you don't have to adjust kernel parameters. check the chuser command or /etc/security/limits file. you can set a system wide default or at the per-user level.
ncargs is how much memory is used
arg_max is the length of the parameter list + environment
Do you really need to send 500k of data as an argument?

lpusers(1M) System Administration Commands lpusers(1M)
NAME
lpusers - set printing queue priorities
SYNOPSIS
lpusers -d priority-level
lpusers -q priority-level -u login-ID-list
lpusers -u login-ID-list
lpusers -q priority-level
lpusers -l
DESCRIPTION
The lpusers command sets limits to the queue priority level that can be assigned to jobs submitted by users of the LP print service.
The first form of the command (with -d) sets the system-wide priority default to priority-level, where priority-level is a value of 0 to
39, with 0 being the highest priority. If a user does not specify a priority level with a print request (see lp(1)), the default priority
level is used. Initially, the default priority level is 20.
The second form of the command (with -q and -u) sets the default highest priority-level (0-39) that the users in login-ID-list can request
when submitting a print request. The login-ID-list argument may include any or all of the following constructs:
login-ID A user on any system
system_name!login-ID A user on the system system_name
system_name!all All users on system system_name
all!login-ID A user on all systems
all All users on all systems
Users that have been given a limit cannot submit a print request with a higher priority level than the one assigned, nor can they change a
request that has already been submitted to have a higher priority. Any print requests submitted with priority levels higher than allowed
will be given the highest priority allowed.
The third form of the command (with -u) removes any explicit priority level for the specified users.
The fourth form of the command (with -q) sets the default highest priority level for all users not explicitly covered by the use of the
second form of this command.
The last form of the command (with -l) lists the default priority level and the priority limits assigned to users.
OPTIONS
The following options are supported:
-d priority-level
Set the system-wide priority default to priority-level.
-l
List the default priority level and the priority limits assigned to users.
-q priority-level
Set the default highest priority level for all users not explicitly covered.
-q priority-level -u login-ID-list
Set the default highest priority-level that the users in login-ID-list can request when submitting a print request.
-u login-ID-list
Remove any explicit priority level for the specified users.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
non-zero An error occurred.
