Performa 475: Using Serial Printers With Fax Modem (6/94)

I am using a Performa 475 running System 7.1P6 and I am having many problems printing to a LaserWriter Select 310:

- The computer doesn't retain the Setup information for the printer.
- Intermittantly an error code of -1401 appears when trying to print.
- Sometimes, the "Setup" button in the Chooser can't be accessed.

When I removed the fax/modem software, all of the problems disappeared.

Some fax/modem software will typically "capture" a port, and place it
"in-use". If you are trying to print to a serial printer connected to that same port, you may encounter errors such as those listed above.

Other than disabling the software, you might try to configure the fax/modem
software (or the printer) to use the other port.
