Microsoft Windows 7 for Print to Fax

Fax Guy Shawn recently shared with me a common RightFax issue that he has encountered while helping our support customers and he thought you would want to be in on the scoop too! Not all issues can be remedied via simple instructions and screenshots, but this one is pretty easy to follow. Our hope is that you can get through this one alone, but if you need us, we are here.

Basically, anytime a print driver is updated on the Windows 7 operating system with FaxUtil installed, some advanced properties on the RightFax Fax Printer get reset.  In order for Print to Fax to resume functionality, these settings need to be modified back to the way RightFax likes.

There are two special considerations for Microsoft Windows 7 for Print to Fax:

  1. Windows 7 does not include the HP Laser Jet 4 printer driver.
  2. If any print driver is changed in Windows 7, the print processor for the RightFax Fax Printer is reset to Windows, preventing the fax dialog from appearing.

The location where this can be changed back is as follows:
Windows 7 Printer Issue

Devices and Printers -> RightFax Fax Printer -> Right-click, select Printer Properties -> Advanced -> Print Processor

Windows 7 Printer Issue 2

This will default back over to winprint if/when any driver is updated. This should be set to RFPrint in order for Print to Fax to function correctly. Also note that the HP LaserJet 4 printer should be selected.

This is the location of the registry key to control this setting as well:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers\RightFax Fax Printer]
“Print Processor”=”RFPrint”

No popup to enter Fax Information

To have RightFax offer the Fax Information dialog box when utilizing Print-to-Fax:

Right-click the RightFax system tray icon and select ‘Configuration’

Windows 7 Printer Issue 3

Find the ‘RightFax Fax Printer’ and, if configured for Windows, change to RightFax

Windows 7 Printer Issue 4

How was that? Not too bad? Like I said earlier, give us a call if your RightFax needs go beyond this tutorial. Hey, we’re The Fax Guys and we are here to help!  If you have questions, call us now! 952-224-3340


  1. We are having majoe issue with rightfax after moving to windows 7. we receive attachment via email and create fax from them using print ot fax. after moving to windows 7 the quality of faxes is very poor and unreadable.
    can you please suggest ways to improve the quality. If we print the attachment ; scan it with black and white option, they are much better but involves two extra steps.

      Hi Nisha- Shawn (one of our awesome technical team members) is going to reach out to you. He has some ideas for you and hopefully will get you the result you are looking for! Have a great day!

  2. When you say updated drivers I will assume you mean a patch or actual install of an update vs. just changing a configuration. Does this also apply if the driver was changed on a server and pulled down?

    • Fax Girl says:

      Hi Dave- Thanks for the question! You are correct, the printer will only be affected if a patch or update is applied. Therefore, if a change was made to a print driver on a server, and was pushed down to the client level, I would expect the change to not affect the client, as there were no changes made directly to the OS. Let us know if you need anything else! Have a great day!

    Hi, I have installed the Right Fax 9.4 32 bit application in windows 7 x64. RightFax Printer is not shown/visible under Devices and Printer. Any steps to be followed. Or I need to go for 64bit Rightfax application?

    • Hello- Our Fax Guy Michael says:
      RightFax 9.4 Feature Pack 1 supports x86 and x64 versions of Windows 7.

      Prior to RightFax Client Installation, you will need to following these simple instructions:
      1. Install the HP LaserJet 4 Printer Drivers using Windows Update
      2. Disable User Account Control ¹
      3. Disable the Microsoft Windows Firewall ²

      ¹ If you cannot disable User Account Control, make sure you are logged into the client machine using a Local Administrator account. Also, use the “Run as Administrator” to launch the RightFax client setup.
      ² If you cannot disable the Windows Firewall, please make exceptions for TCP/IP ports 10520 & 10521.

      We hope that helps!

    Is there any way from keeping the rightfax client from changing the print processor. Our users can’t change the configuration

  5. Hi After going through all the steps mentioned above in the explanation I am still facing the issue. The Right Fax window do not pop up. Everytime I try to fax through my ms access applicaton a File is getting generated in “C:\ProgramData\Roaming\RightFax” with .PRT extension. When I checked file it says the I increased this memory from 663KB which was mentioned there to 5MB. Still not getting the issue fixed.Please help to solve the issue I am not able to proceed further. We have all settings exactly same as it is mentioend in our Windows 7 system.

    • Hi Padmesh-
      What version of RightFax are you using? Do you have the Print processor set to rfprint?

      If you are still having trouble, you may want to enlist the help of your RightFax Support provider. If you are not currently supported, please call us and we can get you a quote for T&M and help you out.


  6. I am having troubl with windows 7 fax, it prints out all faxes instead of going into Fax and Scan log. What can I do?

    • Hi Velinda- That sounds like a Windows 7 issue. You might want to contact Microsoft Support. Good luck to you & have a great weekend!

  7. I seen in a previous post that this was fixed in Rightfax 10.5. Is there anything that can be done on 9.4 to stop this from happening. We have thousands of user that use right fax so when this pops it causes major problems for our service desk. Any help would be greatly appreciated. We have a batch file setup to change these in order to speed up the printer change but would like to to stop it from happening all together.

    • Hi Aaron- I asked our expert RightFax team and unfortunately in version 9.4 there is nothing that can be done to stop this from happening. A possible work-around would be a login script that sets the fax printer to the settings they require via registry changes. This would prevent the issue from appearing “as much”. Just as a heads-up, as you may already know, RightFax v9.4 is nearing End-of-Life and will no longer be supported by OpenText after May 31, 2014. This might be a good time to look into upgrading, as this issue has been resolved in subsequent releases. Are you currently under a support & maintenance contract? I can certainly have one of our account managers call you to discuss The Fax Guys support options and services. Happy Holidays! (Here is a link to our support page: )

      • Thanks for all the info. I will get with our telecom team and see what our plan for this change is. We were trying to stay away from scripts if at all possible but may end up having to go this route to keep this from slaughtering our team on a regular basis.

