Is OS X Preview the biggest feature in Tiger?

Spotlight is buggy, but it is pretty good. Nonetheles, OS X Preview may be a serious contender for the most valuable component of OS X. Annotating a PDF, or completing a PDF form, usually requires the $$ Adobe Acrobat application. As of Tiger, "Preview" (awful name) does this and more:
Annotations
View and create annotations to a PDF document from Preview.
DNG File Format Support
Open files in the new Adobe DNG (Digital Negative) format.
Forms
Fill out and print PDF forms.
Image Keywords
Add, remove and modify keywords for images.
JPEG2000 Support
Open files in the next generation JPEG2000 image format.
OpenEXR Image Format
Open images stored in OpenEXR file format.
RAW Camera Image Support
Open images in the RAW file format used by Canon, Nikon and other models.
Image Correction
Adjust colors, exposure and more, thanks to Core Image.
PDF 1.5 Document Compatibility
Take advantage of PDF 1.5.
Screen Capture
Capture screen shots and more using features previously available in the Grab application.
Slide Show
View an elegant full screen slideshow of images opened in Preview.
I tried the slideshow! Neat, but I couldn't figure out how to stop it ...

Darik's Boot and Nuke: sterilize an old computer prior to donation or sale

I've found a home for an old machine, but how do I wipe the drives? I'd read a while back about this utility, and Google found it for me. I'll report on how well it works.
Darik's Boot and Nuke

Darik's Boot and Nuke ('DBAN') is a self-contained boot floppy that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.
I assume by "emergency" destruction they're referring to a scenario I'd rather not think about too much.

Update 10/10: Seemed to work perfectly. Downloaded the zip, ran the executable that creates the floppy, rebooted, hit enter, selected drives to wipe, accepted the default (medium security). Took about two hours to wipe two drives simultaneously. Of course I don't know how good the erasure is, but I'm betting it's pretty good. I trashed the diskette, I've no need to keep a 'loaded diskette' in the house. I give away a machine every few years.

kw: Linux, diskette, disk, wipe, clean, purge

Google's RSS reader - no threat to bloglines

Google has a web basedRSS/Atom Reader. I imported my bloglines OPML file. I don't get it. It feels like a terribly clumsy and ugly news reader.

Brother MFC-7820N: my cumulative review and experience

Update 2/10/06: Please see an excellent comment below posted @ 2/9/06. It appears Brother has fixed the Bonjour bug in its newest releases, and the Brother support site now mentions the bug with the XP SP2 firewall. (The device can't communicate with the scanner software, and produces a misleading error message about a problem with the ethernet cable.)

I had complained previously about a "bug" where the fax was picking up incoming calls despite being disabled. It turned the home security system we "inherited" has a hidden modem used by the security company. Under certain conditions our home security system modem answers the phone! It has nothing to do with the MFC.

Brother was slow to pay my rebate, it took over 8 weeks. After months of use I do think this device actually works better with OS X than with XP SP2; but I expect the newest release will be a very good buy. Remember to deal with the XP SP2 firewall problem though.

--

I just bought a Brother MFC-7820N 5-in-1 Network Monochrome Laser Multifunction Center from buy.com. I think it might turn out to be a good device, but there's a very nasty bug that prevents the ethernet interface from working with a Mac. It's fixable if you know the magic trick. From my Amazon review:
OS X - rather nasty setup problems, October 7, 2005

I have both XP and OS X Tiger (10.4.2) machines on my home LAN. I installed the brother to both machines. In both cases I downloaded the very latest software patches from Brother's site.

The XP install went rather well, but I realized too late the downloaded drivers didn't include the OCR software. Annoying. I'd recommend doing the CD install first then downloading and updating from the downloads.

If you install XP SP2 you install a firewall. The firewall blocks the scan to machine capability. I have disabled it for now. If you don't disable the firewall, you get a spurious 'check cable' message.

The OS X install was another story. Actually, this is pretty outrageous. Bonjour (was Rendezvous) install didn't work at all. The printer didn't appear in my network display (Printer Setup Utility, Print Center).

It took about a half hour of late night hacking and googling and amazon review reading to figure out that Brother misconfigured the printer. They didn't define something called a 'mDNS' name. Without this name Bonjour/Rendezvous doesn't work. [Update: turns out the place I vaguely remembered this from was a quick posting I'd put up 6 days before I wrote this. If you lived my life you'd understand.]

How do you define this? Well, to make a long story short, dig through the CD and find the help file called ALL_EngNet.pdf. Chapter 7 describes the browser interface. Use your browser and the IP address of the brother to get the web UI. You need the admin un of 'admin' and password of 'access'. (This is publicly downloadable, not secret, you can chang pw.) Then from the home page click Network Configuration then click on configuremDNS, then name the machine (BrotherMFC works). Now you can add it as a printer.

