Here in the Stanford Knowledge Systems Laboratory we have 7 Imagen laser printers which speak IP/TCP. I don't believe we've had any problems protocolwise. We speak to the printers using IP/TCP from a Decsystem20, some Berkeley unix 4.2 vaxen, and from Xerox, Symbolics, and TI lisp machines. You can try a connection "by hand" by telnetting to port 35 on the printer and typing in a document by hand. The dialog below takes place on our 20. No text comes back from the printer, but the fact that the TCP connection opened, accepted data, and closed gracefully indicates that the transfer worked. To debug your connection, you might want to type (on the printer console) "SC" (for "Set Communications-debugging") and then type "IC" (for "Info Communications") to get into the debugging executive. If your printer is on the arpa internet, I can try printing on it from here if you wish. Just tell me the IP address. Good luck, --Christopher @tn sumex-cdp0.stanford.edu 35 Trying...
