Which printer model and operating system you are using, without these details I can give you some general troubleshooting steps:
(A) Please disconnect the printer from the computer and first clear the error state, it may be paper jam, no ink etc so accordingly act.
(B) Restart the printer, if the light is still blinking the issue is not gone so try again.
(C) In the computer, clear the print requests.
(D) Delete any ghost/duplicate printers.
(E) Update the printer software from the manufacturer’s website.
(F) Check if the spooler services are running.
(G) Reconnect the Printer once light is stable and try to print.
