tunelp device [options]
System administration command. Control a line printer's device parameters. Without options, print information about device(s).
Specify whether or not to abort if the printer encounters an error. By default, do not abort.
Retry device n times if it refuses a character. (Default is 250.) After exhausting n, sleep before retrying.
Use irq for specified parallel port. Ignore -t and -c. If 0, restore noninterrupt-driven (polling) action.
Specify whether to abort if device is not online or is out of paper.
Specify whether to print current IRQ setting.
Display printer's current status.
Specify a delay of time in jiffies to sleep before resending a refused character to the device. A jiffy is defined as either one tick of the system clock or one AC cycle time; it should be approximately
1 /100of a second.
Tell the lp driver whether it can trust the IRQ. Useful only if using with interrupts, to handle IRQ printing efficiently. Requires at least Linux 2.1.131.
Specify a delay of time in jiffies to sleep before resending a strobe signal.
