If you've run out of checks and need a check or checks printed that same day then you can go to your bank and they can print you out some starter checks that you can use like normal checks.
There might be a small fee for the printing of the starter checks but that is one way you can get checks printed the same day.
There might also be some printing shops that do check printing for people although there will also be a charge.
Or you can download and install some check printing software on your own computer and then use some check printing paper to print out checks using your own printer.
You can print your own checks from your computer and printer using a regular printer.
You'll need some check printing paper though to print the checks on otherwise the checks won't be accepted by the banks.
So you'll need to buy some check printing paper and also you'll need some check printing software for your computer that you can buy online and download and install on your computer.
Then you can print the checks out with your routing number and checking account number and name and address on your checks.
Then the checks can be used like normal.
Or you can just go online and order checks cheaper than the bank and they will send you the checks and print them out for you.
