> The main function of this section is to download and print bitmaps.

Bitmap printing consists of three steps: adding a bitmap; previewing the bitmap; downloading and printing the bitmap.

Precautions:

1. Before operation, make sure that the port parameters are set correctly and connected to the printer, otherwise the operation is prohibited. Please refer to the "\ref page_1_PortSet" page for port settings.
2. The following describes the BTP-R990 as an example (the interfaces of different printers may be different).

- Step 1: Add a bitmap

  - After the program starts to connect to the device, it enters the bitmap download interface.
  - Click the plus sign in the bitmap list to add a bitmap. The supported bitmap formats are bmp, png, and jpeg.
  - Note: The bit depth of the bitmap is required to be 1, 8, and 24. Bitmaps with other bit depths are not supported, and up to 8 bitmaps are supported.

- Step 2: Preview the bitmap

  - Click on the bitmap thumbnail: 1）Click the cross in the upper right corner of the thumbnail to delete the current bitmap. 2）Click outside the thumbnail crossbar to preview the bitmap in the preview area.
  - Precautions: 1）The bitmap editing area can be unlocked after previewing the bitmap. 2）You can edit the bitmap according to your needs, and support the conversion between the original image, grayscale and black and white.

- Step 3: Download and print the bitmap

  - When the "Mono" or "Gray" button is selected, the download button is unlocked: 1）Bitmap download supports downloading grayscale and black and white, which can be downloaded to ram or flash. 2） The bitmap in the entire list is downloaded to the printer when the bitmap is downloaded.
  - Unlock the print button after successfully downloading the bitmap: 1）Click the "Print" button to print the downloaded bitmap. 2）The currently selected bitmap is printed.
  - Precautions: 1）Please keep the settings when downloading, ie black and white or grayscale, ram or flash settings.
