The 2355dn is rated at 33ppm, but our five-page text document took 20s, giving a real-world speed of 15ppm on short documents. When we switched on toner save mode, which produces lighter print, it took the same time to print, so it wasn't until we increased the file length to 20 pages that we saw a speed increase, up to 25ppm. You might get somewhere close to the headline speed on documents of 50 pages or so.
Duplex print is standard on the machine and our 20-page document printed double-sided took 48s, which is equivalent to a speed of 14.1 sides per minute. A single page copy came through in 14s and a five-page copy from the ADF still took only 18s. A 5-page, 10-side duplex copy took 1min 8secs. All these copy times are very reasonable and shouldn't leave you standing around at the water cooler.
Dell has also built in an Eco-Copy mode, which automatically prints two pages per sheet, either single or double-sided, at the tap of a single-touch button. If you specify duplex Eco-Copy documents, you can save three quarters of the paper, compared with printing in normal mode.
A 15 x 10cm photo print on A4 took a very snappy 10s to print and a full-page A4 photo from the USB socket completed in 44s. Although you can display filenames from a USB drive to select files for printing, you can't display image thumbnails, a function available on virtually all budget inkjet all-in-ones.
The machine prints at 600dpi and this is enough to produce clean text pages with smooth curves and diagonals. In comparison with some other workgroup multifunctions, such as the Brother DCP-7045N, text looks a little light, even more so in toner-save mode.
Greyscale graphics also suffer a little by printing light, and colours with distinctly different greyscales tend to print with similar tones. A photocopy of the greyscale page produced much darker fills and some noticeable banding. Against this, photographic images are well detailed and sharp. Although the 600dpi dots can be seen, they are less prominent than in some rivals.
The drum and toner cartridge is available in two page yields of 3,000 and 10,000 ISO pages and using the high-yield cartridge gives a cost per page of 2p. This is one of the lowest costs we've seen from a laser printer and as it's a single-piece consumable, cost of ownership should be very low.
Dell has engineered the 2355dn to be a robust, quick multifunction laser printer that is very cheap to run and includes several modern office essentials, such as touchscreen control, duplex print and copy, and a front panel USB port for direct print. It represents good value for money, when compared with its main competition.
