Mac OS 8.6: Computer Stops Responding After Printing to an LPR Printer

This will happen on a Macintosh computer with Mac OS 8.6 and LaserWriter 8, version 8.6.5 when either of these conditions exist:

• The computer's TCP/IP control panel settings are not configured. (If the TCP/IP control panel had never been configured, or if the TCP/IP Preference file was deleted.)
• TCP/IP is inactive.

Your computer is not responding because each time it restarts all queued print jobs are sent to the printer, but they cannot be printed because the TCP/IP control panel is not configured, or TCP/IP is inactive. Follow these steps to configure your TCP/IP control panel:

Delete the print jobs

1. Restart your computer by pressing the Shift key during system startup time to turn off system extensions, including the Desktop Printer extensions.

2. Find and select the icon of the Desktop Printer you are using. (It will have an X over it.)

3. Double-click to open the Desktop Printer.

4. Delete or remove the print job(s).

5. Restart your computer.

Configure your TCP/IP control panel settings

1. Open the TCP/IP control panel.

2. Enter your computer's TCP/IP settings. Consult your network administrator if you do not have them. For assistance, click the Help button, or choose Show Balloons from the Help menu.

3. Close the TCP/IP control panel and save changes.

Activate the TCP/IP protocol

1. Open the TCP/IP control panel.

2. Choose User Mode from the Edit menu. The User Mode window appears.

3. Click the Advanced button.

4. Click OK.

5. Click the Options button in the TCP/IP configuration window.

6. Click the Active button in the TCP/IP Options window.

7. Click OK.

8. Close the TCP/IP configuration window.

9. Save changes.

Now that the TCP/IP control panel is configured, or activated, your computer will print to the LPR printer.
