Solving Barcode Printing Issues in RDLC Reports – Business Central On-Premise (v25)

When working with barcode printing in RDLC reports on Microsoft Dynamics 365 Business Central On-Premise, I recently ran into an issue that had me stumped for hours — and as it turns out, it all came down to a subtle but critical font installation step.

If you’re using Business Central and your barcodes refuse to show up in your reports (even after installing the right fonts), read on — this might just be your solution.

The Problem: Barcode Fonts Not Showing in RDLC

Here’s what I tried — the standard advice you’ll find across most forums:

• Installed the barcode font (Code 128, Code 39, Free 3 of 9, etc.) on the service tier machine
• Installed the same font on the user/client machine
• Restarted the Business Central Server/NST
• Restarted the entire machine
• Checked that RDLC reports were using the correct font name

Still — no barcodes were rendered.

The Hidden Detail: “Install for All Users”

After much trial and error, I stumbled across the real fix:

When installing a font on the Business Central service tier (server), you must choose “Install for all users” — not just a regular install.

Here’s why:

• Business Central’s NST runs under a system account, not your logged-in user.
• Fonts installed only for the current user aren’t visible to the NST process.
• Unless the font is registered system-wide, RDLC won’t be able to use it.

Install the Barcode Font on the Server

• Right-click the font file (e.g., Code128.ttf)
• Choose Install for all users

Install the Font on Client Machine (Optional but recommended)

• This ensures previews and printed reports render properly when opened locally.

Restart the Server

• Not just the NST service — a full restart helps Windows fully register system fonts.

It’s always the little things! A simple checkbox — “Install for all users” — was all it took to fix what seemed like a mysterious RDLC issue.

If you’re working with barcode fonts in RDLC reports on Business Central and nothing seems to work, double-check your font installation method — this could save you hours of frustration.

Hope this will help!!!
