Question about HP PSC 2210 All-In-One InkJet Printer
Lately been trying to scan my transcript, but all turn out to be in bad shape. However I made a copy directly and it turn out to be very well! Can someone kindly advise what can do to improve the quality of the scan?
Use Higher DPI settings on scanned text for OCR, than for copying,
in copies the printer does not know what it is looking at
in OCR machine logic has to determine what each shape is,
and translate it to a character.
at small DPI each letter may be too few dots high to easily differentiate between similar letters
compare the quality of 10pt text from a 9pin dot matrix printer, to 10pt text from a 1200dpi linotype or laser printer
higher dpi is easier to read, it is easier to OCR, the scan may take longer, the error rate needing correction will likewise be lower
A long time ago was scanning Telecom Australia paper bills into the first online service they had
My workstation, scanned at 1200 dpi, had no retyping
others were using 300 dpi then retyping all the errors
was paid by the page
I made way more money
even though the scans were about 5 times slower
