Although there are many currently on the market specifically for the commercial inkjet printer to print the document, the text print quality to ensure close to laser printing at the same time, basically to achieve roughly 15ppm output speed (in some cases up to 20ppm or so), but also have the color output capabilities. But in the face of continuous high-volume document printing operations, ink-jet printer or looks bloated, and then purchase a manual to meet the heavy black and white laser printer is clearly a more sensible choice. Lenovo LJ3550DN black and white laser printer LJ3550DN from Lenovo this document is printed products for the bulk of its engine speed and configuration of high, also has good scalability, sufficient to meet the output operating heavy applications. And we introduced at the beginning of the LJ3500 compared, LJ3550DN in virtually no change in appearance, but in a functional configuration has been further strengthened, should be considered high with LJ3500 version. By product type, the careful reader can easily find: This LJ3550DN standard automatic two-sided printing unit and provides a network connection, random print memory also increased 32MB (the maximum can be upgraded to 512MB, LJ3500 configuration is 16MB memory), in dealing with complex page or batch printing advantages. Configuration on upgrade, so LJ3550DN can respond more complex applications. Compared with the price of products and, LJ3550DN configuration can be considered more "luxury", it equipped with a speed of up to 28ppm print an engine, and standard network connectivity, to integrate rapidly into more than your share shared use environment. And high-load natural match print paper supply capacity is adequate, standard models of the 250-page standard paper tray and 50-page capacity of the multi-feed can meet the printing needs of a typical office environment. For greater load printing needs of users, you can then install two optional 250-page capacity paper tray selection, a total capacity of 800-page summary of paper supply capacity to meet most applications should be a very ample. Meanwhile, LJ3550DN also built a very high availability automatic two-sided printing unit, without complex operation can be easily double-sided printing, could effectively cut paper consumption, reduce the cost of the printer to use, but also to print out the document appears more professional. LJ3550DN initialization work is worry, driver CD has an intuitive, vivid video illustrates the installation, installed, printing supplies, connect the USB cable and power cord, and then select the good of your connection, the rest of the work Smart Wizard installation program automatically. Objective performance tests, LJ3550DN very successful rate of completion of all of the commercial printing speed test project only took 5 minutes and 7 seconds. Both types of document to print ordinary text or graphics output of the complexity of the document pages, paper out very smoothly with no pause; In addition, the response speed of the printer soon, the default settings of the page output time of less than 10 seconds, at the same price The product has strong speed advantage. Output from LJ3550DN proofs of view, it prints fine characters, words sharp edges, most of the four pounds of English characters can be easily identified in the visual distance. Default, graphics and photo performance is acceptable to use performance tint transition region of the network jitter algorithm showed relatively slight, gray-scale normal, vector lines are more detailed, but a solid color fill part of the band can see clearly, but to meet the office document output is a good enough. Be noted that in the default half-tone (the Advanced tab in the "Print Setup" for automatic) control, select 1200dpi print screen contrast there are relatively large, will lose some shadow detail, if you want better graphics Output results suggested that the "Print Settin gs" to manually, and set the page, select "improved grayscale" option, change the output after the effect will be greatly improved, the picture contrast medium, many levels of detail can also normally displayed. Lenovo LJ3550DN function or performance are both still fairly good strength in the price of products with strong competitive ability of its high output enough to satisfy those print jobs to a busy output needs of small office environment, to 5,000 yuan but not quite offer value for money.
