Everyone,

I have been having some problems with our cups printing service for the last 4 months. I have a gateway machine that holds the printer information and is the print server. The other machines on the network use cups and cups-browsed that are set up to spool the print jobs to the gateway and then the gateway sends the data stream to the respective printers.

The problem I have is that on any of the local machines the print jobs stall. I can run lpstat lpt6 for instance which gives me the listing of the stalled print jobs, but I am not seeing error messages in the logs either on the local machine or on the gateway print server.

In doing some google searching I found that there was a problem with gh ghostscript-9.07-31.el7_6.10.x86_64 and ghostscript-cups-9.07- 31.el7_6.10.x86_64 that was apparently fixed. I am running Centos 7.9 that is fully updated with gs 9.25 on both the local machines and the gateway.

The problem is intermittent and appears with various file types pdf, ps, pcl, and txt. I have not been able to identify any specific or consistent association.

If any of you have had this problem I would sure appreciate your help.

Thanks in advance !!!! --------------------------------------------------------------------

Additional Information: When these printers become disabled the client cups machine gives me the following notice :

No destination host name supplied by cups-browsed for printer "lpt6", is cups-browsed running?

systemctl restart cups and cups-browsed does fix the problem, but this is required to do about once every 60 minutes.
