I have asked this question before, but our posting of news got  hoosed
so i am asking it again......

----------

I have a Laserjet III, and i wanted to write a  programm  that  prints
stuff  to  it from intuition. (Yes i know that they are out there, but
none of it does what i want it to do)

I  want  to  controll the printer by bypassing the printer.device from
amiga and directly go to PRT:

I have opened PRT with both Open and fopen. Sent some escape sequences
just like the manual says is takes. And see it do _nothing_

Example a string like this. (THis is only an example)

<ESC>[5j

Will result on the prinout as:

5j

It eats up my ESCAPE character and my [  character.  while  it  should
interped as something changing from landscap  to  portait.  changing
point size etc etc.

Whatever escape sequence i sent the prnter it just prints it out minus
the escape character. I have tried by sending the real escape Sequence character its octal and
decimal value, but to no avail.

Is there something i am doing basicly wrong. 

The ROM manual staes that when you open PRT: directly all is sent to the printer RAW.

Does anybody have any idea that they like to share.????

Thanx,

Hank Janssen,
