OPMSG Command The OPMSG command prompts the printer to display the specified message and go offline. Use this command to display a message and halt printing until the operator presses the On Line, Continue, or Reset key. Syntax: @PJL OPMSG DISPLAY = "message" [] Parameters: Parameter Functional Range Default DISPLAY = "message" Roman-8 characters 33 N/A and 35 - 255, , DISPLAY = "message" - The variable message can be any combination of printable characters (except quotation marks, character 34) and spaces or horizontal tab characters, with a limit of 1 line of 16 characters (see "Comments" below). The message variable is a string and must be enclosed in quotation marks as shown in the command syntax. Comments: On some HP printers, the first two display characters blink. To avoid blinking, begin the message with two blank spaces. Some HP LaserJet printers may have a different limit for the number of display lines and number of display characters. To request the display limitations, use the INFO CONFIG command. The printer returns DISPLAY LINES=value and DISPLAY CHARACTER SIZE=value as part of the response message. For example, the HP LaserJet 4 and 4M printers return DISPLAY LINES=1, DISPLAY CHARACTER SIZE=16, indicating that the displayed message is limited to 1 line of 16 characters. Note For HP LaserJet 4PJ, 4V, 4MV, 5Si, 5SiMx, 5Si Mopier printers, if the LANG variable is set to Japanese, the message is displayed in the JIS X0201-76 character set. 8-4 Device Attendance Commands
