Printing with Chromium https://github.com/Evidlo/remarkable_printer gives an error.

Steps to reproduce

1. Print to reMarkable in Chromium (Print to PDF and use pdfinfo to verify that your browser creates PDF with PDF version 1.4)

reMarkable: ~/ ./printer.arm -host 0.0.0.0 -port 9100 -debug -restart  
Saving PDF to /home/root/.local/share/remarkable/xochitl/10376b64-c106-43d2-a1af-3cbfbc702c94.pdf
[%PDF-1.4
]
[PDF begin]
[Invalid PDF]

1. Save to PDF in Chromium
2. Convert PDF to PDF version 1.6 $ gs -q -sDEVICE=pdfwrite -dCompatibilityLevel=1.6 -o Evidlo_remarkable_printer_\ Native\ printing\ to\ reMarkable_V1.6.pdf Evidlo_remarkable_printer_\ Native\ printing\ to\ reMarkable_.pdf
3. Send with lp

This should be fixed with the latest release.

The problem wasn't actually the version number, but the fact that the code assumed the last line of the PDF ends with a newline, which Chrome doesn't do.

Thanks for the quick reply and fix! It now works as expected.

Thanks again for creating this software!