  8. I am looking for a fix for the document quality. I am right faxing PDF binders and some of the pages are comming through clear while others are unreadable and blurry. I have changed multiple settings on both the right fax and the Adobe PRO with no success. I have Windows 7 and version 9.4 Right Fax.

    • Hi Edie-
      You can try the following, which was documented in the SR2 readme for 9.4 Fp1 SR2.

      To improve conversion quality of some PDF files, add a string value to the registry of each work server that does conversion:
      1. Open the Windows Registry Editor to the key HKEY_LOCAL_MACHINE\Software\ Rightfax\Worksrv\Worksrv#.
      (x64: HKEY_LOCAL_MACHINE\Software\ Wow6432Node\ Rightfax\Worksrv\Worksrv#)

      2. Create a new string value called GSPostScriptCode

      3. Double-click the new string value to edit it.

      4. Set the string value to:
      < < /Install { {0.90 gt { 1 } { 0 } ifelse } settransfer } >> setpagedevice

      5. Click OK.

      I hope this helps!

    We are running RightFax 10.0 Enterprise w/SR3. One of our using is unable to fax using the installed Rightfax client. She receives the error – Problem Converting Fax Body or Cover Sheet – . Her machine is Windows 7 and she also has Office 2010. Can you provide any suggestions for resolution? Note: if we use Quick fax and attach a PDF file, the fax completes but all others fail.

    Thanks in advance!

    • Hi Andy! It sounds like you do not have PDF Module installed. Is that correct? PDF Module is required if you are going to attach a PDF to a fax using FaxUtil.
      PDF Module is not required to send a PDF using the Print to Fax/RightFax Fax Printer option. If you need to purchase PDF Module, we can help you with that. Let me know if you want someone on our sales team to reach out to you. Thanks!

    • Andy-
      Another thought…A problem converting fax body or coversheets typically refers to a faulty or bad coversheet (bad code perhaps). If this is a coversheet that is used by others without issue then it could be the version of Office installed on the server. Office 2010 is supported with Rightfax 10.0 as of SR4. The correct and supported version of Office needs to be installed on the Rightfax server for server side conversion. Server side conversion happens when a user sends a fax with a Word other Office attachment.

  10. We found this and nothing worked until the following.

    I have requested the open text update knowledge base.

    Steps Tried:
    Uninstall, reboot, install – 9.4 No Change
    Repeat using 10.5 latest fr/sp- No Change

    This is what we found:
    When attempting to print from any application to right fax printer, getting error:
    A StartDocPrinter call was not issued

    It appears Adobe Flash has a file format that ends in *.SPL which is exactly the same file extension our “spool” files are trying to send. It appears Flash Player attempted to hijack this format. When going to that folder, in Explorer, Windows detected those files (that were rightfully there, where they should be in the Spool\Printers folder) as Adobe Flash files. That file format should be showing up as Uknown or not be associated with any program at all, so removing that program, then rebooting (to clear the system), then clearing the corrupted *.SPL and *.SHD files truly cleans things up.

    Step 1. Start, Control Panel, Add / Remove Programs or, Programs and Features (if they are on 7) Step 2. Locate, and remove Adobe Flash Player. Close all windows after you’re done. Reboot.
    Step 3. Open Windows Explorer. Go to Windows\System32\Spool\Printers folder and stay there.
    Step 4. Click Start, Run, type SERVICES.MSC and hit enter Step 5. Locate and stop the Spooler Service Step 6. Return to step 3, and delete all *.SPL and *.SHD files located there.
    Step 7. Return to step 5, and restart the Spooler Service
    Step 8. Verify RightFax configuration is valid, (set right printer, ensure set to RightFax and not Windows etc. Save settings)
    Step 9. Open Notepad
    Step 10. Test printing. It should now work.

  11. We, have a 9.4 sp1 SR 4 server that has the pdf conversion module and it corrupting pdf documents that the user has scanned in via omtool’s accouroute product. One of my users scanned in a 3 page document then when he tried to send it to the person it got converted into a 400+ page document.

    We found this out after his inquiry about why the fax had not gone through.

    Any ideas on why this would be happening? (I am not going to be able to upgrade the rightfax part system fyi)

    So that is a non-starter. =(

      Hi George-
      TGIF from The Fax Guys!
      I asked some of our amazing tech team “guys”:
      One “guy” said: Most likely the Rightfax Fax Printer print driver was changed to something other than HP LaserJet 4. Need to verify that the print driver for that client is set to HP Laserjet 4.

      Another “guy” said: If they are doing a Print to Fax, I would make sure the driver for the Rightfax Fax Printer is correct (HP Laserjet 4 or HP Laserjet 5200 series) If they are submitting any other way, we most likely would need to debug Conversion services and check for NativeDocControl registry keys.

      George, are you with an Authorized Support Provider? If not, let me know and we can talk to you about this further. Feel free to call 952-224-3340 another great resource is RightFax University! Check it out!
      Have a great weekend! FaxGirl

  12. Why does RightFax keep asking for my password everytime? I always choose ‘save password’. Please advise. Thanks.

  13. Hi, im from argentina and we have Right Fax 10.5. the idea is to use it as a normal printer over XenDesktop, is there a way? can you help me? thanks!

    • Hello there!
      There is a way, but it goes beyond the level of support we can offer from a blog post article, and requires a standing support contract with Opentext or an authorized reseller. Are you currently in support with OpenText or an Authorized Support Reseller? I would suggest you start there. Good luck to you!
