Key Advantages

The OKI Microline 490 boasts exceptional reliability for continuous, heavy-duty printing tasks in office environments. Its 24-pin print head produces high-quality text and detailed graphics, surpassing earlier dot matrix models. Multiple interface options facilitate seamless integration with existing legacy computer systems. The printer's ability to handle multipart forms efficiently makes it ideal for invoicing and receipt printing. Its compact design saves desk space while maintaining ruggedness for longevity. Additionally, its relatively low operating cost and ease of maintenance contribute to its enduring popularity.

Limitations

The OKI Microline 490 is limited by lower resolution compared to modern inkjet and laser printers, resulting in less sharp text and graphics. Its print speed, while competitive in its category, is slower than contemporary digital printers. The printer is noisy during operation, which may be disruptive in quiet office settings. It lacks advanced connectivity options such as USB or network interfaces common in later models. Color printing capability is absent, restricting output to monochrome only. Finally, its size and weight are bulkier compared to new compact printing solutions, making portability a challenge.
