A message `Printer not available' indicates that either there is no printing capability, or the printer is not connected or the printer has not been turned on.
If the printer is turned off during printing, or when it runs out of paper one may get the message "Printer not ready. Continue ? (Y/N)". This will enable you to add paper or turn the printer back on again before telling stedi to continue. The answer n or N will abort the printing.
