<TITLE>RE: [Pwg-Announce] Call for Review of langPDF/PS/PCL variants for IANAPrinter MIB (30 April 2010)</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/plain format -->
<P><FONT SIZE=2>> I think we are stuck treating these as languages/language families.<BR>
<BR>
I'd like to suggest change the description for langPCL3, langPCL3GUI, langPCL5e, langPCL5c. Rename "HP Printer Command Language xxx" to "Printer Command Language xxx"<BR>
