Some of the Application Software use LPT1 port for printing the output like Receipts or reports.
But the Latest PCs not coming with the LPT1 / Parallel Port inbuilt.
So how to solve this?
We can use the USB Printer as LPT 1 Printer

Step 2: Type the command
Net Use LPT1: \\YourComputerName\USBPrinterShareName /PERSISTENT:YES
Dont forget to type PERSISTENT:yes , otherwise the setting will change on next boot.
Another method is
Assign the LPT1 port to your USB port
1) Close all programs
2) Click on the “Windows” – “Start” button
3) Choose “Run”
4) Type in “CMD” and press enter
Note: You should now be at what’s called the “DOS” prompt,
which is a black and white screen.
Note: You will need to know the name of your USB port. Follow steps 1 through 7 above “In Windows” to get the USB port name. Your USB port name will be similiar to USB01PORT. Step 5 below uses the example USB01PORT name. You will need to substitute your actual USB port name.
5) Type in: NET USE USB01PORT LPT1
6) Press the enter key.
