Mysterious numbered file appears in Application Support Folder.

Question

I had posted this question a few days ago and now I found the original post is locked for some reason. I would like to continue a related question and so I am posting a new, but similar, question:
I was looking through my OSX installation and I found this mysterious file placed in my Application Support Folder in my library:
username/library/application support/7103555
It is named "7103555" and it is a Unix Executable File (according to "Get Info") I was worried it could be a virus - but now I doubt it (but you can never be too careful). Should I delete it?
It looks like this when you open it:
cd /System/Library/SystemConfiguration/PrinterNotifications.bundle/Contents/MacOS
# SUDO is causing entries in the console log making me believe
# that it's not getting run correctly. I am removing SUDO from the
# command lines.
#sudo ./makequeues -u
#sudo ./makequeues -r
./makequeues -u;./makequeues -r&
exit 0
Wayne indicated it is only a shell script call to the PrinterNotification.bundle. Wayne, will I be OK to just leave it or should I delete it?
I am left feeling "somewhat" assured that this mysterious file is OK. I am still tempted to delete it - but I am not sure if I should. What bothers me about it is that (as I mentioned originally), when I select the file and choose "Get Info" it indicates it is a "Unix Executable file". That sounds like a recipe for a potential virus to me. And I know there aren't many viruses targeting macs however that fact never reassures me.
Also, all the other files that end up in this users "application support" folder are clearly identified by their creators. For example, when I installed Mozilla Firefox, its support files are created at this location and they are clearly labelled "firefox". On the other hand, this mysterious file is not labeled and is only given a number as so:
username/library/application support/7103555
Should I leave it or delete it?
PS When I get a chance one day, I will install ClamXAV and run that as well. I am sure I don't have any viruses but it wouldn't hurt to give it a try - especially considering its free (actually its by donation).

Thanks Mulder, Wayne and Ewen for your replies to the original post and for your help - and for the interesting, informative debate too

Answer 1

Thanks etresoft
Yes, I tried printing again and the file remains. After printing and during printing no other files are added to this location (my user "Application Support" folder). Strange. Its only a 4 K file and when I open it in text edit it reads what I mentioned above (SUDO is causing entries in the console log followed my a few other lines of text about makequeues).
The printer is an HP cp1160. Maybe it is not a well-designed print driver. It works but I think its strange that this file ends up in Application support, without a name, doesn't disappear and is a "Unix executable file". When I do a "Get info" on the file it says it is a "Unix executable file".
Until I hear from anyone else, I am just going to leave it alone. (I also will not attempt to "save it" after I open it in test edit - I'll just let it be). In the future I will watch this file and later I will run a virus scan on it with ClamXAV.
I am gradually becoming assured that it is probably a safe file to leave alone. (I was so tempted to delete it).
Actually I might delete it as an experiment later and also delete my HP cp1160 printer driver (if I can find it) then re-install the HPcp1160 printer driver again to see if this file comes back. I might try this. I'll have to think about that.
Thanks again etresoft.
