German translation of the HP 48S and HP 48G user guide
Hi,

I am looking for the German translation of the HP 48S and HP 48G user guide. On the HP website or on the HP Museum USB stick is only the English version. Does anyone know if the scans are available in German?

Thank you and best regards
Joerg

Thanks, but this user guide is based on the HP 49g+/HP 50g user guide. I'm looking for the nice and beautiful HP 48S and HP 48G user guides from the 1990's (e.g. http://h10032.www1.hp.com/ctg/Manual/c00442262.pdf or http://h10032.www1.hp.com/ctg/Manual/bpia5212.pdf).

RE: German translation of the HP 48S and HP 48G user guide
Hi,
i have now scanned the two German manuals for HP48S and HP48G in 300 dpi. But the PDF files are very large, 380 MB and 288 MB. Does anyone have a tip or experience, how can I shrink the PDF files? The books in English have a size of about 40 MB and 35 MB and can actually be read well.

Thanks and best regards
Joerg

I use Acrobat XI Pro. Happy to give 'em a go IF I had the two files.

300dpi is way overkill for this kind of application. I'd scan at 100dpi instead. That will reduce your file size nearly ten-fold.

The main reason for selecting 300dpi would not be for text recognition (as in this case) but for retention of inline image quality. Otherwise, if you don't have to keep the images (and don't care about them) then 100dpi makes far more sense; some of the text recognition programs I've used suggest this.

Although much, much less common than PDF, DjVu format is better suited for scanned documents.

Not with printed material. All you'll get by scanning printed documents at that resolution is a faithful reproduction of the print screen and a load of moirage.

Only with poor quality downsampling algorithms. As long as your image viewer uses something like the Lanczos algorithm (or better) it's not a major problem. And with higher DPI screens becoming more popular, it is becoming less and less of a concern. I'm all in favor of scanning at 300 dpi.

I agree. It drives me batty to finally locate a PDF of some scarce old manual and then find that somebody scanned at it 100 dpi. In the interest of squeezing the file, the images are often worthless. That happens all the time with slide rule manuals, where it REALLY is important to see those fine lines in the drawings :-) It astounds me that people put all that effort in and then don't (apparently) themselves look through the file afterward to see that it's utility is severely compromised by their byte-frugality.

I understand for things that were scanned in the 1990s, but storage today is cheap. Don't waste your time scanning archive material at such low resolution.

It's also worth noting that color depth (if any) is also a significant factor here. Does this scan need to be in color? If so, at what depth?

Most scans I make for "information transfer" (as opposed to photographic/image quality) are saved in 1 bit/pixel 300dpi (sometimes 600dpi for documents where more detail is required). If there's any gradient graphic content, I'll use dithering during the final conversion.

... Thanks all for the answers. I still found the tool https://www.pdfcompressor.net/index.html, which achieves good results.

SlideRule, I still have your email address from back then. Is this still valid?

Hi SlideRule,

sorry for delay, great job. But the best are the bookmarks. I will provide the manuals for the HP Museum Document Set.

Kind Regards and thanks again
