Dear SCO Customer, Support Level Supplement (SLS) OSS650A, the LPD Supplement for OpenServer 5, addresses the following problem: Network printers installed on OpenServer 5 using the LPD protocol are intermittently dropping jobs. There are no errors generated. This seems to occur when multiple requests are sent to the printer at once. There is an issue with LPD file locking that causes the LPD /usr/lpd/remote/lp program to ignore a job if it comes too quickly before the next job request. SLS OSS650A contains these files: /usr/lpd/remote/lp Software Notes and Recommendations ---------------------------------- SLS OSS650A can be installed on: SCO OpenServer Release 5.0.6 with Release Supplement 506A (rs506a) SCO OpenServer Release 5.0.5 with Release Supplement 505A (rs505a) and SLS OSS497C It is also known to install on SCO OpenServer Release 5.0.2, and SCO OpenServer Release 5.0.4 with Release Supplement 504C (rs504c).
