Hi there


when I run rsh printername "date > /dev/ttyS2" I get date: write error: I/O error

If users try to print, their jobs just get queued.
Anyone know what the cause of this is?

This is an EPSON serial printer.

Your command is saying "send the command 'date' to printername and redirect it to printername's /dev/ttyS2" Presumably what you really want to do is print 'date' on the printer attached to /dev/ttyS2 on your local host. If so it should just be "date > /dev/ttyS2" leaving out the rsh and printername.

Restated: The printer itself doesn't have an operating system and doesn't have devices like /dev/ttyS2 but your command is attempting to go to the printer's operating system and redirect from there to a device so is wrong on two counts.
