OVERVIEW:  You know that old saying about “Things going in threes?”  Well that saying is not just all about gloom and doom. In Samsung’s case, the best things come in threes. The latest in Samsung’s ML-3560 trilogy contains the best of the first two, and adds 2-sided printing: Meet the Samsung ML-3561ND.

PROS:
The “D” in ML-3561ND is for “duplexing”. Two-sided printing is an economic and environmentally friendly way to save on paper. This feature, along with the options to print pages either Long Edge or Short Edge, enables the printer to be used for desktop publishing of bound booklets, catalogs, and calendars.

The ML-3561ND prints fast--be it single-sided or 2-sided. It does take almost 50 seconds for the printer to warm up from a cold boot, but once it’s up this laser starts chugging letter-size prints at 35 pages per minute. Even duplex printing of 19 double-sided pages a minute, the ML-3561ND is one of the fastest of the ML series. There’s an additional 9 second delay between print jobs and high-resolution printing.

This printer has some serious paper capacity. The ML-3561ND comes standard with a 500-sheet cassette tray, capable of holding an entire ream of letter or legal-size paper. The flip-door reveals a 100-sheet multi-purpose tray that can handle transparencies, labels, post cards, envelopes, 3” x 5” postcards up to 8½” x 14” legal paper of various bond weights.

At 1200 x 1200 dpi resolution, the ML-3561ND keeps text sharp--even at 6-point font sizes--and does a decent job with graphics. To keep from consuming too much toner, the printer has a 600 dpi resolution with a text-enhance or image-enhance switch.  The Toner Save feature allows for a 40% toner life increase while keeping images clear and readable.

The “N” in ML-3561ND is for “network is built in”.  The Ethernet 10/100 Base TX interface makes it ready to support networked computers in an office, department, or a classroom. You can choose between Parallel, USB, or Ethernet connectivity. So, no matter how old or new your computer is, the ML-3561ND can handle it.

This laser printer packs 32MB of memory. The ML-3561ND can easily handle workloads from multiple computer requests. An additional DIMM RAM slot is available to expand printer memory up to 288MB.

Understanding the printing needs of today’s businesses in providing support for the major software applications, Samsung has installed a full set for print emulators that should satisfy the most diverse office. Emulators include PostScript3, HP PCL6, IBM ProPrinter, and EPSON.

The control panel on the ML-3561ND has a multi-line LCD Display, plus buttons that make manual control of the printer relatively intuitive. Through the control panel, printer information, configuration, emulation, and network settings can be done. Administrators can also perform these changes remotely with Samsung’s SyncThru web application.

If you think this printer has it all, there are still more options you can add to the ML-3561ND. To reduce workload on the printer’s RAM, print jobs can be queued into a 40GB hard disk module. For laptop printing support, Samsung offers a wireless LAN card that supports a, b, and g-band standards. A second paper tray can be stacked under the ML-3561ND to provide 500 sheets of additional paper capacity.

CONS:
This is not a small, compact printer. At 40 pounds and a footprint that takes up just over a 2 square-foot area, the ML-3561ND will need a permanent and a sturdy place to stay.

The printer produces 55dB of sound printing, idling at 35 dB. To give you an idea of what that means: 60 decibels is the level of typical conversations and 30 decibels is a quiet office. You probably don’t want to have this network printer stationed in a conference room printing when a meeting is in progress. But when placed in the copy room or in the middle of a busy office floor, the noise is barely noticeable.

INK / TONER NEEDS:
The ML-3561ND’s toner and drum are integrated in a single cartridge, making it easy to maintain. Right out the box, the printer comes with the standard size toner, able to print up to 6,000 pages.  A 12,000 high-capacity toner option is also available to double the time between toner replacements. This is great for a department or an office with heavy printing demands.

SOFTWARE:
The ML-3561ND has one of the better software packages. Not only does it have the basic printing properties for Mac and Linux, but for Windows users there’s an advanced printing section that allows for booklet printing, creating a large poster mosaics, and watermarks.

The drivers also enable 64-bit and Microsoft Server operating systems to be able to use the ML-3561ND. This may be considered a no-brainer, but there are printers with software that absolutely will not install on Server 2003 & 2008.

To make network printer configurations and notifications easy, Samsung’s SyncThru Web Service allows printer changes to be made using your IE, Safari, or Firefox browser. The software is not part of the CD and has to be downloaded from Samsung’s web site.

