Printer which supports Job Storage 3 5 2 Secure Pull Printing HP ePrint Enterprise server supports the following HP Secure Pull Printing solutions in addition to non HP Secure Pull Printing solutions HP Access Control SPP HP Access Control SPPE Section 3 3 Communication security 11 4 Service Infrastructure This chapter describes the service level of HP ePrint Enterprise assisting IT professionals with dimension deployments It also describes how the system behaves in situations of peak and stress which helps understand the limitations of the system 4 1 Assumptions All performance and load analysis stated in this chapter are based on a set of assumptions which attempt to describe a real use scenario This means that any deviation from these assumptions will necessarily impact the actual results observed during normal use For this analysis the following assumptions were made 4 1 1 Average Print Job APJ An APJ refers to the average computational power necessary to transfer open render and print any one of the following files Microsoft Word document docx 14 pages 3 images 8 000 characters 505 KB e Microsoft Excel spreadsheet xlsx 3 tabs 116 KB e Adobe PDF file 8 pages 830 KB e JPGimage 2512x 2011 resolution 612 KB Although each file is different in size and complexity of processing in practical terms this service level analysis assumes that the files are sent to HP ePrint Enterprise
7. basis i e printers are assigned to host servers It is a good idea to balance this assignment based on traffic to those printers For example if 2096 of the printers are responsible for 8096 of the traffic you should consider distributing the printers instead of concentrating them on the same primary or secondary server If there are a total of 1000 printers 200 of them used 8096 of the time you could have approximately 5 HP ePrint Enterprise servers each one getting 40 of those 200 more popular devices The number of BES servers typically does not qualify as a good criterion for distributing HP ePrint Enterprise servers There is no technical requirement binding BES and HP ePrint Enterprise servers BES is just a secure channel enabler However the total number of users associated to those BES may indicate a distribution factor Section 5 1 Sizing of a primary secondary layout 17
