A ZIP file is simply a file filled with information, data or documents that have been through a compression process to minimize the size of the files making them quicker to download, easier to archive and more likely to be received via electronic mail because the compressed format takes up less storage space and uses fewer system resources.

It is easy to make a zip file by PDFcamp Printer and you don’t need to know anything about HTML code. There are no interface concerns. Basically, you just open the program and follow the instructions I give to you to create a zip file. You name the file and choose where you want it to be stored in your system.

The following snapshots will be a course for you to learn how to use ZIP compression when print documents to pdf files by using PDFcamp Printer,which is easy to master.

Step1.Click “file”—“print”—“properties”.

Step2.Click “Compression” in properties and check “compress using” and select “Zip”in dropdown lists and click “OK”.

Step3.Save your file in some folder you like and name the new file.Then click”save”.

You can see the new pdf file generated by PDFcamp Printer.If the size of original document is big,you will find it will be smaller after printing.

The aim of Jpeg compression is to take full-color (and gray-scale) "real-world" scenes and reduce the file size of images for storage and transmission. While capacity and bandwidth have improved dramatically over the last decade, the increased size of images make Jpeg still relevant for digital camera users and websites.

PDFcamp Printer can minish your file size through an important function in properties and I can show you how to use it.

You can insert full-color or gray-scale images in your original file and press the hot key “Ctrl”+”P” or click “file”—“print”.

Then click”properties” in which you should open the “compression” item to check compress use of “Color/Grey Scale Images” and select “JPEG Medium” in the combo box.

At last you can click “OK” and save the new file in a location of your computer.

The ultimate aim of using JPEG compression in PDFcamp Printer is to make the size of your pdf file smaller and smaller,which is easier to open,buffer,store and transfer.

What is CCITT Group4?

Many facsimile and document imaging file formats support a form of lossless data compression often described as CCITT encoding. The CCITT (International Telegraph and Telephone Consultative Committee) is a standards organization that has developed a series of communications protocols for the facsimile transmission of black-and-white images over telephone lines and data networks. Group 4 is a protocol for sending fax documents over ISDN networks.

In brief,CCITT Group4 is a kind of compressing algorithm which can compress monochrome images in a smaller size.

If there are many black-and-white images in your document which you want to print to pdf file,it will be a big size generated file after conversion.So the best way is to compress them into a smaller size one by some algorithm.In PDFcamp Printer,you can compress all black-and-white images through CCITT Group4 algorithm and you can master the way by following me.

1.Open your file and press “file” and “print”.

2.In properties you should find the item”Compression”.In Monochrome Images(black-and-white)item please check “compress using”and select CCITT Group 4 in the dropdown list beside.Then click”OK”.

3.Save and name your generated file.

If there are a lot of black-and-white images in your original file,the compressed generated pdf file will be smaller in size than the uncompressed one by using PDFcamp Printer.
