This paper aims to offer an insight towards a new model system which supports roaming print based on the analysis of current printing system structure. Practically, it helps users accomplish the printing tasks without temporal and spatial constraints. Therefore, it decreases the possibilities of random printing and lays the foundation for future research on print content filtering, task log auditing and other related issues. Moreover, the paper focuses on the arithmetic description on three models of I-dentity authentication, job scheduling and content inspection.%在对业内现有打印体系结构分析的基础上,本文提出支持打印任务漫游的新体系模型研究思路,用户提交的打印任务可以根据需要来完成,较好地解决了打印任务受到时间和空间限制的问题,同时还降低了打印的成本和盲目性,以及为实现打印内容过滤、任务日志事后审计等工作奠定了研究基础.本文还对身份认证、作业调度及内容检查等三个模块进行了算法的描述.
