HP7740 Scanning Software

HP Recommended

First time on the this forum. . .so be gentle.   Apologies if there is a better place to pose this question.


I have a HP7740 printer/scanner.  It has a legal size sheet feeder and Tabloid (11x17) scanning glass.


So - - - about the scanning software. I am working in a Win10 environment.


I see references to "HP print assistant"; but I can't find a place to download it?

I seem to be directed to the HP Smart App.

The HP Smart app itself seems to work. . . . .BUT for a simple scan; it seems to want a log-in to a webservice.  WHY? I need a reliable alternative that does not require web access. Simple security concern.


SO. .  .I have also found a program called "HP Scan and Capture".  . . supposedly from HP.  This issue is that this program will only scan Legal Size when you select "entire Glass". The issue is that this is a Tabloid (11x17") scanner.  The "Scan" function of the "HP Smart App" will scan Tabloid without fuss.


This problem seems to be shared by other applications that seem to use a twain interface (i.e faststone and Adobe Acrobat).  



Frankly. . .. I don't need a fancy program; I can import documents into fancy programs to do fancy things.  All I am looking for is the ability to scan 11x17 documents.  Basically, the "Scan" function of "HP Smart"; without the internet connection.





Edit:  I just found this thread:   Solved: HP smart requiring sign in - HP Support Community - 7817547

The question appears to be "Why do I now have to LogIn to use a local scanner?"

The answer appears to be a politely worded "Suck it up Cupcake 🙂 "


I would submit that while it may be the answer; I find the answer to be unacceptable from a Cyber and Privacy perspective. I really do need a way to scan 11x17" locally without internet contact. I am perfectly fine purchasing a more consumer friendly solution.

Hey - 


- Thanks for the quick feedback.


I had tried HP Scan and Capture with no luck earlier today. . . .but when I went through the Easy Start after reading your post, it sure "looked like" I had a new set of drivers  installed (I thought I had the latest. . .apparently not)


With the new TWAIN driver, it seems to REALLY want to default to a  8.5" width; but "entire glass" setting does seem to work. . .although it looks like the resulting images have an 11.69" as opposed to a 11" width.  I am not finding an 11x17 preset.  Well, there IS an 11x17 preset in the twain driver, but it produces an 8.5x17 image.


I need to actually get something done now; so I will fool with this later.


Thanks for the help.
