Dell Printer Custom Format

Found this article, which was really helpful, thanks a lot llanelli14 !

Well it’s that time of the year again when I print out Xmas cards for my young students to color in or decorate.  I use simple black and white stencils on colored card.  The card size is best described as B5 oversize.  So it needs a custom setting in the printer menu of my 3110cn.  In Windows XP this was an A-B-C operation from the printer’s configuration menu.  In Windows 7 it required some lateral thought.

If you open up the printer’s configuration menu: Start, Printers and Devices, RMC 3110cn, Printer Properties, Configuration tab, Change Paper Size – you get a listing of the twenty Custom Size settings (all identical 210x297mm).  But the adjustment controls are grayed out.  Aaargh!

After loads of clicking I finally decided to try the Administrative Tools in the Control Panel.  Hey Presto!  Start, Control Panel, Administrative Tools, Print Management.  Double click All Printers.  Select the 3110cn and RMC and select Properties.  You get the exact same top menu as above but when you hit the Configuration tab and click on Change Paper Size the adjustment settings are accessible.  Excellent!

Obviously someone incredibly wise will be able to tell me why this was possible.  For the meantime I’m just happy I can print my Xmas cards and my students can color away and that’s another week of December lesson-plans completed!

Hope this helps someone.

Doing so, I was able to create a custom paper size for my Dell C1765NF. So I could use my custom size envelopes, in the manual feeder, just used “Custom format” in the menu (in the printer’s LCD diplay). Et voilà :-)

How to fix strange Windows 7 Update errors

1. Run System Update Readiness Tool

2. Check log-file C:\Windows\Logs\CBS\CheckSur.log

3. For me it stated
Unavailable repair files:

4. Start Windows Update (also [!] if it fails – important for the next step; the HKLM->Components hive is loaded by doing so)

5. Start regedit

6. navigate to HKEY_LOCAL_MACHINE\COMPONENTS\DerivedData\Components\ and search for (in my case) amd64_microsoft-windows-trapk_31bf3blahblahblah

7. export the keys

8.  delete the keys

9. try to update Service Pack 1

Lazy Lookup mapping

Can be used to cache values from database

     private static Lazy<Lookup<string, string>> MyMappingLookup = new Lazy<Lookup<string, string>>(() =>
            using (var session = SessionFactory.GetSession())
                var result = session
                                .CreateSQLQuery("select foo, bar from whatever where bananas")
                                    values => values[0].ToString(),
                                    values => values[1].ToString(),

                return (Lookup<string, string>)result;

        private static string CheckOrConvertBanana(bool convert = false)
            var code = "red_pyjamas";

            if (string.IsNullOrEmpty(code) || !MyMappingLookup.Value.Contains(code))
                // not found, warning...
                if (convert) code = MyMappingLookup.Value.First();

            return code;
