Error: You print a PDF document on your Lexmark Printer ( MS317DN in my case which is based on best selling MS320) , and get a message “Flushing Buffer” on the LCD Screen.
Quick Resolution : Print the Document as ” Print as Image”
This is caused mostly by corrupt or incompatible PS settings in the PDF you are trying to print. You may get to print after clearing the print queue, but in my case, it would never print a particular file ( a bank statement). Finally, I realized that if I print it as an Image instead of PDF, there is no language setting going to the printer and it worked.
