If you are using a cable to connect an old printer to a USB port, you likely need a specific chipset driver rather than a printer driver: CH340/CH341 Chipsets : Common in affordable adapters. Download drivers from WCH Official Prolific PL2303 : Found in many brand-name adapters. Download from the Prolific Technology Official Site Google Groups

It is important to understand exactly what this hardware is before downloading files.

: A common manufacturer for generic POS/thermal printers often found in COM/LPT searches.

You can verify the driver match by checking the "Details" tab in Device Manager; for this card, the hardware ID usually begins with PCI\VEN_13FE&DEV_1711 .

Right-click the problem COM/LPT controller and select . Choose Browse my computer for drivers .

In the history of personal computing, COM (Communications) and LPT (Line Print Terminal) are foundational, yet archaic, interfaces. COM ports (serial ports, RS-232) were used for mice, modems, and industrial equipment. LPT ports (parallel ports, IEEE 1284) were the standard for printers and some external drives like the Zip drive. A driver for a "COM LPT" device would theoretically manage a piece of hardware that combines both serial and parallel functionalities—an extreme rarity outside of specialized industrial PCIe/ISA expansion cards.

After a successful installation, you may need to adjust settings:

If you are setting up storage, you might be looking for Intel® Rapid Storage Technology (Intel® RST) Driver 17.11.3.1010.2 . 2. Top Sources for Com LPT 1711 Driver Download

Some legacy apps require specific IRQ (e.g., IRQ 7 for LPT1). Set this in BIOS or via Device Manager → Resources tab.

After the installation finishes, restart your computer to ensure the driver is active. Installing/Fixing COM Port Drivers (Windows 10/11) If the port does not appear:
