title: How to use the same ZPL code in printers with different dpi
body: <p>Has used the ZebraDesigner2 software to create labels for printing ZPL, with the GC420t printer I am not having problems.</p>
  
  <p>Now I have to generate ZPL code for printing labels using the S4M printers (200 dpi) and ZT230 (300 dpi) the problem is the difference in dpi of the same that makes the impression made by S4M skirt very large cutting important information.
  e.g.</p>
  
  <pre><code>^XA
  ^PW1240
  ^LL1724
  ^FT321,845^A0N,42,40^FH\^FDTeste 1234567890^FS
  ^PQ1,0,1,Y^XZ
  </code></pre>
  
  <p>I've tried using the commands below, however I have not found good examples.</p>
  
  <pre><code>^MU – Set Units of Measurement
  ^JM – Set Dots per Millimeter
  </code></pre>
  
  <p>I need print on both printers the same zpl code, can be at 200 or 300 dpi.</p>
