just recently brought an acer one 722 with win 7 os. I have a problem with connecting my printer with the computer. I tried plugging it in the 3 different usb port but it is not detected by my computer. My deskjet is old but it works perfectly well with my samsung netbook. Can anyone help me pls? thanks
I found some topics in the internet about the incompatibility and how to make it compatible but it is not working for me. ( I did a snapshot of the step by step process but cannot figure out the last step)
this is the guideline that I saw from another site I cannot post the file so will paste it here:
The attached file contains a patch for this issue. Apply the patch as follows: First make sure the driver for the printer is installed. Log into the computer with an administrative account. Download the patch by clicking on this link or on the paper clip at the end of this post. Save the patch file to your computer, then unzip it. Next copy the three DLL files to the following directory: %windir%\system32\spool\drivers\x64\3
This can be done from a DOS prompt if DOS is opened with the "run as administrator" command, or from explorer with a copy and paste. Depending on your UAC settings you may need to provide confirmation. Also allow the current files to be overwritten if prompted.
This patch is not required and should not applied to a 32 bit version of Vista or Windows 7.
Thanks to extraordinary Microsoft engineer Alan Morris for guidance for the patch.
Update - the following are more detailed installation instructions:
Download the patch from here. Now click on the file and open it, then extract the patch to some directory that is easy to find. (I use c:\temp. If this directory does not exist you can create it as follows: open the administrative DOS prompt by clicking on Start, All Programs, Accessories, then right click on CMD.EXE and select Run as Administrator. Click in the DOS box then type the following:
Step 1 - MD c:\temp
Step 2 - CD \temp
Now extract the patch files into the c:\temp directory (extract all, chose c:\temp as the destination).
[Update - Windows security settings may prevent these files from being used, please open Computer, type c:\temp in the address bar and then right click on each of the dll files and select Properties. If there is a message in Properties indicating the file was downloaded from the internet and may be blocked then unblock the file before proceeding.]
Next click back in the administrative DOS prompt and type the following: (stuff in green is comments, do not type them...)
Step 3 = DIR *.dll (this is just to verify the files are there, it should list hpvdb720.dll, hpvdb820.dll and hpwm5db1.dll and perhaps others.)
Step 4 = Net stop spooler (makes sure the files are not in use.)
Copy hpvdb720.dll C:\windows\system32\spool\drivers\x64\3 (this is for the Deskjet 710/712/720/722)
Copy hpvdb820.dll c:\windows\system32\spool\drivers\x64\3 (this covers the Deskjet 820 and 822)
Copy hpwm5db1.dll c:\windows\system32\spool\drivers\x64\3(this covers the Deskjet 1000)
Net Start Spooler
At this point the patch is installed and ready to print.
Note that the printers here do not support USB connections, they have only parallel ports. If you use a USB-parallel converter make sure it is supported in your operating system. The following posts are flagged with USB-parallel cables that are reported to work in Windows 7. A driver is required for the USB-parallel converter in addition to the driver for the printer. For supported converters this is typically supplied automatically in Windows 7. Note: the proper port to select for the USB-Parallel converters is often USB001:. I have heard of some cases where the port was USB002: or LPT3: as well. If the port you are using does not succeed (after applying the patch) try changing the port by going to Start, Devices and Printers, right click on your printer and select Printer Properties, then click on the Ports tab.
I cannot post the snapshot here
