1. Do you have netcat or if binary is available? .... "netcat: Command not found." and no I do not know if any binary's are available.
2. Could stop print service and manually edit? .... I kind of was looking for an automated process to determine what would print and what would get "dumped"
3. Unix release and binary compatible? .... Compaq Tru64 UNIX V5.1B (Rev. 2650) and I believe it is binary compatible (it has samba) but that may not be 100% accurate

1. There is no GUI anywhere that I can find. It does not even seem to have xwindows. I am basically 100% CLI.
2. Yes, lpadmin is available to me.
3. Setup class for the printer....??? sorry, way over my head... please explain in more detail if you want me to follow
4. Modify filter file... Yeah, that was kind of what I was hoping to do. Copy and modify current filter file with something that would block print jobs that did not start with Manual.
5. Absolutely no worries about being a little rusty.... I have no experience at all and this is soooo ancient I had many problems finding any information at all on it. Any help you can offer or light you can shed is more than greatly appreciated.

FYI: This machine is currently being used in a production environment so any changes made need to be small and minor with little impact to the system.

how to configure the lp system to filter files passed to it

I registered a printer hp123 on Sun Solaris Server. I think my printer is expecting a carriage return and linefeed combination at the end of each line (DOS standard), but unix files only have linefeeds at the end of each line. How can I configure the lp system to filter files passed to it?...

lpsched

lpsched(1M)                                               System Administration Commands                                               lpsched(1M)

NAME

       lpsched - start the LP print service

SYNOPSIS

       lpsched [-f num_filters] [-n num_notifiers] [-p fd_limit] [-r reserved_fds]

DESCRIPTION

       The  lpsched command  starts or restarts the  LP print service.

       The  lpshut command stops the  LP print service.  Printers that are restarted using lpsched reprint (in their entirety) print requests that
       were stopped by  lpshut. See  lpshut(1M).

       It is recommended that you start  and stop the LP print service using svcadm(1M).  See NOTES.

OPTIONS

       The following options are supported:

       -f num_filters          Specifies the number of concurrent slow filters that may be run on a print server. A default value of 1 is used  if
                               none  is  specified. Depending on server configuration, a value of  1 may cause printers to remain idle while there
                               are jobs queued to them.

       -n num_notifiers        Specifies the number of concurrent notification processes that can run on a print server. A default value of  1  is
                               used when none is specified.

       -p fd_limit             Specifies  the file descriptor resource limit for the  lpsched process. A default value of  4096 is used if none is
                               specified. On extremely large and active print servers, it may be necessary to increase this value.

       -r reserved_fds         Specifies the number of file descriptors that the scheduler reserves for internal communications under heavy  load.
                               A  default  value  of   2  is  used  when none is specified. It should not be necessary to modify this value unless
                               instructed to do so when troubleshooting problems under high load.

EXIT STATUS

       The following exit values are returned:

       0               Successful completion.

       non-zero        An error occurred.

FILES

       /var/spool/lp/*         LP print queue.

NOTES

       The lpsched service is managed by the service management facility, smf(5), under the service identifier:

       svc:/application/print/server

       Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed  using  svcadm(1M).  The  ser-
       vice's status can be queried using the svcs(1) command.
