The driver includes support for overlays like ‘Confidential’ and ‘For Your Eyes Only’. You can also print 2, 4, 6, 8 or 9 pages to the sheet, but there’s no scope for duplexing (printing on both side of the paper) unless you feed the paper through by hand. When we tried this, we saw several mis-feeds of multiple sheets of paper.
Canon quotes the printer as a 10ppm device, and it may get somewhere close to this in draft mode, but for normal printing we measured it at just over 6.5ppm. This is still closer to spec than many other manufacturers achieve and is a reasonable speed for a personal printer. At a rated 62dBA, the LBP-1120 isn't quiet when printing – certainly a lot noisier than a typical inkjet.
The machine completed our mixed text and graphics page in just 19 seconds, which is an impressive result even for a monochrome printer and is more impressive when you add that the 5 x 3-inch test photograph also took 19 seconds.
Print quality is good. Black text comes out dense and sharp with clean-cut edges and smooth diagonals and curves. It also handles colour originals well, assigning clean tone patterns to different shades, without any of the peculiar dithers you sometimes see when greyscale printers interpret colour.
Our test photograph was good in parts, though with default settings it came out too pale and with some blotchiness in smoothly-tinted areas of the print, such as sky tones. Detail is generally good, though some definition is lost in areas of shadow, even though these are reproduced too light.
The costs of running this printer are very simple to calculate, as it uses an all-in-one drum and toner cartridge, rated at 2,500 pages with five per cent cover. The cheapest we could find the EP-22 cartridge for was £35, giving a cost per page of 1.88p. This is not particularly cheap for a laser printer, where typical page print costs are closer to 1.25p per page.
Overall, considering its asking price, Canon’s Laser Shot LBP-1120 is a fine mono personal laser printer. While its greyscale photographic output isn't wonderful, that's not what most people buy a laser printer for. What they’ll be more than satisfied with is that it prints at a reasonable speed and produces good text and business graphics output.
