copy text file to com printer

[MindBender77]

Hello All,
I've been fussing with this for the last few days. I'm attempting to copy a text file to a zebra printer that is wired to com 12. I've been using Window's command prompt to test this, however, when I sent the file to the com port nothing happens. Am i missing something? Here is the simple command I'm using.

C:> copy test.txt com12

Any suggestions will help at this point.

Hello,

You should instead type something like:

C:> copy test.txt > com0

In your code, you missed redirection operator '>'. You might be amazed why I redirected the contents of test.txt to com0 and so read on.

Are you sure that your printer is connected to com12? IMO, there are only 10 com ports (ranging from com0 to com9) to which data can actually be redirected in windows OSes. I don't think you can redirect data to com12 because windows thinks that you are redirecting to a file named com12 and not device 'com12'. You should either connect your printer to a com port between com0 to com9 or you should try some different approach. But then, I may be wrong too as I am not sure.

Hope this helps...

Agreed, however, this particular machine uses a digi-board increasing the number of coms. Also, we have an INI file stating which com the printer is using. I'll give your suggest a go and post back the results.

Thank you for your help,

I finally got this problem solved. Here is the code so it may assist others.

C:>copy file.ext \\.\com12 /b
