Key Advantages

The Microline 320 offers excellent print durability due to its impact technology, suitable for multipart forms. It provides versatility with multiple interface options including parallel and serial ports. The printer supports a variety of paper types including continuous tractor-fed forms, making it highly flexible. Its competitive print speed of approximately 240 cps helps reduce print job times. The device's simple mechanism and fewer moving parts contribute to a low maintenance requirement and longer lifespan. Additionally, availability of compatible spare parts and accessories supports field servicing and longevity.

Limitations

Being an impact printer, the Microline 320 produces lower print resolution compared to modern inkjet or laser printers, limiting graphic quality. The noise level during operation is higher relative to quieter thermal or laser technologies. It mainly supports monochrome printing, restricting color document needs. Limited internal memory and printing speed may not meet the demands of high-volume, fast-paced modern office environments. The printer requires continuous tractor-fed papers, limiting the use of standard cut-sheet paper formats. Additionally, the technology is largely outdated, making driver compatibility with current operating systems challenging.
