Application can't print to LPT1
Posted on 1998-06-14
An application that runs under dos, made with CA-Clipper 5.3b cannot print to local printer in Novell 3.11 or 3.12. Returns error code "0" inerpreted as "invalid file handle".
The strange thing is that this happens in one lan and does not happen in others (about 10) of the same type.
For people that are familiar to clipper the command is:
"Copy &filename to &OutputDev", where OutputDev="LPT1".
The syntax "!copy &FileName &OutputDev", that calls the OS shell to execute the command works fine.
What could be the cause of such a strange behaviour? I have never worked with Novell 3.1x, only with 2.2 and 4.x where I never had such a problem and I never had it with other clients of mine that installed my application on 3.1x.
