printing), this indicates a formatting issue within Syncrostore and should be reported to support.
Common Causes of Printing Issues (When PDF Is Correct)
- Outdated or unsupported Zebra printer drivers
- Older or discontinued Zebra printer models
- Browser compatibility issues (especially Chrome updates)
- Incorrect label size or printer configuration
- Print scaling settings (e.g., “Fit to Page”, "Fit to Printable Area" enabled)
- Differences between Mac and Windows environments
Troubleshooting Steps
If your PDF looks correct but printing is not:
- Reinstall or update your printer driver
- Print a standard PDF outside of Syncrostore
- Ensure scaling is set to 100% (no “Fit to Page”)
- Try a different browser
- Verify label size and printer settings
- Contact Zebra support or a local IT professional if needed
