has been forwarded to the Printer Working Group “PMP” mail list,
which deals with printer MIB issues. You may well have responses from other
members, but if I understand your question, it is how to interpret the response
to OID </span><span style='font-size:13.5pt;font-family:"Courier New"'>[.iso.3.6.1.2.1.25.3.5.1.2.1].

object in the host resources MIB (RFC2790.) The object value is “bit
coded” as follows, and your program is interpreting the response in
hexadecimal.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:12.0pt'>But remember that, in the MIB,

style='font-size:12.0pt'>it may be easiest conceptually to covert the value to binary
1000 0000 0000 0100. The value read therefore corresponds to bits 0 and bit 13,
low paper and input tray empty.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:12.0pt'>Hope this helps. Note also
that the current Printer MIB is RFC3805, although some printers still support
only the earlier verson.<o:p></o:p></span></p>
