No problem. LPD is just a way to get some data over to the printer.
You can do that using a native LPD printer symbiont, or anything else
(like DCPS) can use that protocol. The difference is mainly that port
515 is used for LPD and 9100 for "raw" printout. Maybe some different
handshaking going on...

Now, our printouts works just fine on a similar Zerox Phaser 3250,
so it might be some small differences in how the printer firmware
detects different printer languages. In this case (a slightly cheaper
printer than the Phaser), it doesn't detect the PS code and simply
prints out 40 pages of PS code instead...

We might set this printer to not use DCPS and print the raw text
instead. It is just plain ASCII with no control characters (apart
from the <CR><LF> for each line) pr other printer commands...

But thanks anyway!

Jan-Erik.
