Configuration Parameter Values Parameter values are settings that the printer recognizes to do the following: Format the printed page Set printing and performance options Set character sets for different languages Modify the alarm volume or disable the alarm. The printer can use the parameter values set by the factory, or you can change them. The new values you set from the operator panel become the new parameter values. Important Changes to these values will not be saved when you turn the printer Off (O) unless you choose to save them in a Custom Default Set. In other words, all configuration changes are online-only changes until they are saved using the Save Current Values parameter in the Configuration Menu under Configuration Storage. For detailed information on saving configuration changes, see "Storing Configuration Parameters" in IBM 4230 Printer Models 101, 1S2, 201, 2S2, 4S3, and 5S3 Operator Panel Instructions. Some of the values you can change from the Configuration Menu on the operator panel are: Characters per inch (CPI) Lines per inch (LPI) Maximum print position (MPP) Maximum page length (MPL) Print language Display language Printer address (Models 101, 1S2, and 4S3) System interface (Models 4S3 and 5S3 when parallel or serial is the active interface) Print quality Alarm setting. 3-16 User's Guide
