Hi Paul,

It looks like you are getting blasted. Any chance you are still sending

I know everyone seems to be asking the same question. Me too. Can you
send me the code.
Thanks

Can you also forward this code example to me as well, it seems to be
very popular, and would save me countless hours of trial and error.
Thank you,

Here is some sample c# code to print directly to a ZPL or EPL printer

Hi Guyz,

after 2 days of finding a solution with out risking the vunerability of
the server. I found the ultimate solution, for me that is, What i did is
to create an aspx page where when the user will click on the button it
will download the EPL file. From there i created a .bat file that
commands it to print the opened file. I set the .bat file as the default
program to open any .epl file.

It works perfectly, whether your in an intranet or internet. I works
because the printer is now in the client side.

Hi Paul,

Could you please provide me with the sample code. Also if the zebra
printers are wireless is there a way to identify the nearest active
zebra printer when printing? Thanks in Advance!
