The CUPS config page is available on http://localhost:631
provided the CUPS server is actually running. Downloading and installing does not start the program running. Also, the latest CUPS also requires that EPS Ghostscript be downloaded and installed as well, separately. Both are availble as Slack packages from the Extras directory for 8.1. Once installed, you should be able to stop/start it manually by using the following:
Once it is running it should respond to the request on port 631. Proceed to configure as desired. I checked my version and it lists an Epson C60 driver but not C62. Perhaps the C60 will work for you. They also listed an item labeled "Epson new color stylus printer" or something similar. You might try that as well if the other doesn't work out.
I think the C62 is a USB printer. So you should be able to use "dmesg" from the console prompt to determine if the USB printer module was loaded and connected to it.
