SATO's WD-series model numbers look cryptic, but they follow a simple pattern once you know it: the first digit set is resolution, the second is configuration.
| Model | Resolution | Configuration |
|---|---|---|
| WD202 | 203 DPI | Base model |
| WD212 | 203 DPI | Cutter or dispenser option |
| WD302 | 300 DPI | Base model |
| WD312 | 300 DPI | Cutter or dispenser option |
203 DPI vs 300 DPI: which do you need
203 DPI (WD202/WD212) is the standard resolution for most shipping labels, warehouse labels, and general barcode printing, and is typically the lower-cost option. 300 DPI (WD302/WD312) prints finer detail, which matters for small text, dense 2D barcodes, or compliance labels with tight legibility requirements.
Base model vs cutter/dispenser configuration
The WD212 and WD312 add a cutter or label dispenser to the same core printer as the WD202 and WD302 — useful if you need individual pre-cut labels or automatic label presentation rather than a continuous roll.

Frequently asked questions
What's the difference between SATO WD202 and WD302?
The WD202 prints at 203 DPI, while the WD302 prints at 300 DPI for finer detail. Both are part of the same SATO WS4 desktop printer series with a 4.09-inch max print width.
What's the difference between WD202 and WD212 (or WD302 and WD312)?
The second-digit variants (WD212, WD312) indicate configured versions with a cutter or dispenser option, while the base models (WD202, WD302) ship without that hardware.
Do I need 203 DPI or 300 DPI?
203 DPI is standard for most shipping and warehouse labels and is typically less expensive. 300 DPI is worth the upgrade for small text, dense barcodes, or labels that need finer print detail.
Do you buy back used SATO printers?
