Frequently asked questions

Check Writer 123 is a web app for printing your own checks on any computer and printer. You type the payee, amount and date, watch a live preview, and print on blank check stock, pre-printed stock or plain paper. Nothing to install. Plans start at $9.99 a month after a 14-day free trial. See print checks online for a full walkthrough.

Yes. You need a computer with a web browser, a printer that takes letter-size paper, check paper, and your bank's routing and account numbers. Enter the check, review the preview, and press Print. Blank check stock gives the most complete result because the whole check, including the number line, prints in one pass. See how to print checks at home.

Create an account, add your bank account, choose your paper, write the check, then run a free Test Print on plain paper before using real stock. Most people finish setup in about ten minutes. The routing number lookup checks your entry, the amount in words is filled in for you, and the check number is assigned automatically.

In general, yes, for your own account, as long as the check carries what a bank needs: payee, amount, date, signature, and your bank's routing and account numbers. Each bank decides what it will accept, so ask yours if you are unsure. This is general information, not legal advice. See can you print your own checks.

No. Check Writer 123 is built for people who want something easy and fast. You fill in a short form, see the finished check on screen, and print. Saved payees, automatic check numbers and a free Test Print take most of the guesswork out. If you can use a web page and a printer, you can use it.

It depends on the result you want. Three-to-a-page blank check stock is the recommended choice and prints the full check. Pre-printed stock from your bank or a supplier works if you already have it. Plain letter paper is available for checks you deposit yourself. See what kind of paper you need.

Blank check stock is sheets of check paper with nothing printed on them, usually three checks to a page, each with its own stub. Check Writer 123 prints the whole check on it, including the bank name, your details and the number line along the bottom. You pick whether the check sits at the top, middle or bottom of the sheet. See what blank check stock is.

No. Any laser or inkjet printer that takes letter-size paper will do. Laser toner dries instantly, which suits larger batches. Inkjet ink needs a little time to dry, so let each sheet sit before you handle it. The printer is used through your normal print dialog. See what printer is best for printing checks.

The MICR line is the row of special numbers along the bottom of a check. Left to right it holds your bank's routing number, your account number and the check number. Banks read it to process the payment. On blank check stock, Check Writer 123 prints this line for you. See what MICR is and why it is used.

Yes. When you print on blank check stock, you choose top, middle or bottom, matching the third of the sheet that carries the check. The other two thirds are stubs. Pick the position that matches the stock you bought, then confirm it with a Test Print. See top check vs middle check paper.

Yes. Plain letter paper prints one complete, decorated check at the top of the page with a dashed cut guide, plus an optional back page with an endorsement area. It suits checks you deposit yourself or by mobile deposit. Whether any bank accepts a plain-paper check is up to that bank. See printing checks on plain paper.

That is up to your bank, and no software can promise it. Plain-paper checks are best when you deposit them yourself, for example by mobile deposit. For a check you hand or mail to someone else, blank check stock is the recommended choice. Ask your bank what it accepts, and try a small, low-risk check first.

Six designs: Blue and Rose (the default), Marble Green, Marble Gold, Marble Blue, Blue Linen and Plain White. The tint is only a look and adds no security. You can also print an optional back page with an endorsement area, which has its own alignment adjustment so it lines up on the reverse side.

Yes. On pre-printed stock, Check Writer 123 prints only the parts that change: date, payee, amount, amount in words, memo and signature. Your name, bank details and number line are already on the paper. Use a Test Print on plain paper to line things up first. See pre-printed check stock explained.

Choose pre-printed stock for the bank account, run a free Test Print on plain paper, and hold it against one real check in front of a light. If the printing sits off the lines, nudge the alignment, test again, then print on the real stock. The settings are saved per bank account. See setting up pre-printed checks.

Choose blank check stock if you want the most complete, flexible result, since it prints the whole check and you can change bank details any time. Choose pre-printed stock if you already have a supply. Choose plain paper for checks you deposit yourself. See how to choose the right check paper.

Yes. You can add several bank accounts, each with its own name, address, logo and signature, and each remembers its own paper choice and alignment settings. The Occasional plan includes 2 bank accounts, the Mid Tier plan 4, and the Unlimited plan has no limit. See printing checks for multiple bank accounts.

Type it in and Check Writer 123 confirms that it passes the standard routing number checksum, then suggests the bank name that goes with it. That catches mistyped digits right away. Still compare the number with one of your existing checks or your bank's website, because a number can pass the checksum and still belong to a different bank.

Yes. Upload a logo for each bank account. For the signature you can upload an image, draw it on screen, type your name, or leave it blank so you can sign by hand after printing. See printing a check with a signature and adding your company logo.

Check Writer 123 serves every page over HTTPS, stores passwords as salted hashes, and does not sell your data. Card payments go straight to Square, so card numbers never reach its own servers. Read the security page for details, and keep your own computer and account password protected.

