For example, if you are using a printer via a USB or network connection and receive the error message "There was an error writing to LPT1", this would indicate that the print data has been sent to a port that Windows reserves for printers connected via a Parallel interface. Some users may receive an error message that indicates an issue with the port settings. In order to communicate and print successfully, the port setting in the printer driver software must be set correctly. A port is an interface channel used for transferring data from the computer to a printer.


If the printer has failed to respond to a print command, the printer driver port may not have been configured correctly.
