I have a printing device with a serial interface.
It is connected to a serial port of a print server, that is connected to the
network.
To day I am printing from a UNIX box, but I am moving the system to a
Windows platform.

The application is printing to a LPT-port (e.g. LPT9).
LPT9 is redirected to \\server\sharename using NET USE LPT9:
\\server\sharename

My problem is: What I am sending into LPT9 is NOT what the printing device
is receives.

My best guess is that the printerdriver on \\server\sharename is trying to
interpreter the data received from LPT9.

Here is a little example:

The \\server\sharename is installed with a driver: Generic/Text only

LPT9 receives:
01 50 02 31 41 4B 53 45 .P.1AKSE
4C 42 03 0D 01 56 02 30 LB...V.0

56 02 30 32 33 33 33 33 V.023333

30 34 31 31 31 31 03 0D 041111..

The printing device receives:
0D 0A 0D 0A 20 50 31 41 .... P1A
4B 53 45 4C 42 0D 0A 20 KSELB..

How can I define a printer, that is totally transparent?

Ebbe

The 0A 0D pairs are line feed / carriage return codes. In properties on the
Generic/Text only driver / Advanced tab / Print Processor button, is default
data are you set to type set to RAW? If not, that might be the problem.
What print server device are you using?

If printing to a shared printer using the Windows NT LPD service,
control codes are sometimes added to the data stream - it doesn't
matter which driver is being used. This can be disabled using the
SimulatePassThrough regkey:

Ooops - if printing via "net use" you are probably not using the
LPDSVC... /-:
What is the source platform, and does it support printing to a file
instead of a device to determine if the codes are being added/modified
by the local platform or the printer server?
If the printer server is a small network box, it might support
NetBEUI - these can be addressed directly from Windows clients.

Hey!

Unfortunately I discovered, that the problem was what I sent into the
LPT-port :-(
I had'nt control over the application.
After more tests I discovered an error in the application adn then ---- It
all worked.
