How to Choose: OEM vs Compatible Toner—What’s the Difference? When selecting a toner for printer Oki B731, the key decision is usually between original OEM and compatible toner. Here’s the practical difference: - Original OEM toner (like 45439002) is produced to the printer manufacturer’s specification. It’s often chosen for maximum predictability and for environments where standardization is important.
- Compatible toner is an alternative designed to match the performance and fit of the original. In our DrTusz.pl offer, compatible cartridges are created to deliver print quality and reliability that are as good as original cartridges—an excellent option if you want strong results while optimizing printing costs.
Our advice: if you print critical documents daily and want to stay closest to manufacturer parameters, choose OEM.
