SYMPTOMS

When you print a map or a table to a Canon Bubblejet printer connected to an Enhanced Capability Port (ECP), the document may not print completely.

If you change the Canon printer to a different emulation mode, you receive the same results. This problem is known to occur with the following printers:
  • Canon BJC-4000
  • Canon BJC-70
  • Canon BJ-30
  • Canon BJ-200
NOTE: This problem may occur with other printers as well.

CAUSE

Windows sends data through to the ECP port too quickly for the printer to handle.

RESOLUTION

To correct this problem, follow these steps:
  1. Configure the port so it is not bidirectional in the computer's CMOS settings. For information about changing CMOS settings, please consult the computer's documentation or manufacturer.
  1. Delete the port in Device Manager. To do so, follow these steps:
    1. In Control Panel, double-click the System icon.
    2. On the Device Manager tab, double-click Ports (COM & LPT).
    3. Click ECP Print Port (LPTx), and then click Remove.
    4. Click OK.
  2. Use the Add New Hardware Wizard to redetect the port. To do so, follow these steps:
    1. In Control Panel, double-click the Add New Hardware icon.
    2. Click Next, click Yes (Recommended), and then click Next.
    3. Follow the instructions on the screen.
    Note that the Add New Hardware Wizard may detect only ECP ports (not standard LPT ports). If this occurs, follow these steps:
    1. Install the ECP port.
    2. In Control Panel, double-click System.
    3. On the Device Manager tab, double-click Ports (COM & LPT), and then double-click the ECP port.
    4. On the Driver tab, click Change Driver.
    5. Click the Show All Devices option.
    6. In the Manufacturers box, click Standard Port Types. In the Models box, click Printer Port, and then click OK.
    7. Click OK.
  3. When the Add New Hardware Wizard is finished, copy the Lpt.vxd file from the Drivers\Printer\LPT folder on the Windows 95 compact disc to the Windows\System folder. NOTE: The Lpt.vxd file is also available from the Printer Driver section on the Microsoft Windows World Wide Web page at:
