Variable BITSPERPIXEL CLEARABLEWARNINGS CONTEXTSWITCH COPIES COURIER General PJL Environment Variables Description Sample Value Range For PCL 6 only, this variable controls the 2, 1 number of bits per pixel used when printing grayscale or color images. The valid values are dependent on the current setting of RESOLU- TION. If RESOLUTION is 300 or 1200, the only valid BITSPERPIXEL value is 1. If RESOLUTION is 600, the only valid BITSPER- PIXEL values are 1 and 2. For FastRes 1200 printing, first set the RESOLUTION to 600 and then set BITSPERPIXEL to 2. For ProRes 1200, first set the RESOLUTION to 1200 and then set BITSPERPIXEL to 1. Returns the configuration for displaying clearable warnings (non-fatal error messages cleared by pressing the Continue key.) If the value is set to JOB, then clearable warnings generated by a job are displayed only until the start of the next job. If the value is ON, then clearable warnings are displayed until the user presses the Continue key. JOB, ON Enables/disables the use of implicit personality switching. If a job is sent without an ENTER LANGUAGE command, the printer looks for context clues to determine which personality takes effect. When the personality is changed, memory is reconfigured and all downloaded fonts, PCL macros, and PostScript dictionaries are lost (however, no I/O data is lost). ON, OFF Number of uncollated copies for each page of the job. 1 to 999 Sets the version of the Courier font. REGULAR, DARK 6-12 Environment Commands
