One layout file, three outputs: building printer test pages as real CMYK PDFs with Astro

·1 views

I built testpageforprinter.com, a free set of printer test sheets (color, black and white, CMYK, alignment, nozzle check, scale, photo, duplex). Most "printer test page" sites hand you one generic image. I wanted sheets that really are what they claim to be: vector, in the right color space, at the right size. This post covers the part I found most interesting to build. A test page that goes through a browser print dialog can quietly be wrong in three ways: the page is scaled ("Fit to page"), so an alignment test lies to you; colors are converted to RGB, so a "CMYK" test is not testing the cya

Wiretables: tables for Laravel and Livewire written in Blade

Table packages for Livewire usually define the columns in PHP arrays, which is comfortable until one cell needs something the configuration did not plan for.
