LPT2USB™ has two models, the more popular model (which can be purchased through the website) is DB25-LPT2USB™ (XR00027). It has a DB25 connector and can be connected to the printer with a USB cable.
LPT2USB™ is a parallel to USB adapter - sophisticated device that enables connecting a parallel port of a host system, either a computer or a computer embedded system, to a USB port of a printer. LPT2USB™ solves a well-known and widespread problem of legacy systems that for printing require a connection to the printer via a parallel port. This may be the result of a legacy hardware system that has only a parallel printing port, or a legacy software system that was designed for parallel port printing. Most modern peripheral devices, such as low-cost printers, do not have a parallel port.
LPT2USB™ is a low cost, long life, plug-and-play connecting device that enables legacy systems to connect via their parallel port to the USB ports of printers. LPT2USB™ works with any host with a parallel port, and it is hardware and software independent. LPT2USB™ takes by default the power supply from the host keyboard. The LPT2USB™ (XR0017) model is embedded in a metal packaging device. It has a USB connector and a power socket on the front panel, and a 36-pin Centronics female socket on the back panel. It connects to any standard printer parallel cable.

LPT2USB - parallel to USB adapter, detailed description
- By a keyboard adaptor, which connects to the PC keyboard port (while still allowing the connection of the keyboard to the host).
- By a USB cable, which connects to a USB host port (when available).
- By an AC-to-DC power supply. Uses 5VDC to 12VDC power supply, 150 milliamps or more. The positive pole is the inside hole. This option should be ordered separately from the local distributor or from ePaper Sales.
LPT2USB parallel to USB adapter - works out-of-box and does not require any additional configuration.

LPT2USB parallel to USB adapter - works with any machine and any operating system that meets the following requirements:
- Any host that has a parallel port with IEEE-1284 1994 (bi-directional parallel interface) specification compliant.
- The host should be able to send data that is recognized by the printer. For example, if the printer language is HP PCL Level 3, the application should be able to send a print file that is HP PCL Level 3.
- Connect the power supply cable (or power cable keyboard or USB to the round power socket).
- Plug the device to the PC DB25 parallel port connector.
- Connect a USB cable between the USB A connector on the unit and the USB B connector on the printer's panel.
- Connect the power supply to the mains power supply, or, if using keyboard or USB cables for power supply, connect it to the keyboard or USB sockets.
The unit comes with a one-year conditional warranty.

Some new USB printers may accept data received only from the original printer driver. Upon receiving incompatible data they print nothing, unlike older generation printers that print garbled data. Please make sure that you send data compatible with the printer or that you purchase a printer that accepts the format of the data you are printing.
DOS and legacy applications often generate ASCII data. For printing ASCII data with a modern HP printer, the printer must support HP PCL, and ESC/P or ESC/P2, in addition to graphics/raster. Information on the data formats supported by a specific printer is provided in the printer specifications. The printer manufacturer's website usually lists the information under "language support." Before buying a printer that you plan to use with DOS or Windows character applications, ask for printers that support ASCII data. To test if your printer works with DOS or legacy character applications, send ASCII data to your printer, e.g., using the SpoolFile application.
