PrinterMap User Guide

Each managed printer requires a static amount of reporting and status information. 
Allow for an additional 412Kb per managed printer to support reporting data. 
This covers a rolling two-year span of data.  Please note that this space is 
allocated for each printer when it is discovered. 
Given these requirements, managing 100 printers would require an additional 
41.2Mb of disk space over and above the 9Mb required for PrinterMap programs 
and log files.   Below is a table showing the additional disk space required for 
managing 10, 100 and 1000 printers if the reporting option is enabled.

Projecting Discover Time 
The following is an example of Discover process time. 
The System Administrator chooses to discover network printers through a local 
range of IP addresses. This range contains 35 entries, of which 6 are printers. 
Discover takes approximately 3.0 seconds per entry or 105.0 seconds total. 
Projecting Network Traffic 
In this scenario, the Discover time is affected by total number of entries in the 
range of IP addresses and the number of devices being determined as printers. A 
greater number of IP address entries increase the discover time even for the same 
amount of printers. 
The following is a collection of data illustrating the amount of network activity 
you can expect when using PrinterMap. To demonstrate expectations of traffic, an 
example has been used of a standard network of 100 printers. 
Average SNMP request packet size: 200 bytes 
Average SNMP response packet size: 200 bytes
