Raw text to IP Printer

We were printing to a serial laser printer with all the HP codes to generate a form (i.e. lines, boxes, etc.) We are switching to an IP printer and we can no longer print to the device (i.e. cp text /dev/tty11). It looks like we have to use the lp spooler now. When we do this the codes are ignored as the line is too long. Is there away to send raw text to an IP printer that is using the Jet Direct card to setup the queues? I saw an stty option on the lp command, can that be used to put it in raw mode?

Thanx for your help
