Q: Because with copy command of DOS it can be sent to only Serial port LPT1
A: You can "share' your own (or any) printer, and map it to LPT1 via NET USE. net use lpt1 \\yourpc\sharename /persistent:yes If you still want to print from MS Word via the command prompt, seems that it doesn't work anymore, I guess you'll have to write a macro that prints the doc, and launch it with the /mmacroname parameter.