Keep it locked up. Blank check stock is a fraud risk because anyone holding it could try to print a check, so store it in a locked drawer or cabinet and count the sheets now and then. Shred spoiled checks instead of binning them whole. See how to avoid check printing scams.

There are three plans. Occasional is $9.99 a month for 20 checks and 2 bank accounts. Mid Tier is $13.99 a month for 60 checks and 4 bank accounts. Unlimited is $29.99 a month for unlimited checks and bank accounts. You also buy your own paper and ink. Compare the options on the pricing page.

Yes. You get a 14-day free trial, and you do not need a credit card to start. You can use every feature and print real checks from the first day. If you decide to continue, you pick a plan. If not, nothing is charged. Start from the print checks online page or go straight to signup.

A check counts when you press Print, which is also when it is saved. Reprinting a saved check and running Test Prints do not count. Nothing is saved until you press Print, so there are no drafts using up your allowance. A printed voided check does count as a printed check.

Yes. Every plan has every feature, including batch printing, the check register, saved vendors and attachments. The plans differ only in how many checks you print each month and how many bank accounts you can keep. See the pricing page for the current limits.

You can cancel any time in Settings. There is also a 30-day money-back guarantee on your first payment. Card payments are handled by Square. If you are still unsure, the 14-day free trial lets you try everything before paying anything. The full terms are on the refund policy page.

Yes. You can enter up to 25 checks in one go and print up to 50 selected checks together. That suits a weekly bill run or a payroll day. Each check still gets its own number and is saved to your register. Test one first, then print the batch. See printing multiple checks at once.

Open the saved check in your register and reprint it. Reprinting is free and does not count toward your monthly limit, so a jam, smudge or misfeed costs you only the paper. The reprint keeps the same check number and details. See how to reprint a check.

Use the voided-check printing option, which prints a blank check with a large slanted VOIDED mark. It is handy for setting up direct deposit or keeping a record. A printed voided check counts toward your monthly total. For a check that has already gone out, write VOID on it and note it in your records. See how to void a printed check.

Your check register lists every printed check, and you can search it. Each check also keeps an activity history. A register report can be printed, downloaded as a CSV file, or exported in full, which is useful at month end or when you send records to your accountant. See keeping a digital record of printed checks.

Yes. Add invoice lines to the stub so the person you pay can see what the payment covers. You can paste the lines straight from Excel or Google Sheets instead of retyping them. The lines print on the check stub. See how to print vendor checks.

Yes. You can attach one supporting document to a check, such as an invoice, as a PDF, PNG or JPG up to 1 MB. It can print after the check, so the paperwork travels with the payment, and you can add a different one to each check. Use it for an invoice, a receipt or a remittance slip.

Yes. Keep a saved list of vendors and employees so you type a name once and pick it next time. When you write a check, the amount in words is filled in for you and the check number is assigned automatically. Delete a check and its number is released for reuse. See how to print contractor checks.

Yes. It runs in your web browser, so there is nothing to download on a Mac. Connect any printer your Mac can print to, open the site, and print. Choose the actual size or 100 percent scale in the print dialog. See check printing software for Mac and printing checks on a Mac.

Yes. Open the site in your usual browser on a Windows PC and print to any printer installed on that computer. There is no program to download or update. In the print dialog, pick US Letter paper, a scale of 100 percent, and turn headers and footers off. See check printing software for Windows.

Yes. Check Writer 123 runs entirely in the browser, which is what a Chromebook is built around. Print to any printer your Chromebook can reach, using the standard print dialog at actual size. Run a free Test Print first to confirm alignment. See check printing software for Chromebook.

No. Check Writer 123 is a website, so there is nothing to download, install or update. You need a current web browser, an internet connection and a printer, and it works the same way on Windows, Mac and Chromebook. Setup takes about ten minutes, and you can try it free for 14 days. See how it works.

Run a free Test Print on plain paper, hold it against a real check or stock sheet in front of a light, and see which way it is off. Then nudge the whole page left, right, up or down, test again, and repeat. The back page has its own adjustment. Settings are saved per bank account. See how to align a check.

A Test Print prints the check with TEST PRINT watermarks across it, so it can never be mistaken for a real check. It is free and never counts toward your monthly limit. Use it on plain paper to check layout and alignment before you load real check stock, and any time you change printer or settings.

Usually the print scale or the paper position is off. Print at 100 percent or actual size on US Letter, and make sure the top, middle or bottom setting matches your stock. If it is still shifted, nudge the page up or down in the alignment tool. See why a check prints too high or too low.

Use the separate MICR adjustment, which moves the number line without shifting the rest of the check. Run a Test Print, compare it with a real check, and nudge the MICR line until it sits where the bank numbers belong on your stock. The change is saved for that bank account. See what to do when the MICR line prints incorrectly.

Most often the browser or printer is shrinking the page. Set the print dialog to US Letter, 100 percent or actual size, and turn headers and footers off, then try a Test Print. If the check still sits too far left or right, nudge it horizontally. See fixing check printing alignment.
