I have a wireless canon printer and this strange thing happens that whenever I give print command, it takes two pages at once, prints on one and the other comes out blank but in a rather crushed form. I can put one page at a time but I need a permanent solution to this problem.

I am using HP printer connected, with my laptop, but recently the alignment of the printing has totally disturbed, affecting the quality of prints, with some printing missing in between despite ink Cartridge being full. Has it something to do with printing settings, or is it hardware problem, any suggestions to avoid it?

What could be the cause of ink leakages in printers? I went to visit a friend yesterday in her house and I found her cleaning trying to clean some ink drops inside the printer. I asked her why and the only answer she gave me was one cartridge is bleeding. I would like to know what are some of the possible ways of such conditions and if any precautions can be taken to avoid that too. Thank you.

What are the steps to follow to service my printer by cleaning or wiping off the dust inside the printer? I am business student in one of the senior high schools in Nigeria and I have a laser printer in my room. The printer is prone to dust because of an ongoing road construction in my vicinity. How do I go about it because the printer is quite new and do not want it to break down. Thank you.

Hello! I am experiencing some issues with my HP Officejet Pro 8500 printer. It is in perfect working conditions, and normally prints without problems. However, it refuses to print after going to sleep mode. It works fine as soon as I turn it on, but won´t print after it has been in sleep mode for a bit. It is not a major problem, but still an inconvenience.

Is there a solution for this? 

My room has two computers. I am connecting the first computer to a printer using a USB cable. I like it better than a wireless connection. I need help on connecting the second PC from my printer so both PCs will use one printer. Do I need any special software or hardware to make this work? Thanks.

I have an HP business inkjet 1200 and prior to reformatting my computer, it was working very fine. But nowm it is throwing an error message stating that the 'Driver is Unavailable'. I tried the software, Print and Scan Doctor and it says, I do not have the installation files and gives me a link to download it. When I click on it, it sends me a calculator. What is that? Worst is, it keeps on re-opening. Anyone who can help? I'm running Windows 8.
