Regarding head of account

Printer Catridges do not meet the asset recognition criteria. Hence, they are to be considered under Printing & Stationery and charged to P&L A/c

I agree with Manish Jain.

such expenses can be treated as Fixed Asset only if it increases the value of the asset or extends the life of asset or increases the performance of the asset.

Printer Cartriges are replaced like day to day maintenance they are consimables and hence of revenue nature

Agree with Manish Dave

Consumables or computer maintenance 

As it is an recurring expense charged to profit and loss a/c

Thanks.I too thought same way but want to clarify once again.Thanks once again

All  suggestions are correct.

I want to know purchase of  printer comes under which head of account whether office expenses or part of Fixed Assets:Computers.
