Hi,

The Samsung driver is working great for me, however, there is one big caveat which I encountered when printing a large PDF document: Turns out that the page content gets shifted more and more. The first page is fine, but on subsequent pages, the content gets shifted to the upper right. This increases from page to page and is very obvious on the last page of a 20-pages document. I'm attaching a photo that illustrates the problem.

My printer is a Samsung CLP-510N, connected via Ethernet to an Ubuntu 20.04 server running CUPS 2.3.1. It is shared, so macOS and iOS devices can print via Bonjour/AirPrint. I have installed suld-driver-4.00.39.

I encountered this problem when printing from Preview on macOS Catalina. I didn't get a chance to try printing from other clients, such as Windows, but can arrange that if it helps to narrow down the problem.

Interestingly, this doesn't happen if I print the pages individually from the same PDF.

Any advise?

Thanks,
Aaron

Hi,

I would like to force all print jobs sent to my Samsung CLP-510N to monochrome, even when the client explicitly requests color mode.

The background is that we don't want to replace the colored cartridges anymore and use the printer as a monochrome printer only. Therefore, the colored cartridges are always empty, and a user who doesn't know this will get an unexpected result.

I have already set color mode to "Grayscale" in the default options, however, iOS devices don't seem to adhere to this default and try to color print anyway.

Any idea how I can achieve this?

Hi,

First of all, thanks for keeping this repository up to date! I saw there were plans to shut it down last year, and I'm glad to hear that you chose to let it live for a few more years.

So here is my problem:

I have installed suld-driver-4.00.39 (maximum version for my CLP-510N) on a fresh Ubuntu 20.04 system. This ships with CUPS 2.3.1. The printer is connected via network through LDP (connection: lpd://192.168.178.28/queue).

When I try to print, the job fails with stopped "Filter failed".

I believe this is the relevant portion of the debug log:

So two things that seem fishy:

• [...] rastertosamsungsplc) stopped with status 127 (File too large)
• error while loading shared libraries: libcupsimage.so.2: cannot open shared object file: No such file or directory

I'm adding the full debug log as an attachment (limited to lines containing "[Job").

Any idea how I can fix this? Is my Ubuntu/CUPS too new?

Thanks,
Aaron
