I would *NOT* recommend mConsole. They are impossible to work with. There's been an update out for a while now and I can't get anyone there to respond to my inquiries. I have asked my IT person (contracted) to see if he can get a hold of them. I haven't heard a word from either of them (which doesn't surprise me).

We dropped mConsole a few years ago, service being a large part of the issue. We are using CASSIE now, it's very affordable, and so far, no issues as long as upgrades are installed. 

Support, to my knowledge, is very good. We outsource all our IT needs, so no one on staff is directly managing the admin side of things. But I will say that our IT vendor, who works with many libraries in our Cooperative, recommended CASSIE and all their library clients use CASSIE as well.

We use Cybrarian but I think MConsole is a little easier to work with.

Cybrarian. It’s the default time/print management software at libraries in our region. It’s licensed through our cooperative, but I know it’s inexpensive for what it does. We’ve been using it since the late 1990s. We’ve just never felt a need to change vendors.

Cybrarian is configurable and modular, has decent features, including authentication against our patron database. Setting it up properly can be a bit complicated, but documentation is good and so is the support. I have not worked directly with support, my co-op does that, but they have been able to solve any problems I’ve had (few). You don’t have to install the print module, it’s a separate program you can leave off. The time management works very well. We do not use the reservations module either. It can be configured to shut down the computer at the end of the night, though I am using DeepFreeze to manage that.  Cybrarian can lock down the interface, which we take advantage of, in addition to group policy objects on the domain.

We switched to TBS (Today's Business Solutions). We use there ePRINTit for mobile printing, PaperCut MF for Print Management and Easy Booking MYPC for time management for our public computers.

We also get a portal page for patrons to load documents or pictures to print when they arrive at the computer lab.

While I don't handle setup, implementation, or updating of any of this
type of software myself, my employer participates with our county
cooperative staff (Suburban Library Cooperative in Macomb County) in
that the Hardware Software Specialist of SLC helps with this in
conjunction with our Operations Manager who has the majority of IT
duties here.

Speaking in my own capacity and relatively limited role as a Technology
Services Lib. with ~12 years exp.,  I can tell you this from our
hardware setup:

-Envisionware LPTOne for print management (as you stated, IIRC, doesn't
apply here)

-PC Reservation Reservation Station (despite the reputation online -
e.g.
https://www.reddit.com/r/Libraries/comments/18gpbh5/does_anyone_use_envisionwares_pc_reservation/?rdt=57150),
I rarely encountered problems working on the service desk and helping
patrons who are logged onto our public PCs.  99.9999% of the time, we
don't have to use the reservation feature.  PCR Control Panel, settings,
PC usage stats from what I've seen seem to work very smoothly and
consistently.
Also, to note, I am not precisely sure how Envisionware's LPTOne and
PCReservation work together, but I found an example of a PR release
explaining features from a library patrons perspective of sorts:

-Faronics' Deep Freeze Standard - it has largely proven consistent and
reliable over the same ~12 years I have worked with it on our Adult
Services public PCs!  Currently up to v9.something.
FWIW, you can also read about DF Standard's release notes and known
issues, too:

Additional Info for our setup:
-Toshiba 2505 AC Multi-function Scanner/Copier/Printer
-20 Dell Optiplex AIO PCs (7410s?) for public usage- currently have
Windows 10 22H2 installed; we're most likely updating the PCs to Windows
11 24H2 by this October because of Win 10 EOL.
-Envisionware X11 self-service station for printing and copies - having
a supremely difficult time with it in those functions, even if
self-checkout of items on it works near-seamlessly.
