Printer supports direct text printing with the 'us-ascii' charset.
Should work perfectly with stp.
John P reports that the serial port is fixed at 230400 baud. He was unable
to get this printer speaking to his Debian PPC Mac using a reasonable late-model
2.2.x kernel. It's unclear if it'll work in other serial applications. Hmm.
See his post in the Epson forum.
