Hello,

Android is quickly becoming a full-blown O.S, a desktop replacement,
the need for Printing abstraction model arises.

Why ?

To avoid the need to install device-specific drivers as we do on
Windows PCs for every client, and for every printer model we intend to
print on.
Also today, without common printer abstraction layer, when upgrading
an OS, you may be required to purchase a new printer, and upgrading a
printer may force you to upgrade an OS.

Today Android devices *do not* support printers at all. (excluding the
Samsung Galaxy SIII proprietary feature, that can print to certain Samsung
Printers.)

There are two printing abstraction layers in existence, that I know of:
1. Google Cloud Print (supported by Chrome browser and Chrome OS, but
not by Android)
This idea is very innovative: "Google Cloud Printer"-enabled device is
a printer, that just connects to your GMail account, and let's you
print from anywhere on any of your printers.
The benefits of the Google model, is that it is really simple and a
conceptual innovative ! The downside, is that if the Internet is down,
you can't print at all. :(

2. Windows 8 model (supported by Windows RT and 8)
Windows RT is similar to Android in the concept, that there is no way
to install 3rd party printer drivers on after-market devices
(post-purchase).
So Microsoft went in and developed a brand new abstraction layer model
for their Windows 8 and RT systems. Previous versions of Windows
(XP/Vista/7) never had an abstraction layer, but Win 8 does !
This idea is great, because it bring the familiar LAN-based printer
sharing, but uses abstraction layer.
Windows 8 / RT using a class ID to speak single super-language to all
new printers.
The benefits of this Microsoft model, is that it is
offline-compatible, and works even if the Internet is down ! (which
happens quite a lot in my home)

3. Add Printer API & common GUI to allow Android programs to use printers.

I would like to request to add both printing models to Android.

(in GNU/Linux, the CUPS model is completely broken, just like in
Windows XP/7, because it does require specific drivers all the time...
Related issue: "

Issue 36905843

: RFE: CUPS support for printers". But CUPS is out of question due to inherent limitations.

Hi there,

Thanks for reporting this. Do you mind attempting to install again? If there's no bin/ folder, that suggests an incomplete installation.

I installed again and again, uninstalled, installed for all users, not just me, everything. Doensn't help.

Maybe this helps:

Thanks for the additional information.

Looks like your Python installation is having a hard time connecting securely to Google. What Python version are you using? What happens when you run

> python -c 'import urllib2; print urllib2.urlopen("

https://dl.google.com/").read()'

using that Python installation.

We need to do a better job of detecting when the installation fails.

I'm using python 2.7.10.

As far as I can tell, it is the same error.

>>> import urllib2; print urllib2.urlopen("

https://dl.google.com/").read()

Okay, then it's a problem with the way Python is hooked up to your computer's certificate store, or a problem with the certificate store itself.

Can you try connecting to that URL using a web browser (one that's not Chrome would be great, since I think Chrome does some funky stuff with its certificate stores). IE or Edge would be great.

Well, I'm not really good at reading or writing code, so the only thing I can see it should download

https://dl.google.com/dl/cloudsdk/channels/rapid/google-cloud-sdk.tar.gz

I downloaded this file using browser, extracted it and tried executing install.bat because I'm on windows.
This happens:

Welcome to the Google Cloud SDK!

Do you want to help improve the Google Cloud SDK (Y/n)? Y

This will install all the core command line tools necessary for working with
the Google Cloud Platform.

Upon further research, it looks like you're hitting this OpenSSL bug:

I just downloaded Python 2.7.9.
It worked! Thank you!
