The function of the printer is artificially set. Compared with the human brain, the printer will be very "mentally handicapped", because as long as we simply perform some operations, we can easily deceive the "trust" of the printer. If you do n’t believe it, please take a look at the following printing "cheats", good at using these printing "cheats", and sometimes can achieve unexpected results in the actual printing process! 1. Paper type "fraud" If the A4 printer is installed in the computer, then in the Word 2000 application or other applications, there may be a phenomenon that A3 paper cannot be selected. If you want the Word 2000 application or other applications to support A3 format printing, you can artificially add a "virtual" printer that can print large format, so as to "deceive" these applications; the following is the specific implementation steps of the method : First click the "Start" menu on the system desktop, and then click the "Settings" / "Printers and Faxes" command from the pop-up submenu, in the subsequent printer list interface, double-click the "Add Printer" icon, in In the pop-up printer add wizard window, the Windows system will automatically search for the printer that has been connected to the computer; since the real printer is not installed now, the wizard system will naturally prompt that it will not search for any valid printer; At this point, you can click the "Next" button to manually install the printer; when the wizard window prompts you to select the printer manufacturer and model, you can choose a printer with the model "Epson LQ-1600K" (Figure 1 (Shown), because the printer supports large-format printing; after that, you can continue to complete other installation operations of the printer according to the screen prompts; Next, you can open the Word 2000 application editing interface, click the "File" / "Page Setup" command in the menu bar in turn, in the pop-up page setup dialog box, find and open the paper size selection setting item, at this time you You will find that there is still no A3 paper to choose from. However, if you execute the "File" / "Print" command in the menu bar again, and select the "Epson LQ-1600K" option in the printer name setting box, and then click the "Cancel" button, you will be in the "Page Setup" In the dialog box, you can see that the A3 printing format is available. Of course, this kind of "fraudulent use" of paper size cannot allow A4 printers to print out the contents of A3 format, it only provides convenience for editing and previewing the A3 format. 2. Mode "fraud" As everyone knows, the main printing modes of inkjet printers include three, one is color printing mode, one is grayscale printing mode, and the other is black and white printing mode. Under normal circumstances, the choice of printing mode should be determined according to the type of printing content. For example, when printing a black and white photo, the black and white printing mode should be selected. In fact, sometimes selecting the correct printing mode does not guarantee that the printing effect is at its best. On the contrary, selecting other printing modes may result in unexpected printing effects. For example, an inkjet printer considers that it usually only handles some text materials and forms, so only one monochrome ink cartridge is installed. In order to avoid the print driver constantly detecting color ink cartridges, I set the print mode to black and white in advance Print mode. If you want to print a black and white photo recently, scan the black and white photo to the computer according to the conventional method, and then set the output precision of the printer to "high", and specify the black and white printing mode to start printing the photo. The actual printable Black and white photos don't have any sense of layering at all, and the effect of the photos is very different. 3. Ink "fraud" Under normal circumstances, when the "ink-out" signal in the control panel of the inkjet printer flashes, the printer will prompt you to replace the ink in time to continue using the printer; in fact, at least about 15% of the ink remaining in the print cartridge , They are usually used to protect inkjet printer heads. But if you are anxious to print materials, and the printer's "ink-out" signal keeps flashing, you can use the following "scam" to borrow the residual ink in the ink cartridge. The following is the specific "scam" step : When the "ink-out" signal light in the control panel of the inkjet printer flashes, you may wish to open the upper cover of the inkjet printer, and then you can see the ink cartridge holder, where the print cartridge is placed; In order to take out the residual ink cartridge in the ink cartridge holder, you need to press and hold the "Reset" button in the printer control panel, then the ink cartridge holder will move to the right along the carriage slide bar until it stops at the position where ink can be changed ; At this time you open the lid of the ink cartridge, so that you can see the remaining ink cartridges; Considering that it is not installing a new ink cartridge now, you should never take the ink cartridge out of the cartridge cartridge at this time. If you accidentally forget to take the ink cartridge out, you must put it back in place in time, otherwise the print nozzle After the ink meets the air, it will be weathered and condensed, which will easily cause the nozzle to be blocked by the dried ink and eventually cause the failure to print; Next, as long as the ink cartridge cover is closed again, and the upper cover of the inkjet printer is closed; press the "clean" button in the printer control panel, then the inkjet printer will re-execute the ink refilling action, and wait until the After the execution of the action, you will be surprised to see that the "ink-out" signal in the printer control panel is not only normal, but also indicates that the ink in the ink cartridge is full. When trying to print materials, the inkjet printer works normally. Of course, such "fraud" method can only be used as an emergency, not multiple use, nor suitable for long-term use, otherwise the service life of the print head will be seriously affected.

Later, the author set the print mode to "color print mode" again, and reprinted a black and white photo. The level of the photo printed this time was very clear, and the overall output effect was unexpectedly good; the same printer, the same photo, the same Printing paper, why is the printing effect so wide? The truth is simple! When working in black and white printing mode, the computer simply converts all the image details in the photo into black and white, and only a small amount of gray components are added between the image transitions, so the printed effect will lack a clear sense of hierarchy . When the color printing mode is selected in the black and white printer, the computer will add a lot of gray tone components to the color transition area of ​​the photo when processing the photo, thereby avoiding excessive accumulation of black ink in the local area, so this printing effect is also natural It is better than the black and white printing mode.
