Hello everyone,

I need to backup the files when printing from graphics window, but how
should I do? Normally if printing from the command window, I may check and
backup it, but from graphics, I have no any idea to do.

Have a good day!

Are you confused or am I? I backup my files every marningat about 1 AM when
I am normally asleep and my monitor is turned _off_ so it does not really
matter if I am running a "graphics window" or not, since I am at that time
running neither a "graphics window" nor a virtual terminal.

What does a display have to do with running backups (that I normally run as
just a routine _cron_ job)?

It sounds like he wants to take storable snapshots, as well as or instead of
actually printing.

Well, maybe I should describe my option aim clearly. Normally persons print
something freely and have no more record or log to check, it's dangerous to
us. Since someone print out our technology drawing and make it open, so I
wanna find a way to keep the print record and check the printing data when
need. If printing from command, it's easy to backup the printing data and
record the operation at the same time. But if he print from the software
window, normally there's one menu to print directly, I have no way to keep
the tail. Is there any way to keep the printing data's snapshot? either
other ways to do?

Maybe you'll tell me to control the files' permission, but sometimes it's
difficult to distinguish them. Some files need to be refered and have to
keep readable to staff inside, but you mayn't ensure the printing copy
diffusing to outside. That's my intention to ensure the control, at least I
may have a way to find the leak hole.

Have a pleasure weekend!

On *nux, at least with the older print systems I am used to - I am pre
CUPS or whatever it is called - every print job does finally go to a
script somewhere that is responsible for various bits of processing -
even if its just throwing a control character out to cause the printer
to linefeed at the end of the job, and these are not hard to alter to
log who printed what, or even to load up a copy of all the print jobs
somewhere else.

You need to identify the chain of scripts that are involved when
anything gets printed, and find a suitable place to modify and split the
print job to keep copies.

Be warned however, that these are usually VERY large indeed.

The unix print jobs go to a print controller which caches the files into a
directory while they are being printed. That directory is /var/spool/cups,
with files starting with c being control files. On my system, those control
files are not erased. This leaves you with the name of the files printed,
the person, the format, the time, etc. (It is a partly text partly binary
file).
