Maybe daily to see the printer that you are printing a parallel port or USB interface and the computer is connected to; however, the printer prints in addition to the parallel port or USB interface, you might have a serial port, we must not think that this is just a well-display serial interface, because as soon as the printer of the parallel port or USB interface experience a breakdown in normal use, the serial port can make their own role, help printer to serial communication fashion emergency printing.

或者我们常日见到的打印机，都是堵住打印并口或USB接口与计算机拆开的；不过也有的一些打印机除了具有打印并口或USB接口之外，还不定具有一个串口，我们万万必给以为这个串口不光是个部署而已，因为一旦打印机的并口或USB接口碰到障碍不克不及变态搁置时，该串口不离能阐发自己应有的功用，帮忙打印机以串行通讯的方法来达不败济急打印。

The best ink in the off-time after opening the packaging end use, not to open the ink on the outside when not in use Add to carton packaging, the cartridge so as to avoid talking about the dust falling into the hands of the next use of the dust caused by plugging into the nozzle first, the head following a reset state of ink wash sponge pad, open the front cover, press the Print Paper knife, move out, the hair can not suction clean cloth towel or sponge the ink pad, a large amount of about 10 days, then wash first, because each sponge pad is printer ink wash drawing of fatigue, if the dust and fatigue more ink will be solidified with the protection of Garra and print images will be the first flush, if the plug was found, and if the use of cleaning 3 seconds is not normal use, we must enter the printer maintenance menu kk2 or use kk1 cleaning, large format printers and a small printer operation principle is similar, if the correct maintenance and use, it will increase the service life, which Like is like a car, but also for us to maintain and are familiar with it

墨水最好在拆开包装后断时间内使用完，不要把打开的墨水放在外面，不用时包装好放入纸盒内，以免墨盒嘴上落入灰尘，下次使用时灰尘进入喷头造成堵头情况，喷头复位状态下面有一个洗墨海绵垫，打开前盖，按下打印切纸刀，往外移，用不起毛的纸巾或布吸干净海绵垫的墨水，用量大的话大约在10天清洗一次，因为海绵垫是打印机每次冲洗时吸取疲墨水的，如果灰尘多就会和疲墨水凝固在一起，对墨头的保护和打印头冲洗会有影像，如果发现堵头情况，如果使用清洗3秒还不能正常使用，我们要进入打印机的维护菜单用kk2或kk1清洗，大幅面打印机和小打印机的操作原理是差不多的，如果正确的维护和使用，它的使用寿命就会增长，这也好比一辆轿车一样，还要我们去维护和熟悉它

Section 1 discusses the advantages of medical film printer and USB, and put forward one elementary design scheme of the system. The principle of laser printer and the holistic design scheme of system are presented detailedly in Section 2, while Section 3 expounds the technology of USB. Section 4 discusses design scheme of transfer system of the laser printer - includes the development of USB device and CPLD. The test of holistic laser printer and effect picture of medical image are presented in Section5. In the end, a review of this system and some bugs are put forwards at present.

Print ribbon is installed, we need to print frame first uninstall it from the printer, uninstalling the device must be near the print head from the location you pull up hard, in order to easily print aircraft had come from the printer ; the following, we also need to open the print frame, taking into account different models of printers that it installed on the structure of the printing frame is not exactly the same, so the installation of ribbon winding method is not exactly the same, we have to uninstall it before the original band, we a good look around the ribbon before the correct method, or else do not print the right way to install the ribbon will not be able to function properly, but also may lead to the printer not work correctly.

在安装打印色带之前，我们需要先将打印架从打印机中卸载下来，在卸载该设备时，必须先从靠近打印头的位置处用力向上拉一下，才能把打印架轻松地从打印机中拿下来；下面，我们还需要将打印架打开，考虑到型号不同的打印机它的打印架安装结构并不完全相同，因此色带的安装缠绕方法也不完全相同，我们在将原色带卸载下来之前，一定要好好地观察一下色带以前的正确绕法，否则不按正确方法安装的打印色带不但不能正常发挥作用，相反还有可能导致打印机无法正常工作。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides.
