Conventional Printer to IPP

6 posts in this topic

#1 ·  Posted (edited)

A little background might be needed here. We have a relatively large operation here, 2k users, 1k pcs, 200 servers, and around 500 printers. Now, this is an abnormally high amount of printers given the amount of users, but many of these printers are just label printers, and, therefore specific to a task. A side effect of the amount an variety of the printers is a high amount of drivers and issues with those drivers. We are stiting at 206 different drivers for those printers. Long story short - our Windows printservers are crashing on a daily/weekly basis, and Microsoft support tells us to split up our printers by type into different servers. This seems like a bad idea given our users who are very used to a single point of use for the printers. So... in comes linux with Cups. Cups is cool in that it's a stateless protocol, etc. But how do we convert from old to new without having to touch everyone's PC? Well, I'm just starting down the line here, and so this is my first script. It's useable, and can convert from \\printserver\PRINTER to an IPP based PRINTER. So far this is working well. I aim to mysql-ize this because there is much to do with the linux side of this. However, I thought I'd share just in case anyone else needs something like this. Many of you will recognize your code :) Many of you will recognize code from the help pages. I thank all of you who unknowingly helped!

Cool, I am sure this will be beneficial to many. At my place of work we only have an ip printer at different areas and each user uses the one closest to their cube. Please keep us updated with your progress..

heh, I don't think very many folks will find this useful really, but it's handy if you need something like this. Mostly this would be useful for ppl who have Samba fileservers/printservers and quite a few printers - colleges, hospitals, etc. Normal users won't really care.

Anyway, the script is now functional. It's smart enough not to recreate printers (eg no Copy1, Copy2, etc printers), does a few safety checks, etc. Still, use at your own risk.

If someone has already done this and I'm just re-inventing this wheel, I'd like to know, because I'm sure the way I code isn't so hot (I just do what it take to get the job done). Anyway, if you do happen to use it, and it errors out, it'd be nice to know I've only got access to XP and win2k3 machines, so if it's a vista thing, I've no idea whats wrong, and really don't wish to try to fix it.

Oh, I've posted the lastest version of the code too...

have a good one!

Hi,

Cool script. But I found you invoke those vbscript from system a lot. Why not use COM interface within AutoIT?

I'm trying to write such script recently.

If I could finish it, I'll post it here.

:-)

Okay, so, after several other projects, I've come back to AutoIT stuff and working with this rather minor project.

Li Hang:

Thanks for the compliment, however, I don't know how to use the COM interface. I'll take a look at it. To tell you the truth, I'm a unix guy working in the windows world, so a bit of this stuff is tough for me to get a handle on. WIll take a look though, thanks for the tip!

So... onward and upward. Latest version of AutoIT downloaded, time to see how many better ways there are to accomplish this task :oops:
