Since I am a translator in my company, I have to communicate with foreigners almost every day, sometimes, we would send some documents to foreigners, my boss always tells me to transfer my word format document to pdf format, I don’t know why, so last time, I checked some information on the internet, which told me that print poster from pdf would be much easier than print from word format, so I had been practicing that ever since. And I believed poster printing pdf is just the thing I sent to our clients. However, yesterday, one of our clients called me, telling me that the pdf I sent to him was incapable of being printed out, I was surprised. Since I had always thought of print pdf as poster was the same one as my pdf, I did not know print poster pdf would require some other things. From what our client told me, he said to print a poster on multiple pages, I had to download print poster software, then making some adjustment to the pdf file I sent to them, so print a pdf document was available for him. Since I did not know anything about software, so I asked him if he could download this softward himself, but it turned out he knew nothing about computer, le alone the print posters software, so it seemed I had to do it on my own. This was a really tough thing, before I surfed on the internet, I thought I could do it myself after downloading some kind of software from internet, but when I checked the information on the internet, I found out there were too many print multiple pdf files on the internet, honestly speaking, I was not able to identify which one was better than the other one, so I thought to myself, why the hell, I could download one, and then I could check if the print to pdf free download would work, if it did not, I could always use another one. So I just downloaded one poster printing software in my computer, then I started to do some research on this software, how could I use it to change something in pdf so that the pdf will be the same without any distortion? Since you know, the printer, nowadays, always adopted 4 color poster printing, so if you did not make some changes in the pdf document, the poster you printed out would not the same as you saw on the computer, which was the same as word format, remember how many times when you typed so many words on your computer, you saved the document as the word format, then you took the document to print, then you would find that the layout in the word document had completely changed. That was because some other people used different software, when your document was put on that computer, some layouts would be changed. That was why printing multiple pdf files would be changed on different computer, but if the two computers shared the same print to pdf free adobe or software print poster, the printing to poster thing would be easy. I asked help from my friend Jim, who told me that print pdf document was rather easy to get, you could always use some banner printing software posted by some kind-hearted people on the certain webpage, so you could use this print adobe pdf free to help you do this poster printing. From his experience, the free poster printing was available with certain knowledge about adobe and photoshop, I promised him that if he could teach me how to do this, the expense of his paper;paperboard printing would be on me.
