flexfax: Fax Quality Not Consistent

[cn.liu@ptc.com.tw (CN Liu)]

Hi! All,

I need your help to improve the fax quality.

The server: Hylafax 4.0p11 under Linux 2.0.32 with gcc 2.7.22 and ZyXEL
U-1496E. gs3.33,fonts-3.33,jpeg-5a are used.

The client software is Whfc 0.5 running in Windows 95 Traditional Chinese
version (4.00.950). The client printer driver is HP 4/4M Postscript.

The qualities of the fax differ from sources to sources: documents of
Word97,IE3.02, and Powerpoint97 are fair but documents of EUDORA 1.5.4,
Excel97 are poor. The term "pool" means that the characters are too light
(some pixels are missing). Enlarging the font size does not improve the fax
quality because the missing pixels in the documents of larger font size may
appear in those document of smaller font size, and vice versa. 

The "very light" problem seems to always happen to specific characters. Take
Eudora email as an example, the "dot" on the top of character "i" is too
vague to be seen, and "m" looks like "n". Although other characters in the
email are readable, they are not heavily printed enough, either. 

Excel table lines and borders are fairely faxed but characters are not (they
are too light).

Thank you all in advance for suggestions!
