I have faint but noticeable horizontal lines on prints from my Photosmart Pro B9180.
When printing grey scale pictures on my Photosmart Pro B9180, I can see faint horizontal lines not quite 1/4 apart. I have aligned the heads and cleaned them 3 times and the lines remain. The Head analysis indicates that three of my heads are in fair condition and one is in good condition. I also notice when the print out after head cleaning is on glossy paper that multiple lines appear in virtually all the color swatches. I have not received a "replace printhead" message, but I'm beginning to thing that is the next step. Any insights?
This document may help. I have a feeling the manual cleaning section may be applicable:
Banding, streaks or lines

I have an older HP connected to the usb port of my Time Machine, and have it shared. I want to print from my iPhone on the network, but it can not be found in airport? How do I make this work?
AirPrint printers connected to the USB port of the Apple AirPort Base Station or Time Capsules are not supported with AirPrint.

I have a HP Officejet Pro 8500A and I had no problems printing to it from my Mac or Macbook pro. The macbook is wifi and the Mac is cable, I have recently had the printer replaced with an exact model. Since doing that I can only print from the macbook pro, when I try and print from teh mac it doesnt see the pages. It could be a 10 page document and it will just show two blank pages. I have googled the question and have tried deleating the printer and reinstalling without any luck. When I got the new printer I insalled all the latest drivers thats the only thing different.
Could you please help
MichelleRight click the printer in System Prefences - Print & Scan and use Reset Printing System... and then reinstall the printer, should take less than 5 minutes. Here is a photo showing how to Reset Printing System....

PDF prints from Acrobat 8 Pro, but not from Acrobat 9 Pro
I have a PDF that prints fine when I print from Acrobat 8 Pro, but when I open the same PDF in Acrobat 9 Pro, only portions of each page actually print out.
All systems running Windows XP Pro, SP3
A8P 8.1.2
A9P 9.1.1
Any ideas?Well, for those following this thread or needing a solution, I found a work-around though I'm still not sure why the initial problem exists.
In Acrobat 9 Pro, once you have the main print dialogue box open, follow the steps below:
1) Click ADVANCED
2) Select PRINT AS IMAGE
3) Set DPI to 300
4) Click OK
5) Make any other typical print setup adjustments as you normally would and finish printing as usual -
I have a new Macbook pro and need to run some Windows software, it appears "Parallel" should work well from what I've have read. Will I have any issues or problems accessing and printing from various printers on my Windows 7 network within Parallel? Is Parallel in fact the best way to go?
First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long. -
My new Hewlett Packard printer is listed as an AirPrinter on the Apple website, but when I try to print from my iPad it says that there are No airprinters. The printer is connected to the same WiFi network, is turned on & I'm close to the printer. Do I need to forma/set up the iPad or Printer to enable this feature?!
It would help to post this in a more proper form. This is for the iTunes family of stores.

Check out the article below for troubleshooting your issue with the display. There are a few things that can be done, like changing the resolution of the display and also to reset the NVRAM to see if that resolves that for you.

My laptop just received a new motherboard and I just reinstalled RoboHelp. All of a sudden, when I try to print a topic, whether it is from a generated .chm file or a preview within RoboHelp, all horizontal lines are missing, regardless of size or color. This is causing a major henderence in the reviewing of print copies for editing purposes.
I have made sure it was not a color or line issue but printing from other programs and different images-they all print fine. The problem is isoloated to RH (I am using version 7).
I have attached two screenshots I took of examples of lines that are nort printing.
I have checked the printer settings-they match the settings used in all other programs.

Black horizontal lines when printing
The printer prints all black horizontal lines on several pages wehn starting to print or copy. totally black and unreadable. After several pages, it gets better, but still is not a totally clean print. I have reveiwed all your suggetsions. The scanning works fine, only printing is a problem. I have cleaned everything, replaced print cartridges, but nothing works. Someone supggested there is a controlling cartridge that my need to be replaced. I cannot find any information on this anywhere. Please help, thank you, Pam
Can you scan a print showing the defect and post it here? It would help to understand the nature of the lines and at what space they repeat.

Horizontal line appearing on the Mac Book Pro 13" Retina Display
I RECENTLY BOUGHT A 13"RETINA DISPLAY MACBOOK PRO. IT IS SO DISAPPOINTING. THERE IS A HORIZONTAL LINE THAT APPEARS ON THE SCREEN AND DISAPPEARS. THIS WAS FOR THE THIRD TIME I HAD TO FACE THE SAME ISSUE. WHEN I EXPLAIN TO THE STAFF AT THE APPLE STORE THEY SAY THAT THEY HAVE NOT COME ACROSS SUCH ISSUE, FOR WHICH I SHOWED A PROOF FROM THE OTHER PART OF THE WORLD. VERY DISAPPOINTED.APOLOGIES TO WRITE IN THE UPPER CASE.BUT IT IS FRUSTRATING WHEN YOU HAVE A LOT OF EXPECTATIONS FROM APPLE LAPTOPS.
Thanks. But What at the most they can do. They are going to tell me to take the laptop to the apple store.

MBP 17" 2010: horizontal lines extending out from open windows on 30" ACD?
I have a mid-2010 17" I7 with anti-glare screen. The topcase was replaced for factory damage and now the screen was replaced by Apple here in Paris, where I live. I use the MBP with a 30" ACD at home, with no problems until I picked up the repaired MBP yesterday with new screen. I now notice that when I open a window, like Safari or Mail, the lines (let's call it the lower line that frames the menu bar in grey on the top of each open window) seems to extend beyond the open window and run across the top of the entire 30" display. If I move the window, that line moves across the screen with it. It doesn't occur on the MBP screen itself, only on the attached 30". So that if you open Safari and place it in the center of the external display, you see the line running from the grey menu bar on top of the window extend out in both direction across the entire display. It has no effect within the windows you are looking at all, but this wasn't there, or I never noticed it before. I changed the desktop background to see if it changed, and basically not, except it is not viewable so much with light or white background.
There is no effect within the windows being viewed. It's as if the line running out from the frame of the window, especially the bottom part of the grey menu bar on top, are extending out across the screen.
Any suggestions would be greatly appreciated.It turns out that I tested my 30" ACD with a friends Macbook and it has the same phenomenon. It's quite strange. The darker the blue or grey the more this line flows out from the grey bar frame on Safari or Mail windows. The smaller the window the less evident the phenomenon. Again, it has no effect on the windows themselves, and only occurs toward the top of the display. When you move the window down on the screen it disappears. And it is only the line below the grey upper bar that is rather bold that bleeds out across the screen.
I wonder if there is a way to reset the display or move to some default setting that would correct this.
