MR vs. MMR vs. I would disagree with this generally. Normally the benefit that you get from MMR compression support by far makes up for the cost of enabling ECM on the modem retransmits, etc.

MR vs. MMR vs. I would disagree with this generally. Normally the benefit that you get from MMR compression support by far makes up for the cost of enabling ECM on the modem retransmits, etc. If your transmission paths are truly clean then retransmissions should be few, and when no retransmissions occur then ECM protocol does not take much more time than non-ECM.
One uses Floyd-Steinberg dithering from libtiff, and the other uses a stochastic filter that Ghostscript has available itself. Look at the difference that these dithering approaches make. Also understand that the finer dithering does dramatically increase the size of the data. So HylaFAX traditionally has used that generalization to make format selection decisions. However, as I pointed out in the Cluecon presentation, there are some cases where this does not hold true, where 2-D encoding is ineffective where black-to-white-to-black alternations occur frequently in a horizontal column - such as when a photographic image is dithered to monochrome.
JBIG is still preferred over all formats as it only performs poorly in extremely rare contrived scenarios. Give some examples of what you mean. Thanks, Lee. As I found out, there are some variables which influence this and could be tuned : - resolution: 98 vs.
It is logical that 98 lpi brings less data to send, thus less time spent on page transmission - however this is a quality compromise. Is there any measurement to decide which is the best encoding method to send a given tiff file? What I mean is for example this could be useless idea : Encode a raw tiff with different methods and from the final tiff file size decide which encoding is better MH or MR or MMR.
I would like to ask also if there are some modem settings which could lower the transmission time for successful fax delivery and for failed calls to detect that there is no fax as fast as it can. Thank you in advance!
Unfortunately After that you have to look at the image files that you submit
HylaFAX Community Edition
It has its own fax-server software, but because it uses an email-to-fax method, the RelayFax client software may be used in conjunction with a HylaFAX server using sendmail and procmail. See RelayFax for more information. Cypheus from Bodo Noering is for Windows. It is quite versatile, feature-rich, and has been well-supported. Cypheus serves well as a fax administrator utility.
Winprint HylaFAX Reloaded
Install the hylafax-server package apt-get install hylafax-server Make sure your modem is connected. Fax sending and receiving is very time critical. There has been numerous cases where a setup is fine but the virtual environment causes failures that are hard to diagnose. Initial Configuration run the faxsetup utility to begin configuring hylafax. Assuming there were no errors, you will see a menu like the following: HylaFAX configuration parameters are:  Init script starts faxq: yes  Init script starts hfaxd yes  Start old protocol: no  Start paging protocol: no Are these ok [yes]? Restarting HylaFAX server processes.
It is highly recommended to use one of those programs for any modern Windows systems. Once installed, you can print to a HylaFAX Server from any application, and it will pop up a simple dialog box, allowing you to enter the destination FAX number.

DLL files and registers the monitor with the system.
