Once the paper is damp, you can use a hairdryer or put in the ventilated place to blow dry, pay attention not to put in the sun exposure, so easy to make paper deformation, resulting in paper jam. In addition, it is important to note that support for automatic double-sided output printer paper jam is particularly serious, so in the weather in the south, as little as possible to use automatic duplex printing
The development of copiers is more and more rapid, some brands also follow the trend of the market, launched a small convenient copier, no longer need to go to the search for a copy society. A cheap home printer in my family has been able to meet most of the printing needs, but many friends do not know how to use the home printer, now, we are in HP's 1518 series for introduction, briefly explain how to use the home copier,

Four Jam in the Output paper section
A Canon laser printer, whether printing large sheets or small sheets of paper, is jammed in the output paper. The paper tray is normal, just rub a piece of paper, and the lower carton will rub more than one paper.
Turn on the machine inspection, you can see a single sheet of paper smoothly through
information as far as possible on the top or near the top of the actor, to assign the error-prone task as far as possible to the lower actor. Let's apply this pattern to the register, we let register to maintain the sales, but delegate the work of receipt printing to a new sub-actor, we can call it Receiptprinter, here is its specific code:
Object Receiptprinter {Case
class PrintJob (amount:int)
class Paperjamexception (msg:string) extends Exception (msg)
}
Class Receiptprinter extends Acto
This part mainly realizes the low-level IO communication, but also involves the communication server's jam, the Non jam, the single thread, the multithreading and so on Operation mode, therefore realizes is quite complex. The diagram of the classes involved in this section is as follows:
From the above class diagram, it can be seen that this part of the class relationship is more complex, complex is not
The recent sudden interest in boost, but the boost installation is very troublesome, the online introduction of the method is mostly not comprehensive, found an article on the other compiler to install Boost method, try to change to c++builder2007 applicable methods and share, You have only done a simple test before publishing this article, please point out if you have any questions.

That is, the project for jam file description. OK, let's start with a new project, and click on Project, and there wi
