I just got a USB To Parallel cable and the printer still says I haven't selected the Epson driver over and over again. I need to know the exact steps to get it going I'm using OS8.6

Hi John,

I would suggest following to troubleshoot:

TRY SERIAL CONNECTION

1) Check your serial cable.  The recommended cable in the User Guide is
  "Apple System Peripheral-8 cable (Part Number M0197)".

Wiring for a standard Mac Printer cable is at the bottom of this page:
http://www.netbsd.org/docs/Hardware/Misc/serial.html#pinouts

1A) As a really rough check on whether you have a connection, boot up in OS-8 or 9, with the printer connected via the serial port, the printer powered on, Appletalk on, and select "connect via printer port" in the AppleTalk control panel. The printer should start printing random characters. If it doesn't, one might suspect either the cable itself, or the interface hardware at one or both ends of the cable.

1B) If possible substite a cable which is known to be working from another installation. If this is not possible, you can manually check each pair of pins in the cable using an ohmmeter and the wiring diagram from the above link. Inspect the cable visually for broken, bent, missing, or 'pushed in' pins.

1C) Assuming the cable is OK, try to eliminate corroded or dirty connector pins and/or sockets as a possible cause. Visually inspect, seat and re-seat the cables.

2) if you are happy that the cable is good, and given that your USB to Serial adaptor is also not working, suspicion can fall on either a hardware problem at the printer end, or a software problem on the Mac. I think the easiest check of the software would be to download the latest SC600 software from Epson, then restart with the base set of extensions and control panels, using the Extensions Manager control panel, before reinstalling the drivers. Do this on both Macs.

3) If 1) and 2) have failed to produce a result, you'd have to start taking the printer apart and inspecting the circuit boards for possible problems, or else suspect that both your Macs have faulty serial ports.
