Having a broken printer is certainly not one of the most pleasant of experiences when dealing with your IT equipment, but it doesn't mean you should just send it straight to the nearest printer repair shop without consideration.
One of the best things you can do is to make sure that when you send your printer to be repaired, you send it to somewhere reputable where you are confident that you will get the printer back in full working order, and that the printer repair will come with an assurance that those repairs will have solved the problem for you.
You should consider asking friends, family and colleagues if they have any experience in dealing with the printer repair shops in your area, and whether or not they found that specific person or company to be reliable. If you are unable to locate any recommendations in that way, then you can also look for the review sites online, and see if there are any reviews for the printer repair shops that you will find listed on those sites.
Another area you can look at if you are struggling to choose between repairers is to have a look at the website of your printer's manufacturer. They will often run their own accreditation schemes where printer repair technicians will have to pass exams and study a course set by that manufacturer. They will actually have a list of the technicians in your area that will hold these if they run such an accreditation scheme.
Of course, you will be wanting to ensure that you spend as little as possible on the actual repair itself, so it may be an idea to check if your printer is still within warranty, which would be an almost certain way to avoid some of the costs incurred in these repairs.
Having exhausted these options, and still haven't found the best place to arrange your printer repair? If this is the case, then you may want to consider just popping in and having a chat with one of your nearby printer repair shops. Talking to someone will often give you a first impression about what they are like. Look out for any signs indication that they belong to any trade bodies, or any qualifications that they will display in their shop, and this should help you choose somewhere to repair your printer.
