Printing slow, delayed by up to four seconds in Red Hat Enterprise Linux

Solution Verified - Updated -

Issue

  • CUPS is adding a 4 sec delay to every print job due to SNMP.
  • I was using RHEL 6.0 and upgraded to 6.1 and now every print job is delay 4 seconds because of SNMP. How can I disable this?
  • We’ve noticed that it takes 5 seconds when output arrives on the printer which is a severe showstopper.
  • We need to print a label in less than 6 seconds. How can we improve CUPS performance?
  • If we print via CUPS, the printer needs 5 seconds to start the first print. If we print some documents, the printer needs 5 seconds to start and print all the documents without further delay.

Environment

  • Red Hat Enterprise Linux (RHEL) 6, cups-1.4.2-39.el6
