Indeed, while this is true, (a) USB scanners are still significantly more<br>
|
|
expensive than parallel port ones, (b) there are still countless thousands<br>
|
|
of parallel port scanners out there and (c) unless their exists some<br>
|
|
sort of USB scanner command set that manufactures actually stick too, are<br>
|
|
they any more likely to give us the protocols for USB scanners than<br>
|
|
parallel ones?<br>
|
|
<p>
|
|
Just my experience though, a scanner will turn any fast multi-user,<br>
|
|
multi-tasking machine to a single-task machine SCSI or otherwise.<br>
