Welcome to INVENTPEACE.COM COMPUTER and PRINTERS Tips n Tricks !

 PRINTERS: How to make the default print color Black and white only for HP (and other printers).

 While most of us know that if you clik on file, then print, you can see an icon that says preferences", then clik on color tab and choose, grayscale and b/w only, it makes you do it every time from your application which is annoying.

   BUT THE GOOD NEWS IS :  you can do that same action from the control panel, printers, dbl clik on the printer in question, then "adjust print options" or preferences or properties (depending on your windows version), then clik on "color tab" as above, then you  clik on grayscale only AND black and white, HERES THE GIST: if you try to make it the default by choosing that in the little window or if you type in "default settings, etc)  its asking you to "save" it as, it won't take it, BUT  if instead you simply clik on "APPLY" and then "ok", it takes it and you can now not have to redo the choice every time you print SAVING THE EXPENSIVE COLOR INK and the TEDIUM having to change cartridges and choices.  (even though the little window says type in a file name, it then takes it as the new default) YAY !!  The point here is to do it from the control panel printers option and don't try to use the save button, instead just clik on apply and then ok.  If you want color do the normal ; file -->print -->preferences-->choose color, and it will do it for only that one time. 

   PRINTER WON'T PRINT in black but will in color, (or vice versa), clean cartridge that is not working (assuming it has ink in it), with a q-tip on the head area, A good cartridge will leave a small black rectangle on a paper towel pressed against it, if not; use alcohol to clean the head (q-tip again) being sure to clean it very thoroughly, keep cleaning unti you can't get any more old ink off.  ALso clean the contacts on the back of the cartridge, you can use the alcohol again but also use your finger nail to lightly scratch the contacts so that there is no black or worse green on the contacts and that the contacts are bright and clean, also check the inside contacts where the cartridge plugs in to make sure they are also bright and clean.   It worked for us. 

   INK TIP:  you can extract ink from one black cartridge with a special extractor (looks like hypodermic needle but much bigger needel (maybe 2mm), push the needle into a non working black cartridge thru the hole in the top, extract the ink, then insert the needle into the good cartridge again thru the hole in the top, gradually add the ink (you may have to peel off the manufacture sticker to see the hole).   It worked for us. We think the ink is a special type that only works with for example our HP printer, so when doing this it would probably be best to use ink from non working or wrong type "same brand" cartridge.

IF all that fails, Goto Home Depot or Office Max and buy their store brand.  We ordered from EZ ink off internet but neither cartridge worked.  

COMPUTER PC PROBLEMS:

WINDOWS UPDATE for WINDOWS 7 -  SLOW PROBLEM: 

RE:  Windows 7 Service Pack 1 for x64-based Systems (KB976932)

Download size: 73.6 MB - 892.6 MB

DON"T DO IT  ! ! !  Theres something in there that makes your PC run VERY VERY SLOW (like 10x slower).  
IF you already did the update you can go back to it and uninstall it .. this puts your pc back to where it was before the update.. (I think its cntrl panel, software and programs, then find Windows 7 service pack 1, and uninstall it.. you can "try"  "system restore" but when you update most all of your previous restore are erased, but there may be a place to uninstall or restore pc to pre-update .  ( I truly did the update, went thru hell trying to figure out why the pc was so slow, and eventually did the rollback to pre-update (uninstall service update) status.  Now it works good as it did before the update.

SOUND AUDIO NOT WORKING IN SAFE MODE WIN7 XP

SOUND AUDIO NOT WORKING IN SAFE MODE WIN7 XP
First:  Why use "SAFE MODE"  ?  Its because "safe mode" uses less resources so that things like streaming video work more smoothly than normal boot up.  To get to safe mode" simply restart pc, and tap on F8 every second during the startup... it will go to a special screen which allows you to arrow down to "safe mode with networking", which in turn allows you to use the internet and do tihngs like streaming video, email, etc.   MS blew it by not making this already work in safe mode (or maybe they did it on purpose to force us to buy always newer versions of their windoes? ) 

In good we trust!   This should enable the pc speakers but maybe not the HDMI speakers. 
Enable audio in safe mode WIN7 and XP 

!!!!  WARNING !!!  (backup data first, make sure you make a new "restore point" in the case of tragedy, I don't recommend fooling around with the registry (via regedit) except in this one case only.   You can think of the registry as a better version of the old "FAT table from DOS days, but its more than that contaning alot of system info that directs how your pc operates or not.    

 How to do it in Windows 7: ( from internet solution slightlyaltered to work for win7)

Login to your pc with "Administrator rights (so you can change things in registry).  

Goto computer , "manage", choose device manager
Find the "Sound, video, and game controllers" in the list, open it, choose the audio driver ( if more than one listed its ok, the part of the driver key in should be the same) ,  open it, 
Find the details tab, clik on it, under "property" open the window and find "driver key",  copy the whole key to notepad or other area where you can edit the copied string.   Change all lowercase letters to upper case (paste it twice in notepad then edit 2nd one using first one to check your work,),  now copy the all upper case string between the  brackets. It shoul look similar to this :   
{4D36E96C-E325-11CE-BFC1-08002BE10318}    
Although your particular one may be slightly different.  Do not include the {input}00 or {input}01 which will appear after the brackets
  Now clik on start, type in regedit, click on enter, then navigate to KEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSafeBootNetwork
Create a new key (right-click, select New → Key)  ,    Paste the string  you saved into the new key name
Edit the (Default) (Rt click on where it says default and select modify),  change  the value to:  "Sound, video and game controllers"
Create several new keys (under Network) called AudioEndpointBuilder, MMCSS and Audiosrv
Edit the (Default) "values" of each of the new keys and change each one to "Service"
Reboot (boot into safe-mode by tapping the f8 key every one second while the startup process is ongoing, it will give you a menu, choose the safe boot with networking option and hit enter)
  After p_c starts in safe mode let it settle for a few minutes, then try a  program that uses sound such is streaming video. if the sound does not work you can try the following:
clik on start and type in services.msc
Start the Multimedia Class Scheduler, Windows Audio Endpoint Builder, and Windows Audio Service services.  you may have to reboot again to get it to work just repeat restart comma tap f8 key every one second while startup is ongoing and again go to the safe boot with networking option. remember this was to make the audio work in safe  mode, so of course you have to restart in safe mode for that.   
      It may only work with the computer speakers ( better than nothing)  I have not been able to get it to work in safe mode with the h_d_m_i cable to a television.Best of luck


This is how to do it in Windows XP:

Run (⊞Win+R) regedit
Press Ctrl+F
Make sure Keys, Values, and Data are all selected
Type in Sound, video and game controllers
Click [Find Next]
Take note of the branch address in the status bar at the bottom (it will be something likeHKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E96C-E325-11CE-BFC1-09002BE10318})
Copy the device-driver GUID (the long numeric part between braces) and paste it somewhere like Notepad
Navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSafeBootNetwork
Create a new key (right-click, select New → Key)
Copy the GUID you saved and paste it into the key name
Edit the (Default) value and type Sound, video and game controllers
Create several new keys (under Network) called AudioEndpointBuilder, MMCSS and Audiosrv
Edit the (Default) values of each of the new keys and type Service
Reboot (you’ll boot into safe-mode)
Open the Services snap-in (⊞Win+R → services.msc)
Start the Multimedia Class Scheduler, Windows Audio Endpoint Builder, and Windows Audio Service services

If problem persists try to change the Khz sample rate (may be tricky, be sure to write down all settings and what exactly you did so you can put it back at least to what it was.
