Menu Item Parallel Buffer Purpose To configure the size of the parallel input buffer. Note: Changing this menu item automatically resets the printer. Values Disabled Auto* 3K to maximum size allowed Parallel Mode 1 Parallel Mode 2 To control the pull-up resistors on the On parallel port signals. This menu item is useful for personal computers that Off* have open collector outputs on the parallel port signals. To determine whether the parallel port On* data is sampled on the leading or trailing edge of strobe. Off PCL To configure the printer so it On* SmartSwitch automatically switches to PCL emulation when a print job received through the parallel port requires it, regardless of the default printer language. Off PS To configure the printer so it On* SmartSwitch automatically switches to PostScript emulation when a print job received through the parallel port requires it, regardless of the default printer language. Off Protocol To specify the parallel interface protocol. Standard Fastbytes* Disables job buffering. Any jobs already buffered on the disk are printed before normal processing of incoming jobs resumes. Printer automatically calculates the Parallel Buffer size (recommended setting). User specifies the Parallel Buffer size. The maximum size depends on the amount of memory in your printer, the size of the other link buffers, and whether Resource Save is set to On or Off. To maximize the range for the Parallel Buffer size, disable or reduce the size of the serial, and USB buffers. Disables the resistors. Enables the resistors. Samples parallel port data on the leading edge of strobe. Samples parallel port data on the trailing edge of strobe. Printer examines data on the parallel interface and selects PCL emulation if the data indicates that is the required printer language. Printer does not examine the incoming data. The printer uses PostScript emulation to process the job if PS SmartSwitch is On, or uses the default printer language specified in the Setup Menu if PS SmartSwitch is Off. Printer examines data on the parallel interface and selects PostScript emulation if the data indicates that is the required printer language. Printer does not examine the incoming data. The printer uses PCL emulation to process the job if PCL SmartSwitch is On, or uses the default printer language specified in the Setup Menu if PCL SmartSwitch is Off. May resolve some parallel interface problems. Provides compatibility with most existing parallel interface implementations (recommended setting). 54
