I'm attempting to make a variety of systems (W94, NT4 and W2000) print consistently to a rather pathetic bar code printer, which may or may not be the local (LPT1) printer.
Essentially I've resorting to fiddling with Expr, Tag and Tag1 in the .lbx file, leaving it as read-only and compiling the label into the executable.

My code switches the printer using
SET PRINTER TO NAME Label_printer_name
might include a UNC path, but that doesn't seem to be too much of a problem.
Then it simply prints the label and switches the printer back to the default.
I don't want the user having to spend time selecting printers.

However on NT4 for example the thing always prints to LPT1 which is where the label printer is located on my development machine, even though the named printer exists on the network.
If I remove the LPT1: reference from the Expr field and delete Tag and Tag1 contents from label.lbx then it seems to work. But I don't know why or if that's what I should be doing. In other words I'm voodoo programming :-)
Can anyone say how this ought to be done?
