udev rule for usb printer

[Bob Barry <bobb@absamail.co.za>]

I have a Lexmark Z52 usb printer.  To get it going I put the following into /etc/udev/udev.rules:
   # USB Lexmark Z52 printer to be called lp_Z52
   BUS="usb", SYSFS_product="Lexmark Z52", NAME="lp_Z52", SYMLINK="usblp0"
But hotplug/udev ignored it and started:
   crw-rw----    1 root     lp       180,   0 2004-01-08 17:46 /dev/lp0
with no symlink.

I got the "product" label from:
   asterix:udev> cd /sys
   asterix:sys> find . -type f | xargs grep Z52 2>/dev/null
   ./devices/pci0000:00/0000:00:02.0/usb1/1-1/product:Lexmark Z52

To be very sure of what was in the string:
   asterix:sys> s=$(find . -type f | xargs grep Z52 2>/dev/null); s=${s}"XX"; echo $s
   ./devices/pci0000:00/0000:00:02.0/usb1/1-1/product:Lexmark Z52XX
   asterix:sys> echo ${s##*:}                                                      
   Lexmark Z52XX
   asterix:sys> echo ${s##*:} | od -t x1
   0000000 4c 65 78 6d 61 72 6b 20 5a 35 32 58 58 0a
   0000016
   asterix:sys> 

Should my rule with SYSFS_product have worked?
Is my syntax wrong?
Where am I misunderstanding?
Newbies like me could use heaps more rule examples.

TIA,

Bob Barry
