A method is described to provide the user with timely feedback if the printer is suspected as not being online. On an IBM Personal Computer, if a program is running on PCDOS, and using DOS to write to the printer, if the printer is not online (ready), DOS can wait up to one minute before informing the application that the printer is not online. During this time, the program appears to be dead, since keystrokes cannot be processed. Several possible solutions present themselves: 1. Display a message before the first character is sent to the printer informing the user to be sure his printer is online. Remove this message when DOS returns successfully.
