I have not seen any problems with my ink jet printer on returning from a 2-3 week holiday – admittedly only once or twice a year.
My advice would be to make sure cheap compatible cartridges are available for the printer.
If you don’t use colour, consider a laser printer – they can be had from around £50. Although the replacement toner cartridges might appear expensive (compared with compatible ink jet cartridges), they work out at not much more that 1p in toner per print.
