Sir,
I went through the entire upgrade log from 2014.135 to current 2015-109, and there were no changes to anything related to printing.

Can you make 2 tests please.
Read the qimagepr.ini file using Notepad, while you have 2014.135 installed. (What does it say(There's only one line))

Then please disable your ANTI VIRUS software (Most AV software have a temporary disable feature ) and download a fresh copy of 109.

Reinstall the latest 2015.109, (and please disable the AV software for the install also.

Read the qimagepr.ini file again.

Fred

Thanks William for chiming in!  A questionable cable is certainly a possibility.  I compared 2014.135 and the latest 2015.109 and both are identical with respect to the code that gives that message about "no printers found'.  It's only one command that Qimage Ultimate is calling at that time: a Windows API command called EnumPrinters.  That command is supposed to return the number of Windows installed printers on the system.  The only way to get that "no printers found" message is for Windows itself to return zero to that function, indicating that no valid Windows drivers have been found or that the printers are not available.

The difference between Qimage Ultimate and other software is that Qimage Ultimate queries the system for valid printers as soon as you start it: because printing is a primary function with Qimage Ultimate.  When you start other software, they don't care about printers until you go to "File", "Print" and that function may not have a problem if it's an intermittent issue like bad cabling.  So QU may show the problem right away yet you may not have a problem in other software... or you may not have a problem right away and may have intermittent issues along the way (later).

As Fred said, anti-virus software is probably a good thing to rule out.  Disabling AV software and retrying is a good idea but unfortunately, no AV software can be completely disabled by using the AV built-in "disable" function: it has to be uninstalled completely and the machine rebooted to rule out interference by AV/anti-malware programs.  Needless to say, these are the only two reports I've seen and with so many users using QU, it's likely a local problem.  So AV interference (AV software denying QU access to printer information) and bad cabling seem like logical things to check.  That 2014.135 works in one instance and 2015.109 doesn't: might just be a timing issue.  The code is the same.

Regards,
Mike

Just to clarify,
Qimage is checking for installed printers properly registered in Devices in Windows.
It doesn't know or care if the printers are not turned on yet.

Fred

My Qimagepr.ini is 4 kb.
Try HELP RESET PRINTER
If that doesn't change the file. Then delete it.

If you are reading the file using Notepad, you will see a horizontal scroll bar. It's a lot more than one line

Devices and Printers

That is what my devices and printers looks like, just with different types of printer.

I spent some time this morning trying to purposely mess up my system to emulate your problem.
I installed Qimage on a separate hard drive. I did that to change the default setting in the install wizard to set different location.
The reason for that is that the Qimage installer remembers the last location it was told to install.

Maybe, somehow you had two installation locations and it wasn't overwriting?
Nope. It overwrites and it installs in any location, and a reinstall over it with a different version (old or new) lays right over the previous one.
I installed on a non bootable drive; just a storage drive, and Qimage still sees the printers.
I reinstalled back to the normal  C: drive, remembering that there is a place to set the install location and again, another place to set the location of the DATA files.
I messed that up on purpose, and still, other than not knowing where to look for my history of used folders, Qimage found the printer.

I am convinced the problem has to be NON QIMAGE. It may be something related somehow, but it cannot be any buggy code in the program.
Maybe someone has an idea to try, but I am fresh out,.  Maybe Mike will have something he can test with you.

Hopefully, Fred

I can only state what I've said before: this is not a QU issue because it is not QU that is reporting no printers installed.  It is the Windows operating system that is reporting zero (to QU) for the number of printers installed.  Since the code in 2014.135 is identical to 2015.109 and 2015.110 and you get different results, it appears something is interfering with Windows communication to QU so my bet is still on your Comodo Internet Security software.  Anti-virus software cannot be fully disabled without uninstalling it completely.  I did find several hits where Comodo's firewall (a part of their Internet Security Suite) was blocking printer drivers.  Although this is a shared printer, here's one example:
