IMHO the first order of business is to get the device working
in windows. The test of printing a file from notepad is a good
way to isolate the "delphi" problems from the "windows printing"
problems.
>From the sound of it I'd guess you are having "flow control" problems.
There could be lots of reasons:
1. a faulty cable - so that data restraint signals from the printer
aren't being seen.
2. the printer may be configured to do "soft" flow control but the
print driver is expecting hardware flow control. Or vice versa.
3. the print driver settings for flow control may be "none" or
disagree with the printer configuration. (The driver may not
give you a way to set this - it may depend on the "port" configuration).
4. you are using software flow control - and some disagreement in
"parity" settings between the system and the printer device is
causing the "XON/XOFF" characters sent by one side to be unrecognised
by the other side.
(I'm no expert - there are probably other reasons).
Once you get it well-behaved printing from notepad I'd expect
your delphi printing problem to disappear.

Subject: [DUG]: Generic Printing
Question -
Any tricks to printing to a generic / text only printer ?
I'm having all sorts of problems such as not printing all text sent and
extra line feeds :-(
I am using AssignPrn etc
Problems seem to be apparent from windows as well ie won't print all of a
simple text file from Notepad.
TIA
