horizontal lines are hatched and not solid

[oefm007]

I print a lot of architectural drawings, when I do, the horizontal lines ALWAYS come out as a series of tiny hatched diagonal lines rather than a solid one. I have done all of the printer tests and everything is normal, I have also played around with all of the settings when printing, nothing works. PLEASE HELP!! I have attached a drawing to show

To assist better -

1. Does the issue occur when copying as well?
2. What's the application you are trying to print from? Have you tried printing from a different application or device? 

Let me know!

 Try the below suggestions -

 Use HP Print and Scan Doctor to check connectivity

Download a special version of HP Print and Scan Doctor specifically created to help with printer offline conditions.

1. Download HP Print and Scan Doctor.
2. Run HPPSdr.exe from the download location on your computer.
3. Once HP Print and Scan Doctor opens, click Start, and then select your printer.
   • If your printer in not in the list, turn it off and on, and then click Retry.
   • If there is a connection problem, follow the instructions in HP Print and Scan Doctor.
4. If a screen prompts you to turn on printer updates, click Yes.

Check the printer driver settings. Refer to the document for help- HP Printers - Print Driver Settings Guide (Windows)

If the issue persists, Let's try and uninstall the printer software from the root level on your PC and install the full feature printer software.

--->Select your HP printer.

--->Select Uninstall.

--->In Windows, search for and open Devices and Printers.

--->In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”

--->Open up the run command with the "Windows Key + R" key combo.

--->Type printui.exe /s and click OK.

--->Click on the Drivers tab.

--->Look for HP Printer driver. If you see it click on it and click remove at the bottom.

--->Select OK.

--->Select Apply and OK on the Print Server Properties windows.

--->Close Devices and Printers.

And then reinstall the printer's full-featured drivers from https://support.hp.com/in-en/drivers/selfservice/hp-officejet-pro-7740-wide-format-all-in-one-printe...oftware and drivers page s

Let me know how this goes!

Let's try and uninstall the printer software from the root level on your PC and install the full feature printer software.

First, unplug the USB cable from the printer if present.

• Go to Control panel – Programs and feature – Select all the HP printer entries and uninstall them.
  • Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
  • Restart your computer.
  • Click the bottom-left Start button on desktop, type device manager in the search box and tap Device Manager on the menu.
  • Once in device manager, click on the view tab in the top & choose “Show hidden devices”.
  • Then from the device manager list, check the entries under “Printer” – If there are any entries, please right click and choose “uninstall” – In the confirm device un-install pop-up, make sure you select the box which says “Delete the driver software for this device". 
  • Also, check the entries under "printer queue" and "imaging devices" and repeat the same exercise. Delete any printer entry or any entry which says “Unknown device”.
  • Once done, close device-manger. Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.
  • Under print server properties, go to drivers - remove any entry there as well.
  • Again, go running window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
  • Once done you can try cleaning out your temporary files and cached files. You can try using automated applications like some cleaner software's that you can download from the internet.
  • Now restart your computer again.
  • Open the Run window again, type “services.msc” and press ok to get services window.
  • Scroll down to “Remote Procedure Call (RPC)” – right-click and go to properties. Make sure the service is started and startup type is “Automatic”.
  • Now scroll up and go to “Function Discovery Provider Host” – right-click and select properties – Change the startup type to “manual” and start the service.
  • Repeat the same exercise on “Function Discovery Resource Publication” as well
  • Windows image acquisition stop and restart the service 

Install all the available Windows updates

If it is been a while since you updated your Windows, that is the main reason why Windows says your HP printer driver is unavailable. Here are the steps how to do a Windows Update to install all accessible operating system update.

If you are accessing Windows 10, then these steps are for you.

1. Hit the Start menu and write an update. After that, click on the “Check for updates” option.
2. Tap on the “Check for updates” option.
3. After clicking on that option, Windows will install the updates automatically.
4. When Windows completes all its updates, start your computer again and attempt to print a file to check if your printer works.

Reinstall the drivers from the Software and drivers page

If the error persists, Try installing the printer with a windows built-in driver

Hope this helps! Keep me posted.
