Struct Config 

pub struct Config { /* private fields */ }

Implementations

impl Config

pub fn new(model: Model, serial: String, media: Media) -> Config

Initialize configuration data with default values.

This method receives model and media. They are not modifiable after the initialization.

Example

use ptouch::{Config, ContinuousType, Media, Model};
 
let media = Media::Continuous(ContinuousType::Continuous29);
let model = Model::QL800;
let config = Config::new(model, "serial".to_string(), media);

pub fn enable_auto_cut(self, size: u8) -> Self

Enable auto cut after printing specified number of labels.

Arguments

• size - Number of labels to print before auto-cutting (1-255)

Example

let config = Config::new(Model::QL820NWB, "serial".to_string(), 
                        Media::Continuous(ContinuousType::Continuous62))
    .enable_auto_cut(3); // Cut after every 3 labels

pub fn disable_auto_cut(self) -> Self

Disable automatic cutting of labels.

When disabled, labels will need to be manually torn or cut.

Example

let config = Config::new(Model::QL820NWB, "serial".to_string(), 
                        Media::Continuous(ContinuousType::Continuous62))
    .disable_auto_cut();

pub fn cut_at_end(self, flag: bool) -> Self

Control whether to cut the tape at the end of a print job.

Arguments

• flag - true to cut at end, false to leave uncut

Example

let config = Config::new(Model::QL820NWB, "serial".to_string(), 
                        Media::Continuous(ContinuousType::Continuous62))
    .cut_at_end(true); // Cut at the end of job

pub fn high_resolution(self, high: bool) -> Self

Enable or disable high resolution printing.

High resolution doubles the vertical resolution from 300 DPI to 600 DPI. When enabled, image height should be doubled accordingly.

Arguments

• high - true for 600 DPI, false for 300 DPI

Example

let config = Config::new(Model::QL820NWB, "serial".to_string(), 
                        Media::Continuous(ContinuousType::Continuous62))
    .high_resolution(true); // Enable 600 DPI

pub fn set_feed_in_dots(self, feed: u16) -> Self

Set the feeding length in dots.

Controls how much tape is fed before printing starts. Different media types have different valid ranges.

Arguments

• feed - Feed length in dots

Example

let config = Config::new(Model::QL820NWB, "serial".to_string(), 
                        Media::Continuous(ContinuousType::Continuous62))
    .set_feed_in_dots(150); // Set feed to 150 dots

pub fn two_colors(self, two_colors: bool) -> Self

Enable or disable two-color printing (black and red).

Only supported on QL-820NWB with compatible red/black tape. When enabled, use print_two_color() method instead of print().

Arguments

• two_colors - true to enable two-color printing

Example

let config = Config::new(Model::QL820NWB, "serial".to_string(), 
                        Media::Continuous(ContinuousType::Continuous62Red))
    .two_colors(true); // Enable red and black printing

pub fn compress(self, flag: bool) -> Self

Enable or disable data compression.

Uses PackBits compression to reduce USB transfer size. Automatically disabled for QL-800 model due to hardware limitations.

Arguments

• flag - true to enable compression

Example

let config = Config::new(Model::QL820NWB, "serial".to_string(), 
                        Media::Continuous(ContinuousType::Continuous62))
    .compress(true); // Enable compression
