Scanlite is simple and easy to use. Is there an add on to export the scan as a PDF? Also I sometimes would like to print directly from the scanner. I’m not doing color graphics but rather documents.
AFAIK no. I scan pages in and let Scanlite number them as it saves them to a folder. Then I open a new document in LibreOffice and import each image followed by a Manual Page Break after which I export to PDF and close the LibreOffice document without saving. You may think it is a bit tedious but I have found it takes slightly less time than the dedicated PDF producer I used to use.
Note: GScan2pdf is supposed to be able to do this but, the last couple of times I tried to download it, it had a missing dependency.

I think that xsane can scan to pdf, but my scanner is currently powered
off and xsane refuses to start, so that I can check.

I use simple-scan. It allows this and can concatenate multiple scanned documents into a single PDF if desired.

xsane does indeed scan to PDF.

I found that simple-scan creates relatively large sized PDFs, which was a problem for me because it significantly increased the amount of space I needed for the archive I was creating. But, if file size is not a problem, simple-scan is a good solution.

IMO, pdf is an improper format for scanned documents; instead, you
should be using djvu.
What pdf basically does is integrate images, I think as jpeg, in a
document with pages. The size depends on how those images are actually
created, handled and inserted.
One strategy would be to create very compressed jpegs, and insert them
as they are, unchanged. But as the PDFs are generated by a program, and
you do not control the steps, you get what you get.
DjVu, on the other hand, was designed as a multipage format for storing
and distributing scanned documents. But generating DjVu is not trivial,
and support is limited.
(you can also annotate pdfs with some readers).
Even when I’m required to generate pdfs, I scan to jpeg, and then I
generate the pdf with a script that I control, adjusting to get the
quality and size I require, without scanning again the whole batch.

Yes, I do experience that, and my solution is simple. I use Okular to view and print the document to file (PDF again). In the process, the resulting .pdf is a significantly smaller size with no obvious change in quality.
Certain standards permit this but normally it integrates an image into a compressed image stream: see the Raster images section of PDF - Wikipedia.

Anyway, the method described in that section are still standard image
compression: fax, jbig2, jpeg 2000, and some others.

I realize this is an incredibly old post, but came here for this info today and found something that may be useful to others. I used scanlite to get the images, then labled them with an incremental number such as image1.png, image2.png, etc…
then used command line: convert image*.png document.pdf
worked great, then can use okular if needed to adjust filesize, but was not needed in my case
