How to Fix Zebra ZT230 Word Mail Merge Paper Size & Barcode Errors
Question details
The user is encountering paper size mismatch errors and missing barcodes when attempting to print labels using Word Mail Merge with a Zebra ZT230 printer.

- Product
- Microsoft Word, Zebra ZT230 Printer
- Device & OS
- not provided
- Scenario
- Using the Mail Merge feature in Word to print barcode labels to a Zebra ZT230 thermal printer.
- Observed behavior
- Word displays a document section size error indicating it differs from the printer page size, and barcodes do not appear on the labels even when a barcode font is selected.
Ensure your Zebra ZT230 printer drivers are up to date and that your Windows printer preferences are configured with the exact label dimensions currently loaded in the printer.
Merge to Individual Documents Before Printing
Merging records into a new document instead of printing directly to the printer often bypasses page size mismatches and forces barcode fonts to render properly.
When Word attempts to print a mail merge directly to a specialized thermal printer like the Zebra ZT230, communication issues regarding page dimensions and custom fonts frequently occur. Generating the output as a standard Word document first allows the system to render the barcode fonts completely and format the pages accurately.
In Microsoft Word, navigate to the 'Mailings' tab on the top ribbon and click on 'Finish & Merge' in the final section.
Select 'Edit Individual Documents...' from the drop-down menu. When the prompt appears, choose 'All' and click 'OK' to generate a new document containing all of your merged labels.
In the newly generated document, press 'Ctrl + P' or go to 'File' > 'Print' to open the Print Preview screen. Check carefully to ensure your barcode fonts are now visible on the labels.
Verify that the selected printer is your Zebra ZT230 and that the page size in the print settings matches your physical label stock. Click 'Print' to produce your labels.
If the error occurs again, go to 'File' > 'Account' to document your specific Office version and product information, which will be helpful for further troubleshooting.

Print Labels Seamlessly with WPS Office
If Microsoft Word continues to struggle with your Zebra ZT230 printer, try WPS Office. It provides a lightweight, highly compatible alternative with a robust Mail Merge feature that handles custom paper sizes and barcode fonts effortlessly.
- 1. Open your label template in WPS Writer: Launch WPS Office and open your existing Word label template document without worrying about formatting loss.
- 2. Set custom page dimensions: Go to 'Page Layout' > 'Size' > 'More Paper Sizes' and input the exact width and height of your Zebra printer labels.
- 3. Execute Mail Merge: Navigate to the 'References' tab, click 'Mail Merge', connect your data source, and merge to printer to generate your barcode labels accurately.

Frequently Asked Questions
Why are my barcode fonts not printing in Word Mail Merge?
Barcode fonts may fail to print if they are not properly embedded, if the printer driver does not natively support them, or if direct mail merge bypasses the font rendering engine. Merging to a new document first usually forces the font to render on the page before it is sent to the printer spooler.
How do I fix the 'section size differs from printer page size' error?
This error is triggered when your document's Page Setup dimensions do not exactly match the paper size selected in your Zebra printer preferences. Ensure that both Word's Page Layout settings and the Zebra printer driver settings have identical label width and height configurations.
Can I use WPS Office to print labels to a Zebra ZT230 printer?
Yes, WPS Office fully supports standard Windows printer drivers, including Zebra thermal printers. You can set custom page sizes in WPS Writer to match your specific label stock and execute Mail Merges to print barcodes without formatting issues.
