Hi Jim,<br>
<p>
<i>&gt; This is to report that the Umax Astra 1220S - the latest in the 1200</i><br>
<i>&gt; series - appears to work fine with SANE, with no nasty noises from the</i><br>
<i>&gt; mechanism</i><br>
Fine!<br>
<p>
<i>&gt; The resolution on xscanimage only goes up to 600dpi though</i><br>
Yes, thats the scanners optical resolution.<br>
You can scan with 600 dpi in x and with 1200 dpi in y resolution!<br>
<p>
<i>&gt; The main problems I'm having are now related to my Epson ST600 printer.</i><br>
<i>&gt; For a start I can't get the pnmtops - or any other of the netpbm tools</i><br>
<i>&gt; to work - they all want the libtiff.so.1 library, which I havn't been</i><br>
<i>&gt; able to locate. The other problem is that whilst the screen image is</i><br>
<i>&gt; true to the original, the printed image is not. I'm using the</i><br>
<i>&gt; stc600p.upp Alladin GS 5.10 filter (which works much better than the</i><br>
<i>&gt; st600 filter - which _drenches_ the paper with ink!)</i><br>
<i>&gt; </i><br>
<i>&gt; Whilst on the subject of scanning, the issues of scanner verses printer</i><br>
<i>&gt; resolution appear to be more complicated than meets the eye. Are there</i><br>
<i>&gt; any rules of thumb or is there a book `How to get the best from your</i><br>
<i>&gt; Scanner' available?</i><br>
Color correction for printers is an ugly thing. The printed picture<br>
will always look different from the original. What can be done<br>
relative simple is to use a gamma-correction for the printer.<br>
<p>
<i>&gt; Why does my scanner provide resolutions up to 9600 dpi when the default</i><br>
<i>&gt; resolution for photos seems to be 100 and OCR 300? What use is 9600 -</i><br>
<i>&gt; scanning postage stamps?</i><br>
The 9600 dpi is a lie. The driver Takes two pixels and generates some<br>
addidtional pixels between two scanned pixels.<br>
9600 dpi could be intersiting if you like to scan with a transparencey adapter<br>
from a slide or a negative.<br>
<p>
Bye<br>
Oliver<br>
