Macros in notes?

What I would like to do, for my network printers, switches, routers, and some other devices, is add more information to the extended info page. I have been playing around with notes and to get decently readable output, I end up with a bunch of ugly looking HTML which I have been duplicating on every host definition. Trying to include printer make, model, print queue, location, primary users, toner part number etc; routers nearest service center, circuit identifier, etc. Works great, hard to maintain.
So I was/have been trying (unsuccessfully) to use macros in my host definition and on the template put in the more complex HTML that would fill in from the macros
The below configs show what I was attempting. I do not get any configuration warnings, I don't however get the value that I have set in the host, I get the literal output: $_HOSTprnMake$. So I'm thinking (1) Nagios doesn't support what I'm trying to do and I can't use macros in notes or (2) I have a syntax error that I'm not seeing. I'm hoping somebody here can give me some insight into which case it might be - especially for #1 before I really start beating my head against the wall.
define host{
use generic-printer
host_name 11314-AR
alias 11314-AR-4200N
address 192.168.98.31
action_url http://192.168.98.31
hostgroups network-printers
_prnMake HP
_prnModel Laserjet 2300n
_prnMainQueue "\\\\lmfj-print\\11314-AR"
}
define host{
name generic-printer ; The name of this host template
use generic-host ; Inherit default values from the generic-host template
check_period 24x7 ; By default, printers are monitored round the clock
check_interval 5 ; Actively check the printer every 5 minutes
retry_interval 1 ; Schedule host check retries at 1 minute intervals
max_check_attempts 10 ; Check each printer 10 times (max)
check_command check-host-alive ; Default command to check if printers are "alive"
notification_period workhours ; Printers are only used during the workday
notification_interval 30 ; Resend notifications every 30 minutes
notification_options d,r ; Only send notifications for specific host states
contact_groups admins ; Notifications get sent to the admins by default
register 0 ; DONT REGISTER THIS - ITS JUST A TEMPLATE
notes <table border=1 width=100% cellpadding=3 cellspacing=0 bgcolor="#FFFFFF" style="border-collapse: collapse" bordercolor="#000000">\
<tr bgcolor="lightblue"><td align="center">Make</td></tr>\
<tr><td align="center">$_HOSTprnMake$</td></tr>\
</table>
}
Any advice/input is very much appreciated.
