Samsung claims the ML-2545 is capable of 24ppm but on our five-page black text test it managed a fairly meagre 12.5ppm. As with so many printers, this is mainly due to preparation time before printing starts, something that doesn't have to be included in the ISO speed ratings for a machine. Oddly, toner save mode actually slowed the printer down, to 10.0ppm, when we would normally expect it to be slightly faster.
The longer, 20-page test saw the speed increase to 18.8ppm, which is a good speed for an entry-level mono laser like this, but still some way short of the number on the spec sheet. Our five-page text and graphics test was faster than the straight text document, giving 14.3ppm, and a 15 x 10cm photo printed on an A4 sheet took 17s, which is a reasonable speed.
The quality of prints is very much what we've seen from other Samsung mono lasers. Text is clean and sharp, at the printer’s 1200dpi resolution, with clean curves and diagonals. This is also true of line graphics and reversed text, white on black, is clean and full, showing no loss of thin ascenders or descenders.
Greyscales are also good, with no banding in areas of fill and large enough range of tints to distinguish even quite closely scaled, colour originals. Our photo test also showed clean variations in tone with little noticeable blotchiness – an excellent result on such a modestly priced printer.
The two combined drum and toner cartridges are rated at 1,500 and 2,500 pages and using the higher yield consumable gives a running cost for the Samsung ML-2545 of 3.04p, including 0.7p the paper. This is a very reasonable figure for this class of machine and shows that the company isn't clawing back the low asking price by increasing running costs.
The Samsung ML-2545 is another well designed mono laser printer from Samsung, with a surprisingly punchy print speed for a machine costing just over £80. The print quality is also well up to scratch and it's only the lack of duplex print and wireless connection, a couple of features which are becoming more and more standard, which detracts from this otherwise excellent entry-level machine.
