Fast printing in RHEL
Hi All,
we are using RHEL 5.5 (64-Bit)for our Production server. We are using Oracle ERP Application on this . We have multiple concurrent prints which are going via OS to end user printer.( end user printers are connected to network via a usb to network converters). Right now we are using CUPS, but it is printing one by one , Our requirement is to print in parallel that too fast. there are hundereds of prints in minutes. is there a way or well know software we can use? please help. thanks Mapps |

You don't tell us what's generating these print jobs, how many pages these jobs are (typically), how many printers they're getting printed to, etc. Also...a USB to network 'converter'?? You do realize that those devices are essentially throttling the speed of a print job down to USB speed, from network speed, right?? Large documents = more transfer time = longer print queues. |
In general I agree with TB0ne, especially wrt USB/network converter (no idea what it is, but doesn't sound good). ;)
If you have multiple printers connected to the network and normal network setup on the server, I'd certainly setup a separate queue per printer. That's the normal way to do things and enables: 1. parallel output 2. ability to stop/down a given printer / printqueue without affecting any others. See these pages: http://linux.die.net/man/8/accept http://linux.die.net/man/8/reject http://linux.die.net/man/1/cancel-cups http://linux.die.net/man/8/enable http://linux.die.net/man/8/disable |

Again I'll ask: how LARGE are these pages? And you do realize that a network-to-USB 'converter', is only going to slow down your printing speed. I find it odd that your printers aren't network capable, since most of them are these days. If you have a network line going to each printer for the 'converter', why don't you plug it into the printer directly? Also, what kind of printers are these, and have you tried reading the manual on those printers?? Some printers will wait until they get the ENTIRE document, before starting to print. Some of them treat PDF's differently than other print types. Have you tried printing plain text, to see if there's any speed difference? And are you printing these in color, or black-and-white? There are LOTS of variables...you need to check/be clear on them ALL. And be aware that there is nothing magical that ANY operating system can do to make things print faster. Don't know what you mean by 'manage' queues, and you still don't say what program is generating these print jobs, or how the queue selection is getting done. |
