Summary :
Network printers directly defined in R/3 using access method 'U' encounter frequent "Output device not available" messages and slow printing issues. This occurs because printers attempting to simulate a host spool system face data buffering and network request handling inefficiencies, leading to timeouts and device unavailability. SAP recommends employing access methods 'L' for UNIX, 'C' for NT, or AS/400, designating printers in the host spool system as 'remote'. For HP-UX with PCL data, adding -oBSDl to rspo/host_spool/print parameter is advised. Alternatively, unadvised method 'U' can be used if printing is routed through a UNIX spooler to a remote printer.
