Onscreen error messages appear

If the following messages appear onscreen, use the appropriate procedures to remedy the problem.

Printer not responding/error writing to LPT1

Check the following conditions:

●Is the device in the Ready state?

●Are the power cord and IEEE 1284-B-compliant parallel or USB Device Cable (A/B) correctly connected?

●Are other printer drivers installed on the computer?

Try the following remedies:

●Disconnect the power cord and the IEEE 1284-B-compliant parallel or USB Device Cable (A/B) at both ends and reconnect them.

●Use another IEEE 1284-B-compliant parallel or USB Device Cable (A/B).

●Make sure that another device or printer is not selected as the default printer.

Cannot access port (in use by another application)

A device conflict exists. This might occur if another device is installed on your computer and is running status software. The status software dominates the parallel port on the computer and denies the device access to the port.

Try the following remedies:

●Disable all of the status windows for other devices.

●Make sure that the device port setting is correct. Change the port settings on the Details tab or the Ports tab in the device properties.

●Make sure that bidirectional support is disabled for the device. On the Details tab or the Ports tab in the device properties, make sure that the bidirectional support option is not selected.
