Description: Returns or configures the amount of memory, in bytes, dedicated to I/O print job data buffering. Attempting to set to an unsupported value causes the device to use the closest supported value. Each device POS should document the list of supported values. Additional information: When IO-BUFFERING is eOff, reading this object will return a value of zero. Attempting to set this object when IO-BUFFERING is eOff will cause a status of to be returned. When IO-BUFFERING is eAuto, the printer determines the value of this object. Attempting to set this object when IO-BUFFERING is eAuto will cause a status of to be returned. Reading this object when IO-BUFFERING is eAuto will return the value that is currently being used by the printer; the value is based on the printer configuration and is as follows: PCL-only: If 4M installed, 10240; if >4M installed, 102400 for each 1M over 4M. PCL & PS: If <12M installed, eAuto cannot be set; if 12M installed, 10240; if >12M installed, 102400 for each 1M over 12M. PCL, PS & Duplex Unit: If <23M installed, eAuto cannot be set; if 23M installed, 10240; if >23M installed, 102400 for each 1M over 23M. When IO-BUFFERING is eOn, the range of values supported by this object varies depending on the printer's configuration. The minimum value is 10240; the maximum value is the current value of this object plus the value of MAXIMUM-IO-BUFFERING-MEMORY. Supported values are multiples of 10240 for values less or equal to 97280 and multiples of 102400 for values greater than 97280. Setting to an unsupported value causes the printer to substitute the nearest supported value and to return status.
