Clean files up on PDF receive fail

[ershov]

After printing, systemctl says that the service is failed.

I ran /home/root/bin/printer.arm -debug via ssh and printed a document. After a lot of (supposedly, postscript) output, it said Couldn't find PDF start and exited with error code 130.

It creates zero-sized files in /home/root/.local/share/remarkable/xochitl.

I need to see the log with -debug on to know what the content looks like. My guess is that you're sending Postscript data instead of PDF data. This tool only supports PDF data (starts with %PDF-X.Y).

Couldn't find PDF start

This is definitely PostScript, not PDF. Did I install printer incorrectly?

Also, when adding a printer, it fails multiple times.

Once, with empty input, another time, with this:

I think the tool needs first to make sure there is something to save, then create a file for that.

Here's an example of full debug output: printer-debug-out.txt

[Evidlo]

Check release v12.0.1

It cleans up the PDF file if the start/end can't be found.

[ershov]

Hmm I think, my main concern is that it doesn't work. Not cleaning up failed files is a side effect of it.

As you said in your 2nd comment, the problem is that your computer is sending Postscript instead of PDF data. Delete your computer's reMarkable printer configuration and set it up again. The driver you choose during setup is important.

[ershov]

Hey this is MacOS, I don't have control over what it sends. I configured the printer in a standard way and that's what it does. Is there any way to make it send PDFs?

[Evidlo]

You have to follow the instructions in the readme. If you didn't set the protocol it won't work

Hey I did follow the instructions. "HP Jetdirect" is the default and there's not a lot of options available: AirPrint, IPP, LPD, HP Direct Jet. It's hard to misconfigure it.

[Evidlo]

Maybe you can try directly through the CUPS web interface:

If you don't see that option, then OSX might have removed it. Have you also tried the easy install method?
