SAPSPRINT stopped printing all documents
Ensure you didn’t check the box “Save output as file”, thinking it sends a copy to a file. In fact, it redirects all printing to a file, despite the fact you are able to see in the Windows print spooler: “Printed successfully”.

The easiest way to remove Linux streams for SAP applications
su - <sidadm>
find /tmp -user $USER -name ".sapstream*" -exec rm {} +
Linux streams refer to the concept of input/output (I/O) streams in the Linux operating system. In Linux, everything is treated as a file, including input and output devices. Streams are a way to handle data flow between these files and programs. Linux streams are categorized into three types: standard input (stdin), standard output (stdout), and standard error (stderr). These streams can be redirected, piped, or manipulated using various Linux commands and utilities. Overall, streams are an essential part of the Linux I/O system and are used extensively in various Linux applications, for example, SAP Netweaver.
