Key Advantages
The MICROLINE 591 offers robust reliability and high endurance suitable for heavy-duty printing. Its ability to print on multipart forms is ideal for invoicing and receipt generation. The dot matrix technology allows for carbon copy printing, a feature unavailable on inkjet or laser printers. Its fast printing speed helps increase office productivity. The printer supports multiple emulations, making it compatible with diverse software and operating systems. Its energy efficiency and low maintenance costs contribute to overall operational economy.
Limitations
As an impact printer, the MICROLINE 591 produces lower resolution text and graphics compared to modern laser or inkjet printers. It is comparatively noisy during operation, which may not suit quiet office environments. The print speed and quality are limited by the 9-pin print head technology. Lack of color printing capability restricts its use to monochrome applications. It also lacks advanced connectivity options such as USB or network support commonly found in newer models. The physical size is larger than contemporary compact printers, requiring more desk space.
