Troubleshooting AppleTalk

E.1 Troubleshooting Tips

The following are troubleshooting tips for AppleTalk.

E.1.1 Reset Time

The default for reset time may have to be changed. The reset time is the amount of time FastPort waits before sending the next print job to a printer. Since reset times for the printers vary greatly, FastPort uses values specified by the variables Wait Time Before Reset and Wait Time After Reset to delay sending print jobs before and after a reset sequence. These are set via the SetUp Defaults file (see “Using Setup Defaults File” on page 6-4).

E.1.2 Configuration to Use the ACK Signal

FastPort relies on the ACK signal from the printer. Sometimes printers require the use of more signals (for example, Busy) to send correctly on the interface. If the unit is having parallel flow control problems, modify the flow control method (see “Using Setup Defaults File” on page 6-4).

E.1.3 Situation 1: Printing Over Ethertalk Using Driver 7.x

The serial port fails when the user tries to print over EtherTalk using driver 7.x to LaserWriter printers. For bi-directional printing support across the serial interface (for LaserWriter II and II NT printers), use the following procedure. The printer needs to be initialized with correct data and parity values. Do this by either making a telnet connection into the serial port of FastPort or connecting a terminal to the printer’s serial port.

1.Turn the LaserWriter off and set the front panel switches D1 and D2 down. This sets the Laser Writer in PS Batch Mode with these values for RS-232 set for 9600 baud, RS-422 set for 9600 baud with port values of 7 data bits, no parity check, 1 stop bit, and Xon/Xoff.

2.Turn on the LaserWriter. It prints a test page with current settings.
