In Windows printing architecture, before an application sends actual page content to the printer, it must start a “print job” using a function called StartDocPrinter . This function tells the print spooler: “A new document is coming; prepare the printer and allocate resources.” If the system tries to send data (e.g., a page’s graphics or text) without first calling StartDocPrinter , Windows blocks the operation and returns this error. Essentially, the print job’s “handshake” failed—the printer received data but missed the official opening command.
