\# Configure printings With the printing feature, you can manage prints directly from your application and obtain them from the assigned terminal or send the print to a Bluetooth printer. > NOTE > > If you want to use a Bluetooth printer, it must be paired with the Point terminal. See \[Configure Bluetooth\](https://www.mercadopago.com.ar/developers/en/docs/smartapps/terminal-features/configure-bluetooth) for more information. With this feature, you can print purchase tickets and integrate custom prints. This functionality is useful for businesses that need to print complementary receipts, such as coupons or images. -------|-------------| | Taxed Invoice (33) and Exempt (34) | Refers to the tax document that has legal validity before the Internal Revenue Service (SII). | | Taxed Receipt (39) and Exempt (41) | Refers to the document that the customer receives when making a purchase, which has accounting and tax validity. | See below an example of how to print DTE (Electronic Tax Documents).

::: :::TabComponent{title="Custom printing"} The \`print\` function from the \`BitmapPrinter\` class of the \`MPManager\` object can also be used to create custom text printings. This is accomplished through a pattern called Custom Tag, which consists of sending a \_string\_ with different control tags for subsequent interpretation by the Mercado Pago system, resulting in a physical receipt. These \_tags\_ allow you to adjust the format and appearance of printed documents, ensuring greater control over text style and structure. To perform custom printings with the Point terminal printer, you must include in the \`customTagToPrint\` field a \_string\_ with the desired content, formatted using at least one of the supported \_tags\_. The content for this attribute has a minimum of 100 characters and a maximum of 4096, including the \_tags\_ themselves. Below, see the different available tags and their functions. | Tags | Function | Example | |------|---------|---------| | \`{b}\` | Bold | \`{b}Bold text{/b}\` | | \`{w}\` | Large font | \`{w}Large font text{/w}\` | | \`{s}\` | Small font | \`{s}Small font text{/s}\` | | \`{br}\` | Line break | \`{br}\` | | \`{left}\` | Align left | \`{left}Left aligned text{/left}\` | | \`{center}\` | Center text | \`{center}Centered text{/center}\` | | \`{qr}\` | Print a QR code representing the sent text | \`{qr}Text{/qr}\` | | \`{pdf417}\` | Print a barcode | \`{pdf417}Text{/pdf417}\` | See below an example of how to perform custom printing.

::: :::: ::::: :::AccordionComponent{title="External printing via Bluetooth"} To perform printing on an external printer, you must first \[pair it with the Point terminal via Bluetooth\](https://www.mercadopago.com.ar/developers/en/docs/smartapps/terminal-features/configure-bluetooth). After pairing, use the \`print\` function from the \`BluetoothPrinter\` class of the \`MPManager\` object to perform the printing. In the \`dataToPrint\` field, provide the text sequence to be printed. > NOTE > > If there is already a paired printer and you need to select it, use the search printers function to get its location. Then, provide the printer address in the \`address\` field. See below an example of how to perform printing.
