We have two serial-line cash text printers and one PCL USB printer, on which are printing from DOS application running on Linux under DOSEMU. All printers are in CUPS configured as "raw queue".
When we run on old (Fedora 9/i386 w. cups-1.3.10) configuration, data to all printers was sent almost immediately (within cca 1 sec serial printers start print).
Now after upgrade to newer distro (Fedora 14/i386 w. cups-1.4.6), we noticed significant (about further 5-6 second) delay until printing start.
Please, is there any option which can solve this issue? Or, can someone recommend any method for debugging this problem?
I tried find some info, maybe http://www.cups.org/str.php?L3744 or http://www.cups.org/str.php?L3495 reports can relate with, but not sure. Any suggestion for this bug?