The ML-3561ND is a serious printer for serious business workloads, with the ability for additional expansion for future longevity. – Mel Myers

OVERVIEW:  In that traditional American sprit of entrepreneurship, more and more people today are setting up their own small businesses: be it in a leased office, in the garage, or in a spare bedroom. And with every small business, there is a need to keep expenses down while you’re starting up. The older sibling to the ML-2510, the Samsung ML-2570 offers higher resolutions for sharper B&W prints, more print memory, and decent paper capacity, all packaged in a neat, compact size.

PROS:
This monochrome laser (that’s what the “ML” in ML-2570 stands for), occupies an area just over one square foot on your desk or shelf.

This laser can accept a range of paper weights from 16 to 43# for both paper trays, giving its owner a wider range of paper choices than some other printer brands would allow. However, for manual 2-sided printing (you’re flipping the paper over yourself) use 20-24# weight paper to save yourself some grief.

When you flip open the door on the front of the ML-2570, it reveals the 250-sheet paper tray. The single-sheet manual feeder is above the main paper tray, for printing labels, cards, and transparencies (and make sure to use transparencies that are “laser printer safe”). The main tray can handle a variety of sizes: from postcard (3” x 5”) to legal (8 ½” x 11”). The ML-2570’s larger paper and toner capacity makes it ideal for people who rely on printing throughout the day or an office having multiple computers sharing a single printer.

For such an affordable laser printer, the ML-2570 prints extremely fast. After the initial warm-up time, letter-size paper prints at 25 pages per minute, making this one of the fastest of the ML 2000 series.

Having a maximum resolution of 1200 x 1200 dpi, the ML-2570 is great for printing text and B&W photos. The Toner Save feature, only available in it’s 600 x 600 dpi resolution, still produces printouts that are clear and readable.

For small-press desktop publishers using Wintel machines, Samsung’s software CD gives advanced printing features, like booklet printing and large-format poster creation. Sorry Mac and Linux users-- you’ll have to find those features in whatever publishing software you are using to get the same results.

As your business grows, the ML-2570 will still be able to meet your print needs.  With 32MB of non-expandable RAM, the ML-2570 can handle larger print jobs and multiple jobs (if shared or networked with an optional adapter). Understanding the printing needs of today’s businesses and the software applications and suites they often use, Samsung has installed PostScript and PCL6 emulators, as well as their proprietary SPL.

It’s nice that Samsung recognizes there are other operating systems than the one from Redmond. Samsung provides software support for the “Big 3” (Windows, Mac OS, and Linux). Now you don’t have to be chained to one operating system just because your printer can only support one.

An external network attachment will give the ML-2570 the ability to be a network server. But without a way to increase the printer’s memory, the ML-2570 will struggle with simultaneous job requests. For the cost of the network attachment, you can upgrade to a more powerful network printer.

CONS:
This is not so much a problem with the printer, just with the printer’s users. One disadvantage to the ML-2570’s smaller size is many people think it can be wedged anywhere without regard to its ventilation needs. To keep from cooking its internal parts and to prolong the printer’s life I would recommend (1) don’t put the printer where the air-vents are going to be blocked (leave 3” - 4” clearance), and (2) turn the printer off at the end of the day. (Remember what your mother would tell you about turning the lights off when you leave a room?)

In start-up, wake-up, and in operation, the ML-2570 produces 53 dB of sound, and 35dB of noise in standby. Think of 53 decibels as the sound of low conversations and 30 decibels as a quiet office. While 53 decibels may not be loud, it is if the printer is sitting next to you chugging off 50 pages.

The ML-2570 has a 25 second wake-up delay, with a 9s delay between print jobs.  A long delay when you turn on the printer in the morning isn’t a big issue, but the ML-2570 goes automatically into a power-saving sleep mode when it’s inactive. Add all this up and the 25 ppm speed boost is lost with all the delays.

INK / TONER NEEDS:
A big disappointment is the ML-2570 ships with a toner cartridge that’s only 1/3 full. This so-called “starter cartridge” prints about 1000 pages, or 2 reams of paper. So it might be a good idea to go ahead and buy the full yield toner the same time you buy the printer.
The ML-2570 will use the same toner cartridge as the ML-2010, with a standard yield of about 3,000 pages, or six reams of paper.
The Samsung does not offer a high-capacity toner for the ML-2570.

SOFTWARE:
The ML-2570 has one of the better software packages. Not only does it have the basic printing properties for Mac and Linux systems, but for Windows users there’s also an advanced printing section that allows for booklet printing, creating a large poster mosaics, and watermarks.
