title: Convert several thousands Word doc into single PCL file
body: <p>Our customer has tens of thousands of correspondence letters in Word 2007 format. They need to combine all the letters into a <em>single large PCL file</em>, which is then sent to the print vendor for bulk printing.</p>
  
  <p>From what i understand PCL content is generated by a specific printer driver. So whether interactively or programmatically with VBA from the Document.PrintOut() function, when called to print to file, it passes content to the selected/default printer driver to output the PCL format.</p>
  
  <p>Now, they have an existing .NET 1.1 batch job that generates PDF out from those Word documents. They wish to use the same batch job to combine them into that large PCL file. If a printer driver is involved in the process, how can multiple Word docs be programmatically "printed" to the same file?</p>
