I am trying to print a pdf document on my Canon Pixma i500 and it won't print

Try with following tips
1. In the print dialog, click on the Advanced button (lower left)
2. Check the box to "Print as Image".

Can you save your document to PDF and try to print it again? Sometimes there is 'corrupt' postscript information in your file, and when you make a PDF first, it will be solved. If you do not want to make a PDF first, try to print your document page by page. It also could be a memory problem. That sometimes will be solved by shutting down your printer, wait a minute than switch it on again. So, you can try these three things:
1: Shut down your printer, wait a minute switch it on again, than try to print your document
2: Print your document page by page
3: Make a pdf of your document first, than print the pdf
Succes!

Hi, make sure if the pdf you can't print is restricted by owner password which prevents you from copying, editing and printing pdf files. User a pdf password remover to remove pdf password. AnyBizSoft has a product like this.

copy the content in MSWORD and print it

Go on Canon web site and look for updated drivers for your operating system.  Also get updated drivers for your word 07 by clicking on check for updates in one of the top tabs when you got Word open.

Can you printer other kinds of documents aside of PDF?
Maybe you have something in the PDF that is causing an issue with the printer. Will the PDFs print on you mom's older printer?

Type of document usually doesn't have any bearing.

An incorrect driver perhaps. Go to Canon's website and locate the latest driver and any updates for your model.

If you can print the nozzle test then that proves most of the electronics, it could be the driver is screwed.
Since you can get something out that is intelligent e.g. the larger font lettering then it is processing the file sent to it.
By that I mean rasterising it, converting it to dots of ink, so it can print onto the page as the heads moves back and forth.
Why not try another computer and connect your printer to that one, or try a different file, or even send it a file you've printed successfully in the past before you started to have this problem.

1: check in the printer properties( page setup ) is it latter then make it A4
2: clean the roller
3: also when u printting check with uper try not from try 2
if its printing proper then try is touching roller

When you print on the PDF, before you will start printing check the settings of the printer. You can see the printer named? find the printer you are using.
