Our PSERVER would start sending to the printer buffer, about a page would print emptying out the buffer, then the printer would not tell PSERVER to continue sending to the 3816 print buffer. It turned out to be a handshaking problem. We were using the latest print server software. SOLUTION: The pin settings were changed to the following: 1. pc pin 2 goes to pin 3 on the printer. pc pin 3 goes to pin 2 on the printer. pc pin 4 goes to pin 5 on the printer. pc pin 5 goes to pin 20 on the printer. pc pin 6 goes to pin 4 on the printer. pc pin 7 goes to pin 7 to establish grounding. pc pin 8 is jumpered on pin 4 on printer. 2. Also make sure Dip switch 6 is on. Switch 6 asserts DTR (Data Terminal Ready). All others should be off except for 1-3 which adjust your speed. 3. XOFF/XON was set to ON in pconsole. These settings got RPRINTER to work correctly. (X) This information was verified verbally. (X) This information was verified by the vendor.
