There are two modes for sending the Printer Select Code. In Printer Select Mode 2 (printer selection anytime while printing), Print Master looks for the Printer Select Code any time. If no Printer Select Code is received, the data will be routed to the default printer.
In Printer Select Mode 1 (printer selection at beginning of printing), Print Master looks for the start of the Printer Select Code in the first 16 characters received. If the first characters of the Printer Select Code are not received within 16 characters, the data will be routed to the previously designated printer. If the first characters of the Printer Select Code are received within 16 characters and a valid printer select sequence is then received, the new printer port number is stored and data will be routed to that printer.
NOTE: In Print Select Mode 1, the Model 706A and 708A will recognize the printer select code only if the very first characters of the print job contain the printer select code.
The printer select sequence may be sent manually from a computer keyboard, by inserting it into a file, or by using BayTech's support software. Please see Section 6.2.8 for a description of various methods used to select specific printer ports.
In multiple printer applications, if no specific printer is desired (i.e. if the print job may be sent to any printer), you may send the printer contention sequence which consists of the Printer Select Code (factory set is $PRINTER) followed by 0 (zero). Print data received by Print Master's buffer is passed to the next available printer on a
The printer contention sequence is trapped if valid and not passed to the printer. The printer contention sequence needs to be sent only once. It is then stored in
