Abstract:
1. A method for printer stability enhancement in a multiple printer printing system, said method comprising: receiving into a multiple printer printing system a print job comprising first and second printing roles; assigning said first printing role to a first printer of said printing system; assigning said second printing role to a second printer of said printing system; using said first printer to perform said first printing role and using said second printer to perform said second printing role; determining a first printer stress state of the first printer of the printing system, wherein said step of determining the first printer stress state comprises receiving first printer stress data from said first printer, said first printer stress data comprising data that relate to a plurality of first printer stress parameters including at least two of: first printer toner age; first printer toner concentration; first printer area coverage; first printer streaks; first printer development field; first printer laser power; first printer charge level; determining a second printer stress state of the second printer of the printing system, wherein said step of determining the second printer stress state comprises receiving second printer stress data from said second printer, said second printer stress data comprising data that relate to a plurality of second printer stress parameters including at least two of: second printer toner age; second printer toner concentration; second printer area coverage; second printer streaks; second printer development field; second printer laser power; second printer charge level; comparing said first printer stress state to said second printer stress state, wherein said step of comparing said first printer stress state to said second printer stress state comprises: reassigning said first printing role of the print job to said second printer and reassigning said second printing role of the print job to said first printer if said first printer stress state is different than said second printer stress state; wherein said step of reassigning said first printing role of the print job to said second printer and reassigning said second printing role of the print job to said first printer comprises: sending print data defining said first printing role of said print job to said second printer and using said second printer to print said data defining said first printing role; sending print data defining said second printing role of said print job to said first printer and using said first printer to print said data defining said second printing role.
