[Samba] Can't print properly through server, only direct client->printer

[Doug VanLeuven]

I read ^[0-9]* *VM\? as
match 0 or more occurances of a digit at the beginning of a line
match zero or more occurances of a space
match a V
optionally match one M (shell interpretive issues with backslash and ?)
3V)_ and 9VL@ both meet that criteria.

rather
^[0-9]+ +VM\\[?]
if you're looking for
0 VM\?

I find it helpful to eliminate shell issues by making special characters 
in a class
       A regular expression may be followed by one of several repetition 
oper-
       ators:
       ?      The preceding item is optional and matched at most once.
       *      The preceding item will be matched zero or more times.
       +      The preceding item will be matched one or more times.