It's astounding that Brother doesn't even mention this on their web site help files. It's a pretty darned serious bug.
A few other comments on the problematic Mac software:
  1. If you install the default Brother Control Center software, you have to configure the printer for every user (one time on initial login). Each time you get to choose the scan to machine option. If that works at all it's a system level option, so this doesn't make sense. (In fact it seems to work though ...)
  2. The PC gets a full configuration utility, the Mac uses a web tool (works fine) that is documented in an exceedingly obscure place. As of October 2008 the OS X downloaded utilities does install a "remote Setup" application that is supposed to do the same thing as the web UI. It starts but crashes after about 10 seconds. I run as a non-admin user, I didn't test it as an admin user.
  3. The PC gets a well known OCR package, the Mac gets something called Presto (OCR on the Mac is not a big market).
  4. I took a different approach with my 10.3.9 iBook. I downloaded just the CUPS and PPD drivers from the 7820N support site. I installed only those on the iBook. I was able to quickly see the Brother printer and the drivers installed seamlessly. I didn't have to deal with the 'Brother Control Center' complexity and odd behavior. With 10.5 you don't need the printer drivers, but you still need to install TWAIN drivers for scanning: I re-enable the 'scan to server' button with OS X 10.5.
  5. To clarify (someone asked): I am able to print, scan and send fax from my iMac. I haven't tried receiving faxes on the iMac. I also was able to get the scan-to-Machine button to work from the MFC, I was surprised that worked.
  6. The web interface includes an interesting report page: http://10.0.1.2/etc/mnt_info.html?kind=item (on my network). From that I see that I've printed 6,460 pages and that my drum is at 58% of its lifespan. I've changed toner 3 times (I'm about out of my 3rd, so I'm getting an average of 2,100 pages per cartridge. Of course the 1st cartridge is always a "starter" cartridge, so that understates the full cartridge performance. I was amazed to see I'd scanned over 1,000 pages. I've had 25 paper jams, most recently (see update, below).
The documentation error is particularly annoying -- they provide quite a bit of documentation, they should have referenced the Mac web configuration in the install document.

A few hardware notes (updated as I learn more):
  1. It's very noisy when printing and starting up, but it quickly goes into sleep mode. In sleep mode it's louder than my (very quiet) iMac, but it's across the room from me.
  2. It comes with a 'starter' toner kit good for 1500 pages, rather than a full 2500 page TN-350 toner cartridge. Kind of a sneaky move but common in the printer industry. The cartridge lasted about 6 months with light use. (see update 11/16/08 below about print life extension trick). Brother does not recycle used cartridges; by contrast HP used to. Changing the cartridge is a bit odd. You pull out a module that has the cartridge and the print head, swap the cartridge, clean the print head (don't touch it, read the directions!), and reinsert both. If Brother were to stop making the TN-350 cartridge the MFC-7820N would be worthless; when buying a printer it's always worth seeing how hard it is to find a replacement cartridge. It's a good sign if it works with many different machines. This one fits eight Brother printers and one Brother fax machine.
  3. Compared to the 11 yo LaserWriter Select 360 it feels really flimsy. Of course the 360 was an utter tank. I finally gave up on it because it was getting hard to find high quality toner cartridges, and because the 360 had become the noisiest fan in my office.
  4. In limited testing I'm pleased with the sheet feeder and photocopying.
  5. I finally realized that the client side Mac software interface is a small icon in the top bar. Once I defined a custom B&W scan that takes a set of pages and scans them with great speed into a multi-page PDF in a preset folder ... well, I'm really warming to to this device. To my amazement the button on the MFC will scan to a folder on my Mac (setup using the 2.1.3 Brother control center).
  6. The fax send seems to work very well both from the main machine and from OS X (print to fax -- not sure the address book works though - Mac OS X Hints references a bug with manually entered fax numbers).
  7. 10/12/05: I was asked about scan speed. I scanned 10 pages 300 dpi B&W in 90 seconds, so about 9 seconds a page. Good for my purposes, I think the new Fujitsu SnapScan sounds pretty impressive for persons needing heavier duty document scanning. I do B&W for document scanning because it compresses exceedingly well. I'd do color or gray scale document scans if the vendors supported JPEG2000 compression within PDF. (Adobe supports this in the latest version of Acrobat).
Update 11/8/05: Pierre-Etienne has submitted this related tip for Brother MFC-420CN: (Incidentally, the undocumented telnet capability without a password is a bad security practice.)
Thanks for your postings on the MFC configuration problem. It pointed me to the right problem (no mdns name) but not the right solution since my Brother MFC-420CN model doesn't have a web interface.

However, digging deeper I found that all Brother MFC Network printers have a telnet interface!

Just telnet to the ip address, enter password (mine wasn't "access" but was nothing at all... just entering nothing as a passwd worked). Now:

set mdns enable
set mdns name xxx
show mdns

Wait a few minutes for things to refresh and the deed is done.
Update 1/24/06 - the "check cable' bug. (2/10/06 - yes, it's the firewall)

symptoms:
  • pushed the scan button and the printer LCD panel replied "check cable".
  • Cables, hubs, etc are fine.
  • If push scan button and select machine name in drop down list for scan to file, Brother is unable to connect to PC
  • Power cycling etc doesn't make problem go away.
cause:
Update 6/12/06:

I ran into a problem where I couldn't set the print resolution in OS X. The radio button control was malfunctioning -- every button was set. I checked the support page (cryptic location) and found a firmware update and one page with instructions for a CUPS driver, another with instructions for a BR-Script driver.

