Fazer Impressão da div printMe e falhando miseravelmente (Vue.js)

ANRVA6 · Fevereiro 15, 2022

Então, amigos segue a live demo:

http://feeling.atwebpages.com

Uma pena que minha outra conta eu perdi com meu e-mail.

Seguinte, eu peguei daqui um exemplo do que eu precisava, que é um 'cardápio' que consiga adicionar o produto clicando na foto e no final, preciso q ele some e faça uma mini tabelinha com os itens.

Até ai, perfeito, tá tudo beleza e funcionando.

Porém, não tive jeito de conseguir fazer a impressão apenas da parte que preciso, que seria o que você comprou. Não preciso confirmação de nenhum tipo de sistemas reais bancários, apenas imprimir mesmo numa impressora térmica o cupom com os itens e quantidade.

Segue meu ''código'' que tá meio bagunçado mas legível:

Bom, eu tentei de tantas maneiras e diversos tutoriais, que ficou evidente que não vou conseguir sem ajuda.

Não me importa se ele irá criar uma nova página com os dados nem nada, desde q ele clique no botão e imprima na impressora padrão. Li em foruns gringos que tem navegadores que não lidam bem com tipos de codigo para impressão sem diálogo, se for o caso posso usar qualquer navegador na máquina, minha ideia é que online nunca vai precisar ''reinstalar'' sistemas nesse pc. Se só conseguir fazer com diálogo, tbm é possível, mesmo q prefira sem nenhum popup.

Fico na esperança da ajuda dos amigos, pois estava a bastante tempo sem programar nada e, agora graças a deus com mais projetos, irei tirar a ferrugem, mas de momento necessito desse apoio da comunidade.
