Make your notification command a real script instead of trying to do it
all in one shot. That'll also give you greater flexibility to include
additional information should you want it. Note that this is untested
but it's very straightforward --

#!/bin/sh

# printer-notify-by-email example script
# $1 = $HOSTADDRESS$
# $2 = $NOTIFICATIONTYPE$
# $3 = $HOSTALIAS$
# $4 = $SERVICEDESC$
# $5 = $SERVICESTATE$
# $6 = $CONTACTEMAIL$
#
# Matching notification command command_line --
#  command_line $USER1$/printer-notify-by-email $HOSTADDRESS$
$NOTIFICATIONTYPE$ "$HOSTALIAS$" "$SERVICEDESC" $SERVICESTATE$
$CONTACTEMAIL$

# Get the printer info
/path/to/snmpwalk -v 1 -c public -Ov $1
HOST-RESOURCES-MIB::hrDeviceDescr.1 >
/usr/local/nagios/libexec/printername

# E-mail it to the contact
/path/to/mail -s "** $2 alert - $3/$4 is $5 **" <
/usr/local/nagios/libexec/printername $6

# Remove the printer info
/bin/rm /usr/local/nagios/libexec/printername
