I have a user with an ancient perl application that prints directly to an equally ancient dot matrix printer. Under Windows 7 and 10 I was able to use "NET USE LPT1: \\LOCALHOST\DOTMATRIX" to get it to print. Now the user has a new PC with Windows 11 and never gets paper output. I found that it does create a file "lpt1" with the contents needed. The code to actually print: open(F, '>LPT1') or die ("Can't open printer: $!"); print F $s; close F; What is missing that it doesn't seem to use the device mapping under Windows 11? Thanks.
