- Create a new label stock for your printer
First, create a new default label stock for your printer. In the printer settings, click 'New' in the Stock drop-down options to define a custom paper size. This ensures the printer knows the exact dimensions of your DPD labels.
- Set the correct label dimensions
Set your label dimensions to match the DPD requirements exactly: - Width: 4.17in (106mm) - Height: 4.02in (102mm) - Left Margin: 0.05in (1.27mm) - Right Margin: 0.05in (1.27mm) These measurements are critical for DPD label validation, so enter them precisely.
- Print your labels from the browser
From your browser's standard print dialogue (tested on Chrome Windows and Firefox Windows), select the custom paper size you just defined. Make sure that 'Fit to page' is turned on, then click the Print button. Note: the recommended print dialogue reference image is based on Chrome's interface.
- Validate the printed labels
DPD are very strict on label validation, so you must double-check your printed labels before submitting for approval. Use a ruler to verify the following: - The barcode must be a minimum of 91.5mm wide by 25mm high - The space between the label edge and the barcode must be at least 5mm Do not submit labels for approval until you have physically measured them and confirmed they meet these requirements.
Frequently Asked Questions
Why do I need to create a custom label stock for the Citizen CLP-521?
The Citizen CLP-521 needs a custom stock size defined so it prints at the exact dimensions DPD requires. Without a correctly sized stock, the label content may be scaled incorrectly, causing barcodes to fall outside DPD's strict measurement tolerances. Creating a named custom stock also makes it easy to reuse the correct settings every time you print.
What browsers can I use to print DPD labels on the Citizen CLP-521?
The settings in this guide have been tested and confirmed to work on Chrome (Windows) and Firefox (Windows). The print dialogue screenshots reference Chrome, but the process is the same in Firefox. Other browsers may work but have not been officially tested.
What happens if my printed barcode doesn't meet DPD's size requirements?
DPD will reject labels that do not meet their barcode validation standards. The barcode must be at least 91.5mm wide by 25mm high, and there must be at least 5mm of clear space between the barcode and the label edge. Always measure your test labels with a ruler before submitting them to DPD for approval.
Do I need to enable 'Fit to page' when printing?
Yes, 'Fit to page' must be enabled in the browser print dialogue. This ensures the label content is scaled correctly to fill the custom stock size you defined. Without it, the label may print at an incorrect scale, causing the barcode dimensions to fall outside DPD's requirements.
Can I use a different thermal printer instead of the Citizen CLP-521?
This guide is specifically configured for the Citizen CLP-521. Other thermal printers may require different stock dimensions or driver settings. If you are using a Zebra GK420D, refer to the dedicated Zebra setup guides available in the help centre for the correct configuration.
