Simple Accounting automatically checks the status of the selected printer port before allowing you to print. If a problem is indicated when selecting a printer port, check to see that the printer is turned on, is on-line and that the printer cable is securely attached at both the computer, and printer, ends. If you are using this program on a network, check that you are properly logged in, and linked to the server’s printer. If these steps don’t solve the problem, there may be a hardware problem.
