By default, YajHFC will send one fax per document printed to the fax printer.
You can change that behaviour to "collect" multiple documents printed to the fax printer in one fax, however (with the default Windows fax printer (Redmon or RedmonEE)).
Knowledge Base
This section contains miscellaneous information about YajHFC not included in the FAQ or other documentation.
If you did not find the answer you were looking for here, please also see the FAQ and the yajhfc-user mailing list archive.
This article contains a short example on how to automatically install YajHFC using a Windows domain logon.bat script. It has been contributed by Stefan Agethen.
Starting with version 0.5.2 the setup of YajHFC has three options for creating a fax printer. This article tries to give a short comparison to help you decide which one to choose.
Version 0.6.0 and up support adding a user comment to faxes (in both sent and received tables). If the read/unread state is saved in a database table (as described in Setting up YajHFC for small workgroups), this table needs 2 new columns where this comment can be saved.
In YajHFC, you can define custom modems. This can be useful in one of the following scenarios:
- You would like to give your modems custom names instead of the default HylaFAX names (e.g. "Company A" for ttyS0, "Company B" for ttyS1)
- You would like to make HylaFAX modem groups selectable in YajHFC.
Problem
If you are using YajHFC 0.5.2 or higher with the PDF plugin you may get the following (or a similar) exception when trying to view a received fax:
An error occured displaying the fax "faxNNNNNNNNN.tif":
