The cost of a desktop UV printer does not end when the machine is purchased.
For a small business, ongoing expenses can include ink, maintenance, materials, replacement components, and production time.
That makes the ink system an important consideration when comparing LONGER ePrint and xTool O1 Omni.
One of ePrint’s most distinctive advantages is its open ink system, combined with dual-head production and a broad range of printing applications.
1. Open Ink Gives Businesses More Choice
LONGER ePrint supports compatible third-party inks.
By contrast, xTool states that O1 does not support third-party inks.
For businesses that prefer a controlled closed ecosystem, a dedicated ink system may be straightforward.
For experienced users who want more control over consumable sourcing, however, an open system offers another option.
A business could begin with official LONGER inks and later evaluate compatible third-party options according to its specific application and production requirements.
2. Why Ink Choice Matters to a Small Business
Imagine a business producing hundreds of personalized products every month.
At that point, ink is no longer a minor expense.
The business may want to compare:
- Ink cost
- Ink consumption
- White-ink usage
- Cleaning requirements
- Availability
- Supplier lead times
- Finished print quality
An open ink system allows experienced users to evaluate more variables.
It does not guarantee lower costs, but it provides more freedom when optimizing the production workflow.
3. Dual Printheads Add Another Layer of Efficiency
ePrint combines its open ink architecture with dual Epson F1080 printheads and 12 ink channels in its dual-head configuration.
LONGER states that the dual-head setup can achieve up to 2× faster 2D printing and up to 6× faster 3D texture printing compared with a single-head configuration.
This means businesses can evaluate two important parts of ownership together:
How much flexibility do I have over consumables?
and
How efficiently can I produce customer orders?
4. 15 mm Relief Can Increase Product Value
Operating cost is only one side of the equation.
The other is what the business can charge for its products.
ePrint supports up to 15 mm color relief, allowing businesses to create more tactile products.
For example, a standard acrylic sign could become a raised-logo sign. A wooden decoration could receive dimensional lettering. A personalized gift could use faux embroidery effects.
The printer therefore provides opportunities to create products that are visually and physically different from flat prints.
5. High-Gap Printing Can Expand the Product Range
ePrint also supports up to 10 mm high-gap printing.
This can be useful for suitable products with uneven surface heights.
Instead of limiting the product catalog to perfectly flat objects, a business can test shaped or contoured products.
This can be particularly useful for custom-product businesses constantly looking for new items to add to their catalog.

Conclusion
When comparing a UV printer, the purchase price is only one part of the calculation.
The long-term picture also includes consumables, production efficiency, and the types of products the machine can support.
LONGER ePrint combines an open ink system with dual Epson F1080 printheads, 12 ink channels, up to 15 mm color relief, and 10 mm high-gap printing.
For experienced small-business users who value consumable choice and production flexibility, these features provide additional room to optimize the way they operate.
