Ethernet connections enable network printing, allowing multiple users to share a single printer, a feature lacking in the point-to-point architecture of parallel connections. The lack of widespread support for parallel ports on modern computers has further contributed to their decline.
What are the main advantages of using a parallel printer compared to modern printers?
While parallel printers are considered outdated, there are a few specific scenarios where they might offer advantages, primarily revolving around legacy hardware and niche industrial applications. Firstly, compatibility with older systems is a major reason. If you have a legacy computer system or industrial equipment that relies exclusively on a parallel port for communication, a parallel printer might be the only option for printing from that system without requiring potentially unstable or complex adapters. Secondly, in certain controlled environments, the simplicity and directness of a parallel connection can be viewed as a security advantage, as it minimizes the attack surface compared to network-connected devices.
However, it’s essential to weigh these advantages against the significant drawbacks. Modern printers offer superior speed, image quality, feature sets (such as duplex printing and wireless connectivity), and driver support. Furthermore, the cost of maintaining a parallel printer, including sourcing compatible cables and drivers, can outweigh the perceived benefits, especially when considering the availability of USB-to-parallel adapters that, while not always perfectly reliable, provide a potential bridge to modern systems.
Is it possible to connect a parallel printer to a modern computer that only has USB ports?
Yes, it is generally possible to connect a parallel printer to a modern computer with only USB ports using a USB-to-parallel adapter cable. These adapters typically have a USB connector on one end that plugs into the computer and a Centronics 36-pin connector on the other end that plugs into the parallel port of the printer. These adapters work by converting the USB data stream into a format that the parallel printer can understand.
However, it’s important to understand that the compatibility and performance of these adapters can vary. Not all adapters are created equal, and some may not work reliably with all parallel printers or operating systems. Driver support is crucial; the adapter must have compatible drivers for your operating system (Windows, macOS, or Linux) to function correctly. It’s advisable to check user reviews and product descriptions carefully before purchasing an adapter, and to ensure that the adapter is specifically designed for printer use (some adapters are designed for other parallel devices).
What should I consider when choosing a USB-to-parallel adapter for my printer?
When choosing a USB-to-parallel adapter, compatibility is paramount. Check if the adapter explicitly states compatibility with your specific printer model or a similar model within the same brand family.

These problems often stem from driver conflicts, unsupported printer models, or limitations in the adapter’s data conversion capabilities. Some adapters may also struggle with bidirectional communication, preventing the computer from receiving printer status information.
Another common issue is slow printing speeds. While USB is generally faster than parallel, the conversion process introduced by the adapter can create a bottleneck. The adapter may not be able to process data quickly enough to keep up with the printer’s printing speed, resulting in slower performance. Additionally, power delivery can sometimes be a problem, especially with older printers that draw a significant amount of power from the parallel port. In these cases, using a powered USB hub may help to provide sufficient power to the adapter and printer.
Are there specific printer types (e.g., laser, inkjet, dot matrix) that are more or less likely to work well with parallel-to-USB adapters?
Generally, simpler printer types like dot matrix printers are more likely to work well with parallel-to-USB adapters compared to more complex printers like laser or inkjet printers. Dot matrix printers often use a simpler command set and data format, which reduces the likelihood of compatibility issues with the adapter’s data conversion process. Their reliance on older, more standardized protocols also means the emulated parallel communication via the adapter is less likely to encounter unexpected behavior.
Laser and inkjet printers, on the other hand, often utilize more sophisticated command languages (like PostScript or PCL) and require bidirectional communication for status updates and error reporting. Adapters may struggle to handle these complex protocols correctly, leading to printing errors, incomplete prints, or a failure to communicate with the printer at all. Additionally, newer inkjet and laser printers often rely on proprietary driver features that may not be fully supported by generic USB-to-parallel adapters.
If I’m looking for a reliable printing solution for a legacy system, is purchasing a used parallel printer a better option than using an adapter with a modern printer?
The best option depends on several factors. If your primary concern is printing from a legacy system without modification, purchasing a used parallel printer that is known to be compatible with your system’s parallel port can be a more reliable and potentially less frustrating solution than using an adapter with a modern printer. This avoids the potential compatibility issues and performance limitations associated with USB-to-parallel adapters. However, finding a reliable used printer in good working condition may require some research and careful inspection, and you’ll need to ensure replacement parts and supplies (like ink or toner) are still available.
Conversely, while adapters can be problematic, choosing a well-reviewed adapter specifically tested with similar printers to your legacy system can sometimes work seamlessly. A modern printer, even with an adapter, might offer better print quality, faster speeds, and lower operating costs (especially in terms of ink or toner consumption) than a used parallel printer. Therefore, a good strategy is to fully research the available printers and adapters, looking for compatibility reports from other users with similar legacy systems, before making a purchase. Factor in the long-term costs of supplies and maintenance for both options to make an informed decision.
