CaPSL Canon Printing System language, UFR ultra fast rendering...펌

CaPSL - Canon Printing System Language

CaPSL was the former standard emulation for Canon laser printers. Another name for this emulation is LIPS - Canon Laser-beam Image Processing System. The story behind CaPSL was that because Canon makes printing engines for HP, they weren't allowed to license HP PCL for their own printers. Hence the need for their own printer language. Canon lasers traditionally included CaPSL, IBM ProPrinter, ESC/P and PostScript emulations, but no PCL emulation). This part of the contract between Canon and HP has apparently expired, since nowadays Canon offers printers with PCL 4 and PCL 5 code.

A new printer recently showed up at work. There are an abundance of possible drivers for it applicable to my system (Windows 7, 64 bit) including PCL5, PCL5e, PCL6 and UFR II. I'm familiar with PCL, but not UFR II, although the ever-helpful Wikipedia told me it stands for "Ultra Fast Rendering". What (if anything) is the advantage of using the UFR II driver over one of the PCL variants? windows-7 drivers 64-bit printer share|improve this question asked Jan 25 '12 at 17:18 Richard J Foster 2592514

UFR II is the 2nd version of UFR... which stands for "Ultra Fast Renderer". In short... it's similar to PCL in concept... but alien in the actual instructions. Most commonly associated with Canon printers. PCL is more generic, common, and simple, but antiquated... UFR II is better designed, and faster, but not anywhere near as common. If you have a printer and driver that both are geared towards UFR II... use it. If not... PCL is a lot more forgiving. share|improve this answer answered Jan 25 '12 at 17:37 TheCompWiz 6,3601217

You're right that it's a Canon printer. :-) It says UFR II, and has an official driver, so I guess I'll give it a try. Thinks for confirming it was what I suspected. – Richard J Foster Jan 25 '12 at 18:52 I've been looking for a good driver for a big Canon ImageWriter 3225. Canon's Generic PCL 6 would not let me use the 11x17 paper in the bottom tray. Based on this superuser question, I tried the UFR II driver from the same download page. It is way better. It knows the exact printer model and its paper sources. It has more features too. You can to two-step printing: you can print to a preview area instead of the printer and see how it will come out, then send it off to print. You can also do some editing, like combining pages. – Kaz Jul 10 '14 at 17:14 add a comment |

No problem. We won't show you that ad again. Why didn't you like it?

Oops! I didn't mean to do this.

UFR is a proprietary, non-standard rendering engine that is functionally similar to Postscript and PCL. UFR is risky given that Canon can make it obsolete at any time based on their whims. In general, I shy away from printers that don't properly support open standards such as PostScript. Both PostScript and PCL are very fast and very well supported by the industry. In fact, PDF documents are more or less based on PostScript. UFR? You have to ask Canon nicely if they want to help you out. share|improve this answer answered Oct 19 '13 at 20:05 Garson Wills 211

UFRII print drivers are written by Canon for Canon MFDs. All Canons have the ability to print with the UFRII driver right out of the box. The PS and PCL drivers will not work unless the appropriate PS or PCL print kit is installed on the MFD. These print kits can be purchased and installed by your Canon dealer. The UFRII print driver is close to 2.5 times faster than either the PS or PCL drivers (hence the name Ultra Fast Rendering). In most printing environments, the UFRII drivers work fine. Two known examples of PS or PCL being the preferred print driver are; if an AS400 is being used as a print server (PCL) or in the case when high quality graphics is being printed (PS). share|improve this answer answered Sep 5 '13 at 7:20 user251515 111

... close to 2.5 times faster... -- using which measurement method? How can I reproduce the "2.5 times faster" figure? – ulidtko Dec 8 '14 at 11:59
