tunelp
tunelp device [options]
System administration command. Control a line printer's device parameters. Without options, print information about device(s).
Options
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.
Reset port.
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 /100 of 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.
