As shortly as possible about how argyrotype print is done, because long version would take few pages and that’s #TLDR.

Everything starts and ends with paper and it’s quality. You start with coating paper with silver-based emulsion. Layer should be thin but it depends on paper how fast it absorbs liquids. Sometimes the same paper brand from one manufacturer differs between batches due to differences in celulose used for production. Especially those hand-made papers. If there are any imperfections in paper structure, chemical residues, they might appear now because of difference in emulsion absorbtion. If that happens paper goes to trash or I develop as an expample for future reference. Emulsion dires between one and two hours in the envitonment with controlled humidity. After it dries it can be exposed. It’s a contact exposure so print is as big as a negative. Argyrotype, the same as cyanotype is uv sensitive so exposure is done under uv lamp (UVA part of spectrum) and it takes between 4 to 16 minutes depending on paper and negative density. Once exposed development starts. There are three parts: 7-10 minutes wash in distilled water to get rid of emulsion excess, 2 – 3 minutes bath in actual developer (sodium thiosulfate) and 15-20 min bath in running water. After develompment paper needs to dry completely and it takes about 24 to 36 hours in the press. Emulsion changes color in each stage from yellow before exposure through orange and brown during development and drying to black and white or various tones of sepia once dry. Again, final result depends on paper and you can examine it once completely dry so if there are any flaws … I start over. My record so far is 19 prints of one work which due to the specific paper is not done but I have not failed, I’ve found 19 ways that it won’t work 😉