The firmware update took a long time to run, but it completed without a problem. Those things scare me.

It turns out that both driver pages download the same installer: brxubprt11c.dmg. This in turn contains a mis-spelled package: BrotherPriterDrivers. (Broken english litters all of the Brother updates.)

Ignore the directions. If you've followed the above instructions, or installed the firmware update, Bonjour discovery should work. You can choose to install either the CUPS or BR-Script driver. I had good luck with the CUPS driver so I stayed with that. The bug, btw, was fixed.
  • The name of CUPS driver is "model name + CUPS v1.1"
  • The name of BR-Script driver is "model name + BR-Script 3".
Update 12/28/06: Firewalls and Ports

OS X Firewall seems to manage the MFC-7820N connection well enough, but on XP Firewall services (Windows Live One, for example) break functionality with obscure error messages. Brother's website has a ridiculous technote on this that advises users to disable their Firewall software. As if XP wasn't dangerous enough to use in the first place. The end of the tech note does, grudgingly, specify the UDP ports that need to be open - Port 54925 and Port 137.

Update 3/17/07: OS X Image Capture will control this scanner

I don't know if this is new with 10.4.9, but I discovered today that OS X Image Capture will drive the scanner. In Image capture it's Devices:Browse Devices. You'll see the Brother. Click on use Twain. Now you can scan from it into Image Capture. Nice!

BTW, I've been using this machine for over a year now, and it's really worked well. It's complex and the corporate support is pretty flimsy, but it's impressive.

Update 5/20/07: With OS X 10.4.9 if network configuration changes may need to power cycle the MFC and transiently disable the OS X firewall to reestablish connectivity.

Aren't networks wonderful? They're bad enough all by themselves, but adding in a firewall makes things worse. Then add multi-user workstations ...

Advanced firewalls notify users of failed attempts via the GUI, but the base XP and 10.4 firewalls don't. In any case today the MFC couldn't scan to my iMac and my iMac couldn't drive the scanner. (Open control center, click the file, try a scan, get a "can't communicate" message.) Here's what I did:
  • power cycle MFC
  • turn off OS X firewall
  • use the Control Center scan to file to re-establish a connection (scan anything, doesn't matter what)
  • re-enable the firewall
  • now everything works.
You'd think I could use the OS X firewall logging (see advanced options in the firewall control dialog) to figure out what's failing, but there's a bug in 10.4. You need to be an admin to view that log and 10.4.9 doesn't provide the GUI 'escalate to admin' option. That's a bug.

Update 7/10/07: I've tracked down an old, intermittently annoying, bug. I'd found over the years that the scanner would stop printing; I had to power cycle it to fix the problem. Print jobs hang at 16% or so from OS X. Today I realized this happens after faxing, which we rarely do. If I buy another "all in one" I'll try to remember to test for post-fax functionality.

Update 10/19/08: When I installed 10.5 it installed its own printer driver. Seems to work. On the other hand, the sheet feeder is jamming. I'll try cleaning things out, but I suspect it's come to the end of its life after 3 years of mild use. I mourn for my Apple LaserWriter Select 360; after ten years I had to get rid of it because nobody made toner for it any more. Incidentally, I found a fix for problem of the printer reporting a paper jam that cannot be cleared. Another article describes my problem but doesn't have a fix.

Update 10/28/08: I re-enable the 'scan to server' button with OS X 10.5.

Update 11/6/08: The printer has a pretty strict standard for toner levels. When the toner declines past a set level it stops printing. Today I went to order a new cartridge and found, at the very top of the reviews, this superb tip:
I get 800 to 1100 extra copies from each cartridge.

After the "Toner Life End" message appears, it refuses to print even one more copy.

Remove the cartridge and find 2 clear plastic port holes, one on each side. The printer shines a light through these to decide when to shut you off...

Cover one or both windows with a small piece of masking tape. I get about 3400 copies per cartridge instead of 2400....

... There is also another fix for the toner end of life error message that supposedly works - Open the front cover, not touching the drum, and press options. Press option 2 - to not replace drum ...
I used the masking tape fix.

I'll order a new cartridge, but there's no rush now. I'm amazed, by the way, to find that Amazon still sells this exact printer. I'm not used to modern products with this long a life cycle.

Update 12/27/09: I am printing to this from 10.6.2. I didn't install any drivers. More interesting, Snow Leopard's Image Capture is pulling scans off the device!

Update 1/11/10: I was having pretty severe paper jams, so I figured it was finished. The problem resolved in testing. Turns out, like me, it's saggy. On a flat surface it's good, but I had it on a short bookcase that didn't support it properly. It needs support in its dotage.

Update 1/23/10: If you create an managed account with limited application access, you'll get a series of annoying error messages from the Brother software. The messages refer to applications found in Library\Printers\Brother\Utilities\Server such as LOGINserver, NETserver and USBserver as well as "Control Center". These apps, incidentally, do not show up as login items. There may be a way to enable them in Parental Controls, but I did it the hard way. I kept logging in the managed account and entering "Allow Always" with my admin password until they finally stopped appearing. It took four logins.
