• Because of an unkown error the printer can not be used as a regular printer. Before each print, you have to uninstall an reinstall it. That is what the file printer.sh is doing.
• Default page size is 48mm by 105mm. To change you need to edit the file ZJ-58.ppd. Copy the line *PageSize X48MMY105MM/58mm x 105mm:... and change the length of the paper and the resolution. Afterwards change the default size *DefaultPageSize: to your new size.
• You can generate your print files with basiljs, html2pdf or simply use a textfile.
• You can start the print command from any source like Bash, Processing (Java), Python, a local Webserver (PHP, NodeJS), basiljs, MaxMSP and many more.
