HP printers, iMacs and WiFi

-

Do you have problems printing to an HP printer over WiFi from your OSX / Mac device? I've seen this a couple of times now: at home and also at my parents' house. Different machines, different printers but very similar symptoms (a year or so apart). In both cases the symptoms were slow/unusable printing as soon as documents were more than plain text and in some cases the print failing altogether. The problem seems to stem from the default airprint driver that your OSX device will helpfully install for you. You need to change this to the device specific driver as per the below instructions:
  1. Click the Apple icon on your Menu Bar. 
  2. Select System Preferences. 
  3. Select Printers and Scanners. 
  4. Select your printer and then press the (-) button at the bottom of the list to remove it. 
  5. Select the (+) and click Add Printers and Scanners. (NOTE: Do not select the printer from the list of Nearby printers as this will often automatically use the AirPrint driver) 
  6. Select your printer (the one that shows Bonjour Multifunction under "Kind"). 
  7. At the bottom of the window under Use: does it say AirPrint? If so, click the drop down and you should see a specific driver for the printer. Click Add. 
  8. Try printing an image again, all should be fine.....

I had problems getting an HP M252dw printer to automatically duplex when a Windows machine printed to it - kept trying to manually duplex. Turns out you need to manually tell Windows that a duplex unit is installed as shown in this YouTube video - https://www.youtube.com/watch?v=vRZrAb4JDPY

Using Python to Automate Visio

-
There are lots of examples of automating office apps out there but Visio examples seem thin on the ground. I guess this is partly due to its relatively recent inclusion into the Office fold. The example below shows Visio code to create a diagram with two rectangles joined by a connector. Its written in Python and makes use of the win32com package provided by pywin32 . This is installed by default with ActivePython . I had some difficulty getting the makepy tool to see the Microsoft Visio 11.0 Type Library that showed up fine as a registered object in Visual Studio and Excel/VBA. In the end I had to explicitly point makepy at the VISLIB.DLL. That said the code below will work fine without this step as I don't make use of any of the Visio Constants. import os import win32com.client # Two lines below generated from the command: # python makepy.py -i VISLIB.DLL from win32com.client import gencache gencache.EnsureModule( '{00021A98-0000-0000-C000-000000000046}' , 0,

Microsoft accounts for children - Verify that you're an adult error

-
I recently bought a Windows 8 laptop for my son for his school work. However, after logging in with his email address (also used on an Xbox) he was unable to use any online features which are pretty key to Windows 8 and Office 365. As it was a child account he got prompted that he "needed permission to use this service” and to have an adult sign in. However, when I signed in as an adult to authorise this I was redirected to the following broken page: https://account.live.com/ChildConsent/PaymentCollection Verify that you're an adult Error When you verify your age with a credit card, Microsoft charges the card a one-time fee of $0.50 (50 cents), and a portion of the fee is donated to charity.

The computer says no

-
I thought I’d finally bite the bullet and try to upgrade my parents broadband to a new provider. They have been on Demon forever, but the service has atrophied as they were first bought by Thus and then Vodafone. I visited the PlusNet and BT websites to find out what packages they could switch to only to end up with some rather strange errors: You don't have a compatible phone line. To provide you with a new service we will need to give you a new phone number The phone number and postcode supplied do not match; please try again. An online chat with PlusNet resulted in an impasse. Despite my parents having the number for 30 years apparently it wasn't valid and a new number was required - the computer says no! A bit of googling took me to the excellent BT community forums which showed this is a problem that other people have had. All the providers reference an Openreach database which contains phone numbers and addresses. It's entirely possible for this database to co
