What is a good ink jet or laser printer that can print on paper the size of a business card?

Most printers can do that, just try to set the custom dimensions for the paper size. I cannot give a detailed step-by-step as this involves a procedure depending on what type of printer you may have. For black-only printing just pick any printer out there. However, I recommend HP printers. I know that most of the printers can do the job. But HP's efficiency and affordable ink cartridges give you that extra mile in your printing experience. I hope that answers your question. Thanks.

I've never seen a printer that could actually print anything smaller than about 3x5". I would not trust the roller feed to get the print straight on the card even if you could get it to work. As mentioned in other answers, print shops don't print on 3.5x2" cards. They print a whole sheet and then cut them. I make my business cards in small batches by printing them on 8.5x11" cover stock, 10 per sheet, with registration marks outside the cut area. I designed a laser cutting template and laser-cut the sheets into cards at TechShop.

You have asked-to-answer me, no doubt on Quora's recommendation. The bot is a bit stupid. Because I have one answer in the topic it thinks I am pretty hot. I'm not a home-printer review shop. But bluntly, and to your advantage, and towards the best finished product... Ring around a few copy shops and conventional print shops. Better still, go visit one and talk to someone away from the front counter, if you can. Why do I suggest this? If you are printing more than a few pages, the print shop will be cheaper and the finished product better. (Well, they for sure are here.) Start by laying out your cards on SRA4 or SRA3 oversize pages. (I assume the Mid-East uses standard paper sizes.) Space the cards apart by several mm. (Your chosen printer will tell you, but expect 10mm.) Use 'bleeds': anything that reaches the edge of the business cards (background colours or images, say) should extend outside the border by several millimetres. This allows the guillotine to be a mm or so off. (The final card size will still be correct, I promise!) Add 'crop marks': tiny lines in the page margin that mark the point where the printer's guillotine is to fall. (Make sure that they don't intrude on your cards, and make sure that each cut is marked, but don't worry if you think they will get cut off by the first few cuts.) Keep text three to five mm inside the intended edge of the card, for the same reason. If any of this is not clear, go in to a journeyman print shop and ask for a sample of what they'd like to receive. All* printers will accept digital files. All* printers will have big digital printers available for small runs. (Don't call them photo-copiers!) (* For a modern value of 'all') I understand that you might not be printing business cards, your question is clear. The specs are the same, whatever the final size of your project. As a bonus, black-printing-on-the-back is very cheap from a real print shop, just be sure the file you give has it lined up and oriented with the front.
