The currently published printed copies of Yan Zhenqing's "Zi Shu Gao Shen" are generally ink copies, and with current printing technology, it is impossible to print very poorly. There are many versions and can be found online. As long as it is not marked as an enlarged version, it meets your requirements. The amplification is for advertising effect, because some people like to enlarge the book. In fact, the original characters are large enough and there is no need to enlarge them at all.
The better versions mainly include:
1. The Shanghai Painting and Calligraphy Publishing House edition, single volume, several editions before and after, all are okay. There is also a version included in the official calligraphy series of past dynasties. Originally they should all be one. Some single-series notebooks have shortcomings: reflective and dazzling.
2. The Shanghai Ancient Books Bookstore once published a single volume, which looked good. There is an online auction, but of course it is a bit expensive.
A more reliable method: search online, preferably the one with pictures on the inside pages. Search and compare yourself.
This is a common post and relatively easy to get. good luck!
