To clarify Nesreen - the 20-30 sheets reference was actually a recommendation of minimum to print in a year. Meaning - as long as you're printing at least once every 1-2 weeks, it becomes beneficial to invest in a printer from a maintenance and financial perspective. Inks can start to clog a little after a couple of weeks. And if you're printing less that 20 sheets, it is more cost effective to find a bakery or online business to fulfil.
Canon will be more than suitable for your needs. If you're into the hundreds a week that's when you need to look at alternative printers! Remember it can take a while to get to even 10-20 sheets a week if you're starting from scratch- it doesn't happen overnight.
I'd also consider buying your stuff from a specialised wholesaler like http://deco.uk.com unless you know some locally. We order from them and very reliable - they would likely ship to Jordan too...
